Silk Sensor

First, you devise an implantable biosensor made of liquid silk and micropatterned gold.  The silk can conform to any tissue surface and the gold micropatterns are capable of detecting electromagnetic frequencies of various proteins that individually present a “terahertz signature.”  Add a transmitter device, and this assembly becomes an implantable antenna that signals biochemical signs and states.  Researchers at Tufts University, who have created this device, also have show that its message transmits through several layers of a pig’s muscle.       MORE
