University of Arkansas researchers have tested a new bio sensor which can detect glucose in real time and with greater sensitivity as compared to biocompatible sensors. Called the UA sensor, it has been developed by Xie and has been created with multi-walled carbon nanotubes with a coating of platinum nanoparticles which are one to five nanometers in diameter. These sensors were tested with and without nanoparticles and in this case the carbon nanotubes with platinum were found out to have higher level of sensitivity as compared even without platinum.
Xie stated:
At this stage of the research, we believe that the improved electro-chemical performance is due to the platinum nanoparticles. We are currently investigating mechanisms to optimize this performance.
Since the sensor has a response time between fifteen and thirty seconds it can offer glucose screenings in real time. The improved sensibility was attributed to platinum in multi walled nanotubes.
