INTRODUCTION
As we are in the modern era, we use distinct products in our dai-

ly life on various parts of the body. Due to the COVID (Coronavi-

rus Disease) pandemic, we started using sanitizers on our hands, and

the usage of various products such as lotion, creams and oils. Some

of these products could affect or deteriorate or degrade the original

fingerprints over time, and there is a probability of getting a chance

print (oil, sanitizer, lotion applied print) that suspects may use these
substances during their criminal conviction, making it difficult for the

forensic expert to identify a criminal due to the product properties.

Fingerprints are important and the best forms of physical and com-

monly used forensic evidence over DNA (Deoxyribonucleic acid) pro-

filing because of their uniqueness and are commonly used by forensic

scientists as reliable evidence.

AIM

To develop the latent fingerprint stained by oil, lotion, and sanitizer at

different intervals to identify the efficiency of the latent print.

METHODOLOGY

For this study, a control sweat print was taken both on porous and

non-porous surfaces, followed by a sweat print after application of oil,
lotion, and sanitiser each separately on both porous and non-porous

surfaces.
