Currently, tests to detect the presence of infection or disease require a sample of blood from a patient, which is later analyzed in a laboratory to detect markers of disease
The measurement tool, known as the Materials Analysis Particle Probe (MAPP), was built by a consortium that includes Princeton University and the University of Illinois at Urbana-Champaign
While police are trying out potential tools, no device currently on the market has been shown to quickly provide a precise measurement of a driver's marijuana intoxication as effectively as a breathalyzer gauges alcohol intoxication
The chemists attach luminescent compounds to tiny gold structures to form biologically safe ‘nanoagents’ that are attracted to calcium-rich surfaces, which appear when bones crack—even at a micro level
To understand how molecules undergo light-driven chemical transformations, scientists need to be able to follow the atoms and electrons within the energized molecule as it rides on the energy "roller coaster"
