Abstract: A method for developing and enhancing a latent fingerprint on a surface, method comprising: i) depositing or providing a latent fingerprint on the surface, ii) subjecting the latent fingerprint to cyanoacrylate fuming to form a polymerized cyanoacrylate ridge pattern corresponding to fingerprint residues, iii) cooling surface after cyanoacrylate fuming and applying a curcumin reagent to the cyanoacrylate-developed fingerprint followed by drying, iv) applying a bromothymol blue reagent to curcumin-treated fingerprint followed by drying and v) visualizing the resulting fingerprint based on enhanced ridge clarity and contrast. The developed fingerprint is evaluated based on one or more parameters selected from ridge clarity, contrast, ridge continuity, stability and overall fingerprint quality. In the method, the cyanoacrylate fuming, curcumin treatment and bromothymol blur treatment collectively provide enhanced ridge-background differentiation compared with cyanoacrylate fuming alone and curcumin treatment provides fluorescence enhancement of cyanoacrylate-developed fingerprint and bromothymol blue treatment provides colour-contrast enhancement of fingerprint.
