A new ultrasensitive medical imaging technique developed at Purdue University uses a pulsed laser and tiny metallic "nanocages" to enable both the early detection and treatment of disease. The system works by shining near-infrared laser pulses through the skin to detect hollow nanocages and solid nanoparticles that are injected into the bloodstream.

TOUCH-FREE WIRELESS SENSING UC San Diego electrical engineering PhD student Yu Mike Chi has developed a wireless sensor that records "biopotentials" - tiny voltage signals that appear on the skin surface - without touching the skin. Biopotentials emanate from electrically active cells, such as neurons and cardiac cells, and propagate through the conductive media of the human body.

University of Florida engineers have developed a prototype of a "tattletale pill" by adding a tiny microchip and digestible antenna to a standard pill capsule. The prototype opens up the possibility that mass-produced pills will someday be equipped to inform doctors and loved ones that patients have ingested their medication.

A team of researchers from Rensselaer Polytechnic Institute will send an army of microorganisms into space to investigate new ways of preventing the formation and spread of biofilms - or clusters of bacteria - that could pose a threat to the health of astronauts.

The field of biosensors may be getting a boost from an unlikely source: coffee rings. UCLA researchers are studying the "coffee ring" phenomenon - the observation that many liquids, when spilled, evaporate to leave a darker ring around the perimeter that contains a much higher concentration of particles than the center. A better understanding of how these rings behave at the micro- and nano-scale would help provide guidance for the development of more advanced biosensors.

Researchers at Ohio State University have developed a way to enhance how brain tumors appear in MRI scans and during surgery, making the tumors easier for surgeons to identify and remove.
