The article focuses on the role on nanotechnology in medical science. It is noted that the world in the midst of another explosion in medical technology with new challenges, ranging from antibiotic-resistant bacteria to scarce donor organs. It is mentioned that researchers have made enormous progress over the past decade to build tissues and organs. It is stated that natural designs could be altered with the sue of nanotechnology as it act like a reinforcement for synthetic tissues to provide them the strength, stiffness, and viscoelastic performance of natural membranes.

The article relates the struggles and efforts of U.S. chemical engineer Robert S. Langer to explore the potential of chemistry and chemical engineering in changing the world and improving human health care. Information on his polymer drug delivery project is provided. Langer says his efforts to obtain a patent for his polymer systems were turned down five times during the 1971-81 period. He co-founded a company called Enzytech to develop polymeric drug delivery systems.
