Nano silicon boosts tumour fight
The tiny science of nanotechnology could give a big boost to cancer patients undergoing tumour treatments. BrachySil, by biotech firm pSivida, is a silicon-based nanoscale system that takes drugs direct to the tumour site. Silicon's structure carries an electrical current, is porous and adaptable. This means the right amount of drug can be released when needed.
