MIT: Biomedical
devices that can be implanted in the body for drug delivery, tissue
engineering, or sensing can help improve treatment for many diseases.
However, such devices are often susceptible to attack by the immune
system, which can render them useless. A team of MIT researchers has come up with a way to reduce that
immune-system rejection. In a study appearing in the May 18 issue of
Nature Materials, they found that the geometry of implantable devices has a significant impact on how well the body will tolerate them.
