    Abstract

    This study presents a number of pseudo-operational trials on plastic bags investigating the double and co-fuming process of a one-step fluorescent cyanoacrylate (LumicyanoTM) with comparisons to the two-step process with basic yellow 40 (BY40) staining for the detection of latent fingermarks. The results demonstrate that both the Lumicyano solution and dye contribute to the increased detection of latent fingermarks during the double fuming process (trial 1). Co-fuming the Lumicyano solution and dye separately (at a concentration of 8%) but simultaneously was less effective than 8% Lumicyano (trial 2). Co-fuming Lumicyano 8% and an additional 8% Lumicyano dye by weight was more effective than Lumicyano 8% (trial 3), possibly due to increased fluorescent material deposition during co-fuming allowing for better visualisation. The use of BY40 after Lumicyano resulted in a considerable increase of detected fingermarks.
