Abstract

Nanotechnology, on its part, is at the cutting edge in forensic science and leading the revolution of approaches groundbreaking in crime investigation. This paper has been researched in an intense manner so as to discover the wide range of applications that nanotechnology has accrued within the domain of forensic analysis. These range from important spheres, including questioned documents examination, bloodstain ageing and estimation of post-mortem interval, as well as DNA profiling, explosive detection and identification of illicit drugs. With nanotechnologically based approaches, the efficiency and precision of forensic instruments are therefore dramatically increased, thereby proving that credible results can be provided within a significantly lesser amount of time. Remarkably, the discovery of graphene an exclusive two-dimensional carbon material, well known for its unequaled qualities by any other material is but a great potential. Capabilities of graphene come to the fore in bio-sensing, at levels of sensitivity and accuracy particularly for DNA detection that can be described as never seen before, due to its unique characteristics. In turn, this means that the general potential of nanotechnology carries its repercussions for the development of forensic analysis, both in its effectiveness and in its progress. It gives the researcher revolutionary instruments that enable him to solve riddles and make definite and reliable judgments, shaping a future where forensic science leads to more clarity and a sort of justice that finds no parallel.
