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 μM–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…

Selective sensing of ethylene and glucose using carbon-nanotube-based sensors: an ab initio investigation.

A clear atomistic picture emerges about the mechanisms involved in glucose and ethylene sensing: semiconducting nanotubes exhibit good sensitivities in both cases, and the current through metallic nanot tubes is only weakly affected by analyte attachment.

This work presents an elucidation of the electronic biosensing mechanisms with a newly developed microarray of nanotube "micromat" sensors and reveals that electronic effects occurring at the metal-nanotube contacts due to protein adsorption constitute a more significant contribution to the Electronic biosensing signal than adsorbed solely along the exposed lengths of the nanotubes.

Boronic acid library for selective, reversible near-infrared fluorescence quenching of surfactant suspended single-walled carbon nanotubes in response to glucose.

High-throughput screening of a library of 30 boronic acid derivatives to form complexes with sodium cholate suspended single-walled carbon nanotubes to screen for their ability to reversibly report glucose binding via a change in SWNT fluorescence finds that glucose recognition and transduction is enabled by para-substituted, electron-withdrawing phenyl boronics acids that are sufficiently hydrophobic to adsorb to the nanotube surface.
