Background: Fingerprints are the most important for personal identity. Latent fingerprints are those which is invisible through our naked eyes due to which it gained all the researchers attention. Fingerprint remains same right from birth till death. It starts developing in the fourth month of gestation and can be recovered, after death from a dead body. Main Body: In this topic we will explore invention and innovation in fingerprint development, being the most reliable for personal identification, helps in further forensic investigation. No two person has same fingerprint even identical twin sharing same DNA has different fingerprint. This area in forensic science is highly developed and many more such developments can be done. It is developed on various porous, non-porous surfaces through sebaceous secretion of skin, the oily matter gets deposit on the surface. Through the past research and review paper, it can be said that this topic is one of the most explored during forensic science, opened the doors for new researchers to works on it. Latent fingerprint development though powders is one of the physical method and powders used are expensive. These naturally occurring powder like sugar molasses, sugar, salt, turmeric, chilli, onion, etc powders to develop, this is easy and cost- effective way. Conclusion: The basic method through horse or squirrel brush was used in every method to spread powder evenly on the print without disturbing the print. Many works have been done on fingerprint development powders, but we can do an innovation on the brush, instead of horse or squirrel brush we can use some other animal brush like camel or some other material like fibre
