DNA nanotechnology researchers develop 'nanotrain' for targeted cancer drug transport

University of Florida researchers have developed a 'DNA nanotrain' that fast-tracks its payload of cancer-fighting drugs and bioimaging agents to tumor cells deep within the body. The nanotrain's ability to cost-effectively deliver high doses of drugs to precisely targeted cancers and other medical maladies without leaving behind toxic nano-clutter has been the elusive Holy Grail for scientists studying the teeny-tiny world of DNA nanotechnology.

Mysterious catalyst explained: how gold nanoparticles aid the production of plastic components

From methanol to formaldehyde - this reaction is the starting point for the synthesis of many everyday plastics. Using catalysts made of gold particles, formaldehyde could be produced without the environmentally hazardous waste generated in conventional methods. Just how the mysterious gold catalyst works has been found out by theoretical and experimental researchers at the Ruhr-Universität Bochum in a cooperation project.
