Safer Joint Replacements
Abstract:
Researchers led by Paula Hammond, professor of chemical engineering at MIT, are using a polymer-coating technique called layer-by-layer assembly to load large concentrations of drugs into implant coatings without making them too thick. Hammond's group builds up these films by dipping an implant alternately in solutions of negatively and positively charged molecules such as polymers and drugs. The difference in surface charge holds each layer tightly to those above and below it. This process leads to very thin layers of materials, on the order of tens of nanometers thick. The drugs will be released when the polymers biodegrade inside the body.
