A sandwich assay labelled with gold nanoparticles can be mechanically and optically detected with the help of a silicon cantilever, allowing cancer biomarkers to be identified in serum at very low concentrations.
Freeze-casting cellulose nanofibres, graphene oxide and clay results in insulating and fire-resistant foams that could improve the energy efficiency of buildings.
Careful, low-noise measurement techniques allow record quality factors to be determined in ultraclean, suspended carbon nanotube resonators, which are comparable to those of much larger resonators.
G-quadruplex DNA molecules adsorbed on a mica substrate can transport currents of more than 100 pA over distances of more than 100 nm by means of a hopping mechanism.
