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.
