A megalibrary of nanoparticles

Using straightforward chemistry and a mix-and-match, modular strategy, researchers have developed a simple approach that could produce over 65,000 different types of complex nanoparticles, each containing up to six different materials and eight segments, with interfaces that could be exploited in electrical or optical applications.

Tuning of Optical absorbance of graphene quantum dots by high magnetic fields

Scientists report the synthesis of graphene quantum dots under an external high magnetic field and their applications in photothermal therapy.

A new way to count and identify microscopic particles in fluids

A new method is proposed to automate the measurement of nano- to microscale particles suspended in fluid. The single particle extinction and scattering (SPES) method can accurately determine the material properties and size distribution of individual particles.
