Researchers have made a discovery about the behavior of tiny structures called nanocantilevers that could be crucial in designing a new class of ultra-small sensors for detecting viruses, bacteria and other pathogens.
Small pieces of nucleic acid, known as siRNAs (short interfering RNAs), can turn off the production of specific proteins, a property that makes them one of the more promising new classes of anticancer drugs in development.
Opening a whole new interface between nanotechnology and neuroscience, scientists have used slender silicon nanowires to detect, stimulate, and inhibit nerve signals along the axons and dendrites of live mammalian neurons.
Researchers have created assemblies of nanowires that show potential in applications such as armor, flame-retardant fabric, bacteria filters, oil cracking, controlled drug release, decomposition of pollutants and chemical warfare agents.
An in-depth study of nanoparticle distribution in tumor-bearing mice has shown that targeted magnetic nanoparticles accumulate and cluster in both primary breast tumors and metastatic lesions that have developed in the lung.
