Much research is being conducted into the design of intelligent drug delivery systems that will carry and deposit therapeutics to where they are needed in the body, without affecting or harming any other cells in the body.
Such specific delivery of medicine will revolutionise healthcare, not least because of the elimination of damaging side effects, but also due to the ability to directly control the ambush of harmful, unwanted tissues such as cancerous growths and tumours.

Ancient medicine is finding its place in modern science as researchers in India and America explore the development of a novel cancer therapy that combines the curry spice turmeric with advances in nanomedicine.

A multidisciplinary team of UCLA scientists have successfully differentiated metastatic cancer cells from normal cells in patient samples using leading-edge nanotechnology that measures the softness of the cells. The method could provide a new diagnostic tool for cancer.

The first cochlear implants to restore hearing to the deaf were developed by Graeme Clark at the University of Melbourne in Australia more than 30 years ago and are today in widespread use around the globe.
In comparison, the restoration of sight has proved far more difficult, with visual prostheses capable of achieving the same level of accuracy still a long way from reaching international use.
