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.
