ABSTRACT = {The objective of this research work is to investigate the feasibility of fabricating bio-based
visual sensor indicators to detect the presence of H<sub>2</sub>S using inkjet printing. Myoglobin and
chitosan were used as indicating and immobilizing materials respectively. 30 mg of myoglobin
dissolved in 1 mL of tris buffer with 10% glycerol gave optimum jettability properties. Similarly,
drop formation was optimal for 0.50% m/v chitosan solution diluted to 10 cP viscosity. The
samples were fabricated in layer-by-layer approach and indicator with 2 layers of chitosan and 4
layers of myoglobin gave maximum sensitivity with 14.42 for 0.7 mg/L of H<sub>2</sub>S. The sensors
retained their functionality for 5 days even when stored at room temperature.},
