Implantable Device for Monitoring Cancer and Biomarkers Developed

MIT researchers have developed a device, right, that can be implanted into a tumor to monitor how it responds to treatment

MIT, Boston General Hospital and other researchers have developed an implantable device for monitoring cancer.

An implantable diagnostic device that senses the local in vivo environment. This device, which could be left behind during biopsy, uses a semi-permeable membrane to contain nanoparticle magnetic relaxation switches. A cell line secreting a model cancer biomarker produced ectopic tumors in mice.

Short term applications for this device are numerous, including verification of successful tumor resection. This may represent the first continuous monitoring device for soluble cancer biomarkers in vivo.
MIT has an article on this from May 2009.
