We present a fast method to monitor hydrogen sulfide (H2S) in ambient air based on a visible color change. Therefore, an immobilized copper(II) complex of the azo dye 1-(2-pyridylazo)-2-naphtol (H-PAN) was synthesized and prepared in a matrix for screen printing. Different materials, reaching from opaque paper to transparent foils served as substrate. The reaction of the copper(II) complex (Cu-PAN) to the target gas H2S was measured in reflection via UV/VIS spectroscopy.

Fluorosurfactant functionalized gold nanorods can act as selective colorimetric nanoprobes for H2S. These proposed nanoprobes can accurately detect biological H2S in human and mouse serum samples as well evaluate the activity of H2S synthetase.
