Biosensors to Tell You When You're Gonna Fall Sick

Very similar to the "check engine" light in your car, scientists are coming up with biosensors which when implanted in your body could signal to you when you're falling sick.

One such medical device that's heading for clinical trials, perhaps later in 2011 is a robotic arm that moves almost like a natural arm.

Proteins can be Detected by Carbon Nanotubes Form Ultrasensitive Biosensor
Study says carbon nanotubes coated with a thin layer of protein-recognizing polymer form a biosensor capable of using electrochemical signals to detect minute amounts of proteins

It works to a control system that monitors brain activity via a biosensor implanted on the surface of a patient's brain. That project aims to provide better artificial arms for wounded soldiers.

Scientists and medical device regulators are working together to fast track approval of such "biosensors" and devices.

Biosensors monitor changes in the body, often "disease markers" - proteins, genes and other biochemical substances involved in health and disease. And they raise a red flag when things go awry.

Study Says Coffee Ring may Help Biosensors Detect Disease
If you have a habit of observing coffee rings, you can also observe that the spot has a darker ring around its perimeter that contains a much higher concentration of particles than the center.

The study appeared in the current edition of Chemical and Engineering News (C and EN).
