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 ...

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 ...

Research tests which nano system works best cancer treatment

(Phys.org) —In current research related to improving cancer treatments, one promising area of research is the effort to find ways to selectively pinpoint and target cancer cells while minimizing effects on healthy cells.

Nanoparticles: A simpler route to hollow carbon spheres

Hollow carbon nanoparticles are strong, conduct electricity well and have a remarkably large surface area. They show promise in applications such as water filtration, hydrogen storage and battery electrodes—but commercial ...
