Development Of Latent Fingerprint By Using Nanoparticles

A person can be recognised by its fingerprint impression. So, fingerprint plays a significant role in forensic science to connect crime with the criminal. There are three types of fingerprint namely patent, plastic and latent. Among which latent fingerprints are those which are invisible to unaided eyes but persist on surface for longer period of time, as they are unnoticeable by the criminal as well. Countless research studies have been going on till now to find out an alternative method for analysing latent fingerprint more profoundly. In twentieth century, nanotechnology specially in the field of forensic fingerprinting has change the view of detecting latent fingerprint. Therefore, this chapter presents an introduction to fingerprint notably on the latent fingerprint analysis with the advanced nanoparticles. A brief outline on the conventional techniques used for the analysis of latent fingerprint is described here. With this, a detailed description on the approach of using silver nanoparticle and calcium oxide nanoparticle for developing latent fingerprint is also presented in this chapter.
