Performance of the Nanobio-Based Reagent for Visualising Wet Fingerprints Exposed to Different Levels of Water Salinity

Introduction: Recovery of evidence such as murder weapons in waterways has been commonly reported. However, visualising latent fingerprints on the immersed substrates may prove challenging due to its obliteration by physicochemical parameters (e.g. pH, temperature, salinity) well mechanical effect water. Although use Small Particle Reagent (SPR) for wet non-porous suggested, it contains molybdenum and titanium that are toxic, their utilisation must be reduced. Furthermore, no study verifies chemical and/or physical interaction between SPR lipid constituents leads visualisation ridge details. Methods: The newly developed nanobio based reagent (NBR) i.e. Candida rugosa lipase-multiwalled carbon nanotubes (CRL-MWCNTs) were used glass slides water with salinitylevels representing those estuary swimming pool up 15 days. Results: It was observed quality visualised using NBR comparable SPR. Characterisations via instrument bioinformatics analyses have also verified incorporation CRL onto MWCNTs fingerprints. Conclusions: Therefore, a promising relatively greener alternative substituting different levels salinity.
