Tiny remote-controlled tubes may one day let doctors deliver potent drugs to the exact spots in the body they are most needed.
The nanotubes, which are typically about 100 nanometers long, or one ten-millionth of an inch, are made from a special polymer that conducts electricity.
Here's how it's done:
Drug molecules and fibers of a polymer that breaks down in the body are mixed together. The mixture is placed on the tip of a tiny gold electrode, a type of medical probe that can transmit or receive electrical signals.
Elevated intraocular pressure (IOP) is one of the most important risk factors for the development of glaucoma, which is a progressive optic neuropathy. Lowering IOP is currently the only therapeutic approach
The advent of more efficient methods to synthesize and screen new chemical compounds is increasing the number of chemical leads identified in the drug discovery phase. Compounds with good biological
