Development of a nanocomposite chemiresistor sensor based on Π-conjugated azo polymer and graphene blend for detection of dissolved oxygen
(2018-10-15)
The present paper describes the electrochemical impedance activity of a hybrid film with graphene and poly(azo-Bismarck Brown Y) as the chemiresistor material. This nanocomposite film exhibits interesting properties based ...
Synergistic effect of reduced graphene oxide/azo-polymer layers on electrochemical performance and application as nonenzymatic chemiresistor sensors for detecting superoxide anion radicals
(2019-11-01)
The present paper describes a nonenzymatic chemiresistor sensor based on an azo-polymer and reduced graphene oxide (rGO) as a resistive platform for superoxide radical detection. The sensorial platform was prepared on ...
Chemiresistor Arrays Prepared by Simple and Fast Vapor-Phase Thiol Place-Exchange Functionalization of Gold Monolayer-Protected Cluster Films
(Wiley-VCH, 2016-08)
We describe a simple, versatile, and relatively fast method to alter the sensor selectivity of chemiresistors based on films of Au monolayer-protected clusters (MPCs) by varying their functionalization via vapor-phase thiol ...
A chemiresistor sensor based on a cobalt(salen) metallopolymer for dissolved molecular oxygen
