Engineers have invented a way to spray extremely thin wires made of a plant-based material that could be used in N95 mask filters, devices that harvest energy for electricity, and potentially the creation of human organs. The method involves spraying methylcellulose, a renewable plastic material derived from plant cellulose, on 3D-printed and other objects ranging from electronics to plants, according to a Rutgers-led study in the journal Materials Horizons.
Laser-induced melting occurs nonuniformly in polycrystalline gold thin films—a finding that may be important for precision part micromachining.
A Rutgers-led team has developed a tool to monitor influenza A virus mutations in real time, which could help virologists learn how to stop viruses from replicating. The gold nanoparticle-based probe measures viral RNA in live influenza A cells, according to a study in The Journal of Physical Chemistry C. It is the first time in virology that experts have used imaging tools with gold nanoparticles to monitor mutations in influenza, with unparalleled sensitivity.
A Rutgers-led team has created better biosensor technology that may help lead to safe stem cell therapies for treating Alzheimer’s and Parkinson’s diseases and other neurological disorders. The technology, which features a unique graphene and gold-based platform and high-tech imaging, monitors the fate of stem cells by detecting genetic material (RNA) involved in turning such cells into brain cells (neurons), according to a study in the journal Nano Letters.
