Selective gas sensing with pristine graphene

It has been known for some time that graphene can be used for detection of individual gas molecules adsorbed on its surface – a graphene sensor can detect just a single molecule of a toxic gas. However, the extremely high sensitivity of graphene does not necessarily translate into its selectivity to various molecules. In other words, it can be detected that some molecules attached to the graphene surface change the resistivity of a graphene field-effect transistor but one cannot say what kind of a molecules have attached. Scientists have therefore thought that truly selective gas sensing with graphene devices requires the functionalization of graphene surface with some agents specific for different gas molecules. In new research, though, scientists have now found that chemical vapors change the noise spectra of graphene transistors. The noise signal for each gas is reproducible, opening the way for practical reliable and simple gas sensors made from graphene.

Boron-nitride nanotubes show potential in cancer treatment

A new study has shown that adding boron-nitride nanotubes to the surface of cancer cells can double the effectiveness of Irreversible Electroporation, a minimally invasive treatment for soft tissue tumors in the liver, lung, prostate, head and neck, kidney and pancreas.

Cells in blood vessel found to cling more tightly in regions of rapid flow

Researchers at the University of Washington have studied vessel walls and found the cells pull more tightly together, reducing vascular leakage, in areas of fast-flowing blood. The finding could influence how doctors design drugs to treat high cholesterol, or how cardiac surgeons plan their procedures.

New guide for research on multiblock polymers emerges

Thanks to advances in polymer chemistry and a wide variety of monomer constituents to choose from, the world of multiblock polymers is wide open. These polymers can result in an astonishing array of materials, customizable to almost any specification. However, the flood of options could be overwhelming, without a theoretical framework to guide research.

Slicing mitotic spindle with lasers, nanosurgeons unravel old pole-to-pole theory

The mitotic spindle, an apparatus that segregates chromosomes during cell division, may be more complex than the standard textbook picture suggests, according to researchers at the Harvard School of Engineering and Applied Sciences (SEAS).
