Gold nanoparticles are made up of metallic gold atoms to create a crystal structure of 1-100 nm.

MIT researchers develop new nanodevice that can help overcome drug resistance

Chemotherapy often shrinks tumors at first, but as cancer cells become resistant to drug treatment, tumors can grow back. A new nanodevice developed by MIT researchers can help overcome that by first blocking the gene that confers drug resistance, then launching a new chemotherapy attack against the disarmed tumors.

Korean scientists produce flexible, stable monolayers of protein-bound gold nanoparticles

Free-standing nanoparticle films are of great interest for technical applications, such as the development of nanoelectronic devices. In the journal Angewandte Chemie, Korean scientists have introduced very flexible and stable monolayers of gold nanoparticles made by a self-assembly process based on protein aggregation. The films were used to coat wafers up to 10 cm in diameter.

MU researcher developing nano-scale molecules to image, treat different diseases

Nanomedicine is the medical application of nanotechnology, or the use of microscopic structures to diagnose, image, treat and prevent disease. Current problems in nanomedicine include understanding and anticipating the potentially toxic impact these nanostructures have on the body and the environment once they're released.
