Odorant Binding Proteins and Porphyrins Mixed Gas Sensor Array

Abstract

A hybrid array made of biosensors and chemical sensors is introduced as a functional electronic nose. Quartz Microbalance sensors are functionalized with odorant binding proteins from Anopheles Gambiae and metalloporphyrins. The results indicate a complementary role of both sensor technologies demonstrated by the complete identification of a set of similar VOCs independently from their concentrations.
