Bovine blood keeps gold nanoparticles stable

(Phys.org) —A protein from cow blood has the remarkable ability to keep gold nanoparticles from clumping in a solution. The discovery could lead to improved biomedical applications and contribute to projects that use nanoparticles ...

Improving DNA amplification from problematic plants

The polymerase chain reaction (PCR) is a common technique used to amplify, or copy, pieces of DNA. Amplified DNA is then used in genetic analyses for everything from medicine to forensics. In plant research, PCR is a vital ...

Glowing flowers for ultra-trace analysis of TNT

(Phys.org)—Highly sensitive and highly selective tests are important for the early detection of disease, the detection of environmental toxins, or for the detection of explosives at airports. Increased selectivity for the ...

First nanoscale mass spectrometer created

Using devices millionths of a meter in size, physicists at the California Institute of Technology (Caltech) have developed a technique to determine the mass of a single molecule, in real time.
