Silk Microneedles

Dec-23-11 Engineers have used silk to develop a new form of microneedle, which can deliver medication painlessly, more regularly, and are manufactured without harsh chemicals.

Developed by a team from Tuft University, the microneedles are created by casting a drug-filled silk protein over a negative mold. The process can be completed at room temperature and normal pressure, and the resulting needle is bio-compatible.

The researchers also discovered that the application of tetracycline to the silk protein helped control the growth of the staph bacteria on the application site.
