Early Nanotech Versus Cancer

Fight Aging!

Do you want to live a longer life in good health? Simple practices can make some difference, such as exercise or calorie restriction. But over the long haul all that really matters is progress in medicine: building new classes of therapy to repair and reverse the known root causes of aging. The sooner these treatments arrive, the more lives will be saved. Find out how to help »

Canada.com reports on the more promising and widespread approaches to the use of nanoscale engineering in cancer therapies: "The [study] involved engineering nanoparticles embedded with the cancer drug Taxotere. The particles were then injected directly into human tumours created from prostate cancer cell lines and implanted into the flanks of mice. ... The technology being tested involves a nanoparticle made of a hydrogen and carbon polymer with bits of drug bound up in its fabric and attached to a chemical that hones in on cancer cells. The polymer gradually dissolves, exposing the nuggets of drug little by little." Killing cells is easy, but killing specific cells is very hard. Accurate, targeted delivery is the hard problem of the day.
