An Enzyme Immobilized Mesh for Bio-fluorometric Acetone Gas-imaging Camera

Abstract

Human-derived acetone vapor could be utilized in clinical practice. In this paper, we prepared and demonstrated secondary alcohol dehydrogenase (S-ADH) immobilized mesh toward acetone vapor imaging. Immobilized S-ADH activity was evaluated by autofluorescence of reduced nicotinamide adenine dinucleotide which is consumed in S-ADH catalytic reaction with acetone. As a result, a glutaraldehyde crosslink method showed higher S-ADH activity and allowed fluorometric imaging of acetone vapor without distortions.
