Sensor with exceptional performance for detecting nanoparticles

Nanodetector

Researchers have developed a sensor with exceptional performance for detecting nanoparticles. It’s long been thought that two’s company and three’s a crowd. But electrical and systems engineers at Washington University in St. Louis and their collaborators have shown that the addition of a third nanoscatterer, complementing two “tuning” nanoscatterers, to …

Burning of coal produces incredibly harmful nanoparticles

coal fired power plant

Environmental scientists led by the Virginia Tech College of Science have discovered that the burning of coal produces incredibly harmful nanoparticles of a highly unusual form of titanium oxide. When inhaled, these nanoparticles can enter the lungs and potentially the bloodstream. The particulates — known as titanium suboxide nanoparticles — …

Oldest nanomachines in biology is the bacterial flagellum

One of the oldest nanomachines in biology is the bacterial flagellum. This apparatus is evolutionary essential, endowing onto bacteria the ability to move. The flagellum shares high similarity with another bacterial structure, the injectisome, which as the name implies is how some bacteria deliver their content to infect a host. …
