Nanoparticle cocktail targets and kills tumors

By / January 19, 2010

A team of researchers from the National Cancer Institute’s Center of Cancer Nanotechnology Excellence have teamed up to develop a “cocktail” of different nanometer-sized particles that work in concert within the bloodstream to locate, adhere to and kill cancerous tumors. The work that was published in the Proceedings of the National Academy of Sciences. “This…

Photovoltaic implant gives sight to the blind

By / December 30, 2009

Researchers at Stanford University recently announced that they have developed a new artificial retina implant that uses photovoltaic power and could help the blind see. The problem with previous implants was that there was no way send power to the chip in order to process light and data inside the eye. Now, miniature photovoltaic cells…

New beryllium reference material for occupational safety monitoring

By / September 23, 2009

Researchers at NIST have produced a new reference material for beryllium. The rare-earth metal used as a hardener in high-performance alloys and ceramics can cause berylliosis — a chronic, incurable and sometimes fatal illness. The new reference material is expected to dramatically improve methods used to monitor workers’ exposure and aid in contamination control as…

Nanodiamonds move into gene therapy

By / September 2, 2009

A team of Northwestern University researchers has figured out a way to use nanodiamonds to deliver DNA for gene-therapy application. By modifying the surface of nanodiamond particles with a special polymer, a group led by Dean Ho found they could reach a delivery efficiency that is 70 times greater than that of a conventional standard…
