Query: Scalable, Non-Invasive Glucose Sensor Based on Boronic Acid
  Functionalized Carbon Nanotube Transistors   We developed a scalable, label-free all-electronic sensor for D-glucose based
on a carbon nanotube transistor functionalized with pyrene-1-boronic acid. This
sensor responds to glucose in the range 1 uM - 100 mM, which includes typical
glucose concentrations in human blood and saliva. Control experiments establish
that functionalization with the boronic acid provides high sensitivity and
selectivity for glucose. The devices show better sensitivity than commercial
blood glucose meters and could represent a general strategy to bloodless
glucose monitoring by detecting low concentrations of glucose in saliva.
