When A Good Nanoparticle Goes Bad

Short description


Understanding how nanoparticles change form may help solve energy needs

Article body


Researchers at Cornell University recently made a major breakthrough when they invented a method to test and demonstrate a long-held hypothesis that some very, very small metal particles work much better than others in various chemical processes such as converting chemical energy to electricity in fuel cells or reducing automobile pollution.
The breakthrough, reported in this week's edition of the journal Nature Materials, also came with a surprise. By devising a way to watch individual molecules react with a single nanoscale particle of gold in real time, researchers confirmed that some gold particles are better at increasing the rate of a chemical reaction than others, but they also found that a good catalyst sometimes spontaneously turns bad.
Understanding why these particles change and how to stabilize the "good" particles may lead to solutions for a wide range of problems such as the current global energy challenge.

The Akiyama-probe has been developed in cooperation with the Institute of Microtechnology (IMT) at the University of Neuchâtel for the NANOSENSORS™ brand that is specialized on cutting edge scanning probes for Atomic Force Microscopy (AFM) applications. The product is called the Akiyama-probe or A-probe to honour its inventor Dr. Terunobu Akiyama. It is a novel self-sensing and – actuating probe based on a quartz tuning fork combined with a micromachined cantilever for dynamic mode AFM.
It features a symmetrical arrangement of a U-shaped silicon cantilever attached to the two prongs of a quartz tuning fork. The tuning fork serves as an oscillatory force sensor that governs the tip vibration frequency as well as the amplitude and ensures a high mechanical Q-factor. The force constant of the probe is determined by the cantilever and can be adjusted independently from the resonance frequency.
The Akiyama-probe requires neither optical detection, nor an external shaker. A-Probe occupies only a small volume above the sample. These features make it very attractive for creating a new generation of scanning probe microscopy (SPM) instruments.
Up to now the probe was only available to and via AFM manufacturers who sell instruments with A-probe capability. Starting November 2008 the Akiyama-probe will also be available to end-customers via our regular distribution channels. For this occasion NANOSENSORS™ has dedicated a complete website akiyamaprobe.com which offers ample information on this very special product.

A revolutionary new gold nanoparticle manufacturing method has been developed that results in gold nanowires that are upwards of 2 microns in length and only 20 nm in diameter. These ultra-long devices exhibit tremendous photothermal properties, converting up to 90% of incident light energy to heat. Their tunable optical absorption range is from 1 to 10 microns.
Nanowires are an extension of the technology currently employed by Nanopartz™ for nanorods. Gold nanorods have recently found huge successes in cancer therapy. Gold nanorods are also used for blood testing in diagnostics; as optical contrast agents in imaging; in material science, optics, negative refractive index materials such as the “Harry Potter Cloak;” and for improving the density of optical data storage in compact disks.
With tunable absorptions in the near to mid-IR, solar cell manufacturers can use these devices to improve the efficiencies of their devices since current devices do not absorb well at these wavelengths. Their shapes lend themselves to be a component in better optical devices like polarizers, filters, and negative refractive index materials. Many scientists have employed these devices as wires in nanocircuitry. Nanopartz™ is also experts in conjugating surface coatings to these gold nanoparticles. These conjugation provide the mechanical linkage necessary for many of these applications.
These devices are now available for evaluation at pre-production quantities. "We are very excited at the potential applications of these gold nanoparticles,” said Christian Schoen, President of Nanopartz™.

According to a paper by Hatice Şengül and colleagues at the University of Illinois at Chicago, strict material purity requirements, lower tolerances for defects and lower yields of manufacturing processes may lead to greater environmental burdens than those associated with conventional manufacturing. In a study of carbon nanofiber (CNF) production, Vikas Khanna and colleagues at The Ohio State University found, for example, that the life cycle environmental impacts may be as much as 100 times greater per unit of weight than those of traditional materials, potentially offsetting some of the environmental benefits of small size of nanomaterials.
Materials engineered at dimensions of 1 to 100 nanometers­ (1 to100 billionths of a meter) ­exhibit novel physical, chemical and biological characteristics, opening possibilities for stunning innovations in medicine, manufacturing and a host of other sectors of the economy. Because small quantities of nanomaterials can accomplish the tasks of much larger amounts of conventional materials, the expectation has been that nanomaterials will lower energy and resource use and the pollution that accompanies them. The possibility of constructing miniature devices atom-by-atom has also given rise to expectations that precision in nanomanufacturing will lead to less waste and cleaner processes.
“Research in this issue reveals the potential of environmental impacts from nanomanufacturing to offset the benefits of using lighter nanomaterials,” saysGus Speth, dean of the Yale University School of Forestry & Environmental Studies. “To date, most attention has focused on the possible toxic effects of exposure to nanoparticles­ and appropriately so. But the ‘old-fashioned’ considerations of pollution and energy use arising from the production technologies used to make nanomaterials need attention as well.”
Other topics explored in the special issue include: · Approaches for identifying and reducing the life cycle hazards of nanomaterials · Quantified life cycle energy requirements and environmental impacts from nanomaterials · Tradeoffs between nanomanufacturing costs and occupational exposure to nanoparticles · Efficiency of techniques for nanomaterials synthesis · Improvement of the sustainability of bio-based products through nanotechnology · Industrial frameworks for responsible nanotechnology · Industrial and public perception about the risks and benefits of nanomaterials · Governance and regulation of nanotechnology
Industrial ecology is a field that examines the opportunities for sustainable production and consumption, emphasizing the importance of a systems view of environmental threats and remedies. “Through the use of tools such as life cycle assessment, green chemistry and pollution prevention, industrial ecology takes a broad and deliberate view of environmental challenges,” states Reid Lifset, editor-in-chief of the Journal of Industrial Ecology. “This special issue shows the power of this approach.”
Roland Clift, Professor of Environmental Technology in the Centre for Environmental Strategy at the University of Surrey and Shannon Lloyd, Principal Research Engineer in the Sustainability & Process Engineering Directorate at Concurrent Technologies Corporation, served as guest editors. Support for this special issue was provided by the Educational Foundation of America, in Westport, Conn. and the Project on Emerging Nanotechnologies of the Woodrow Wilson International Center for Scholars in Washington, D.C.

Scholars and scientists alike all seem to be in agreement that nanotechnology will undoubtedly be a significant science in future years and this is evidenced by the noteworthy focus on and release of fresh nanotechnology news. Some are going as far as calling nanotech research the 21st century science. Current nanotech research which focuses directly on micro particles and nanostructures will be used in the future in cosmetics, beauty aids, wine flavorings, cleaning products, and in the production of self cleaning clothing.
The future of nanotechnology, as documented in recent nanotechnology news, also promises some considerable advances in the medical fields and in the food industries. This certainly is promising for anyone interested in the study of nanotechnology information and/or nanotechnology jobs. Yet, with all of the positive views pertaining to nanotechnology and the ever present advances in nanotechnology, some scientists and scholars actually fear the act of trusting the science, and are worried about the potential ramifications that may or may not accompany nanotechnologies.
Considerable concern exists with the question pertaining to what effect nanoparticles have on the human body, if any effect at all. This question, to this date, remains unanswered, and some scientists fear that the presence of nanoparticles in the human body, over time, may pose some sort of threat. Since nanoparticles are so tiny, there is considerable belief that nanoparticles can sneak through natural defenses, into cell membranes, and potentially transport foreign materials between human strands of DNA. The effects of nanoparticles on the human body have potentially harmful results and this prospect is considerably frightening to some. Some studies recently released aren’t too promising. Fish that have consumed carbon nanoparticles have been tested and have developed brain cancer, so there may indeed be a correlation between the two. Also, alternative studies conducted on rats reveal a correlation between inhaled carbon nanotubes and respiratory dysfunction: ailments considerably similar to the symptoms one develops from asbestos exposure.
John Balbus, Chief Health Scientist at Environmental Defense, asserts that there is little to fear, but that prudence is needed. There are currently some institutions which are demanding and campaigning for rigid checking systems and testing. Currently, the Food and Drug Administration announced that nanoparticles pose no public hazard and that anything manufactured with nanotechnology does not require unique and specified testing. This can prove detrimental to the public if, in the future, scientists suddenly begin revealing an issue with nanoparticles and how they affect human beings on a cellular level through exposure. The United Kingdom government recently released a report suggesting that stringent detection and nanoparticle measurement restrictions need to be implemented. The level of human exposure to nanoparticles also needs to be monitored, the degree of potential toxicity must be revealed, and the environmental effects of nanotechnology must also be assessed.

So when scientists uncovered an additional potential cause for this incurable form of lung cancer, the unthinkable became a reality.
According to researchers based out of the Woodrow Wilson International Centre for Scholars in Washington D.C., the early 90's development of carbon nanotubes has been an amazing feat for technological applications, however, it has not gone without its price. Specifically, carbon nanotubes may be causing harm to the human body in the form of mesothelioma cancer.
If the carbon nanotubes are introduced into the wrong environment, the development of lesions and inflammation of the lungs occurs - symptoms similar to that of mesothelioma cancer and asbestos exposure. Animals that were exposed to carbon nanotubes was how the researchers discovered the link. Dr. Andrew Maynard, who published a study in the journal Nature Nanotechnology, described the use of nanotubes and the potential link to mesothelioma cancer. The ability for nanotubes to conduct heat and electricity is what is driving their use, he said.
Mostly, Dr. Maynard explains, the nanotubes are being implemented into sports equipment. There are no regulations in place with nanotechnology or the use of nanotubes.
What Are Nanotubes?
Nanotubes have been deemed the poster child of nanotechnology, Maynard said. The nanotubes are cylindrical structures comprised of carbon atoms that have been rolled together. Maynard's study found that when mice were exposed to nanotubes, they developed asbestos-induced symptoms within the lungs. Nanotubes are considered safe until broken.
The use of nanotubes includes:
* a variety of sports equipment
* bicycle frames
* tennis rackets
* electronic gas detectors
* radios
Additionally, because of the strength of nanotubes, many consider its future use to vastly effect several business ventures and areas, and be widely used in industries including:
* aerospace
* automobile
* airplanes
* television box productions
* medical
* environmental uses
Working with Nanotubes
While the National Institute for Occupational Safety and Health (NIOSH) is doing research on nanotoxicology, there is little knowledge or research currently available regarding the safety of using nanotechnology.
Additionally, Dr. Maynard noted that because of the ever-increasing nanotechnology industry, which is likely to be worth $2.6 trillion by 2014, it will be difficult to adequately and accurately assess nanotechnology safety because of the technology's quick growth, which is also being used in the food industry.
Transparency of nanotoxicology among some nanotechnologically-produced products may fall into the hands of manufacturers and producers, which John M. Balbus, heatlh program chief for the Environmental Defense Fund told the Washington Post that with open communications nanotechnology will flourish, but without it, another wave of unknowing mesothelioma victims will occur.
However, he noted that upfront communication regarding the dangers of nanotechnology with the public may increase because of the previous mistakes made by other industries in hiding mesothelioma conditions from the public.
Finding Help with Nanotube Related Mesothelioma
Individuals, especially nanotube factory workers who have previously worked with carbon nanotubes or have been exposed to the potential dangers associated with the nanotubes and developing mesothelioma should receive medical attention immediately. It may also become necessary for these individuals to locate a law firm with knowledge of mesothelioma-related litigation in order to develop a mesothelioma lawsuit.
Because of the nature of the industry and the continued funding flooding into carbon nanotube research it is important to develop a lawsuit that will also alert others, in a similar predicament, and provide aware of the potentially serious health risks associated with nanotechnology.
Further, because only 5 percent of the funding, which consists of billions of dollars annually, provided by the National Nanotechnology Institute is going toward health and safety research, it is important for individuals with nanotube-induced mesothelioma to develop a lawsuit that may offer monetary compensation to victims suffering from this irreversible and deadly lung cancer.
