MIT: Gel Offers Controlled Drug Delivery

MIT researchers have demonstrated that a gel composed of small, woven protein fragments can successfully carry and release proteins of different sizes, potentially enabling delivery of drugs such as insulin and trastuzumab (Herceptin).

Furthermore, the researchers can control the rate of release by changing the density of the gel, allowing for continuous drug delivery over a specific period of time. The team, led by Shuguang Zhang, associate director of MIT's Center for Biomedical Engineering, reports its findings in the March 9 online edition of the Proceedings of the National Academy of Sciences.
