Nanotechnology is a new discipline of research that has many advances. Due to their properties, nanostructures are involved in revealing many pieces of evidence and cases. Nanostructures play an important part in forensic study and criminology. It is evident that gold and silver nanostructures are greatly used in fingerprint detection. However different nano techniques are employed to detect trace materials from the crime scene. Fragmentation of DNA, amplification, and cooperation are taken place by using nanoparticles with the help of the PCR technique. Nanostructures can act as sensors for a variety of chemical and biological components, including explosives, according to contemporary studies on nanomaterial research and development. Nano-gold (Au-NPs), nano-silver, and nano-titanium dioxide (TiO2) particles along with capillary electrophoresis, SEM, TEM, and FTIR are used in forensic toxicology. Inculcation of nanostructures in saliva and nerve agent detection is also observed. In the realm of forensic science, nanotechnology is projected to play a significant role in the future by bringing more specialized and sensitive methods of case detection and revelation, as well as flawless evidence. In this review article, all the aspects where nanostructures are applied in forensic sciences are studied in detail.

“…[8][9][10][11] The development of latent fingerprints involves the usage of any physical or chemical means to make them visible and hence for this purpose, several techniques have been devised. [12][13][14][15] Physical methods involving powder, are the most widely used technique for latent fingerprint development since they are easy to use and also give quick and efficient results. [16][17][18] Nanotechnology also plays a significant role in forensic science and has remarkably proven successful in developing latent fingerprints.…”

Since waste materials are used to identify, individualize, and evaluate evidence like fingerprints, palmprints, footprints, etc. that are found at a crime scene, they have a substantial impact on the field of forensic science. Many waste powders have recently been employed in fingerprint recognition. Nanosheets made up of eggshells have been put forward as an application in friction ridge development. Eggshell is a biochemical substance made up of chemical compounds like calcium carbonate, which is considered as a waste product. For the formation of an eggshell nanosheet (ESN), shells are dried and crushed into a fine powder and to get this powder in the form of a nanosheet, the Ball milling technique is used. The synthesis of pure ESN is confirmed by Scanning Electron Microscopy (SEM) and X‐ray diffraction (XRD) techniques. The size of nanosheets ranged from 30 to 90 nm as shown in SEM images. Developed powder is then used for the application of fingerprint development and it provides excellent results on all porous, non‐porous, and semi‐porous surfaces. Thus, this newly synthesized ESN powder can be used as a significant powder method in latent fingerprint technology.
