Nanotech and Document Security

Abstract

Being a multidisciplinary field, forensic science has greatly evolved over the previous decades. The recent advances in nanotechnology have opened new windows for forensic sciences as it offers cutting-edge methods for simplifying the laborious forensic analysis of the questioned documents. In this regard, various nanoparticles are most widely exploited and coupled with the traditional methods for resolving cases marked with forgery. These methods are now emerging to be the extensively used strategies for the future analysis of questioned documents to obtain the analytical, quantitative, as well as qualitative profile of the ink on real samples. This chapter thus explores the trending (traditional as well as novel nano-based) methods used so far in the questioned documents analysis.
