Silk Optical Implant Treated with the Cancer-Fighting Drug Doxorubicin (image) Tufts University Share Print E-Mail Caption This is a microscopic image of a silk optical implant treated with the cancer fighting drug doxorubicin. When implanted in tissue, the mirror released a controlled dosage of the drug as it gradually dissolved. The amount of reflected light decreased as the mirror degraded, allowing the researchers to accurately assess the rate of drug delivery.
