With the rapid unveiling of more evolved sensors which are ultra-small and implantable and can be lodged inside a person’s body, personalized medicine has made impressive strides. Such sensors can detect various health issues before they happen and also indicate the exercise suitable for an individual. Scientists are now trying to do just that – promote a range of family of devices. In fact, they have already started to market their device in Europe and are hoping for an approval of the technology in the U.S. as well.
The team of researchers who came up with the devices, presented their results at the 255th National Meeting & Exposition organized by the American Chemical Society.
Scientists Use Ultra-tiny Sensors to Carry Out Task
The new set of sensors steal a march over the other currently used implantable sensors by being immune to the fluids and other stuff inside it. The sensors used so far have been often seen to generate “foreign body” immune response which coats them with scar tissue or inflammatory cells. This can prevent contact of the device with the capillaries and hence thwart it from detecting chemical changes properly. So much so, it stops functioning in a couple of weeks or months’ time.
The group of scientists overcame the challenge by making the sensors ultra-tiny – even smaller than a grain of rice. They also used hydrogel scaffold to make it, which is highly flexible like a contact lens. As a result the body failed to identify the sensors as foreign objects.
