Upconverting nanolasers from subwavelength plasmons

To design these nanolasers, researchers combined arrays of nanopillars with nanoparticles that can absorb two photons of light and emit them as a single photon with higher energy.

A genetic nano-toolkit for the generation of new bacterial magnetic nanoparticles

Scientists have developed a modular system for the genetic reprogramming of bacteria, thereby turning the organisms into cell factories for multifunctional magnetic nanoparticles that combine various useful functions and properties. Because of their exceptional magnetic properties and good biocompatibility, these nanoparticles might be a promising new material in the biomedical and biotechnological field.

Crumpled graphene makes ultra-sensitive cancer DNA detector

Crumpling graphene makes it more than ten thousand times more sensitive to DNA by creating electrical 'hot spots'.
