Effect of hand sanitizer on the performance of fingermark detection techniques

Highlights • Investigation into the effect of hand sanitizer on fingermark detection techniques. • Alcoholic hand sanitizers found to have no effect on common development techniques. • Non-alcoholic hand sanitizers lead to an observable increase in development quality when using amino acid reagents....

Description
Summary:Highlights • Investigation into the effect of hand sanitizer on fingermark detection techniques. • Alcoholic hand sanitizers found to have no effect on common development techniques. • Non-alcoholic hand sanitizers lead to an observable increase in development quality when using amino acid reagents. • Increased development potentially due to the active ingredient in non-alcoholic hand sanitizers − benzalkonium chloride.
