Ultrasensitive DNA quantification by light scattering

Traces of biomolecules such as DNA can be detected with a new "dynamic" technique based on the observation of association and dissociation events of gold nanoparticles. If the desired DNA sequence is present, it can reversibly ...

Chemists perform 'surgery' on nanoparticles

A team of chemists led by Carnegie Mellon University's Rongchao Jin has for the first time conducted site-specific surgery on a nanoparticle. The procedure, which allows for the precise tailoring of nanoparticles, stands ...

How gold can recycle biofuel waste into useful additive

Gold nanoparticles serve as catalysts for obtaining valuable chemical products based on glycerol. Scientists from Tomsk Polytechnic University and their international colleagues are developing gold catalysts to recycle one ...

Gold nanoparticle chains show promise as light conductors

Today's computers are faster and smaller than ever before. The latest generation of transistors will have structural features with dimensions of only 10 nanometers. If computers are to become even faster and at the same time ...

Nano fiber feels forces and hears sounds made by cells

Engineers at the University of California San Diego have developed a miniature device that's sensitive enough to feel the forces generated by swimming bacteria and hear the beating of heart muscle cells.
