The effect of DNA recovery on the subsequent quality of latent fingermarks

Highlights • The effects of five DNA recovery methods on fingermark quality were investigated. • Flocked swabs and gel lifts were generally the least destructive DNA methods. • Dry swabs were less destructive on textured and porous surfaces. • Wet swabbing and tape lifting were very damaging methods...

Description
Summary:Highlights • The effects of five DNA recovery methods on fingermark quality were investigated. • Flocked swabs and gel lifts were generally the least destructive DNA methods. • Dry swabs were less destructive on textured and porous surfaces. • Wet swabbing and tape lifting were very damaging methods of DNA recovery. • All of the DNA recovery methods reduced the quality of latent fingermarks on glass
