New technique allows low-cost creation of 3-D nanostructures

Researchers from North Carolina State University have developed a new lithography technique that uses nanoscale spheres to create three-dimensional (3-D) structures with biomedical, electronic and photonic applications. The ...

A levitated nanosphere as an ultra-sensitive sensor

Sensitive sensors must be isolated from their environment as much as possible to avoid disturbances. Scientists at ETH Zurich have now demonstrated how to remove from and add elementary charges to a nanosphere that can be ...

Researchers manipulate gold-coated nanoparticles with lasers

Tiny glass nanospheres coated on one side with a very fine gold film: LMU scientists have shown that particles modified in this way can be moved about with high precision using laser beams, creating an optically controlled ...

Multitasking plasmonic nanobubbles kill some cells, modify others

(Phys.org)—Researchers at Rice University have found a way to kill some diseased cells and treat others in the same sample at the same time. The process activated by a pulse of laser light leaves neighboring healthy cells ...

Calcium carbonate templates for drug delivery

(Phys.org) -- The fast and targeted delivery of drugs to the focus of a disease could soon be made easier. Helmuth Möhwald and his colleagues from the Max Planck Institute of Colloids and Interfaces in Golm, Potsdam, ...
