International Activities in Nano-Forensics

Introduction

Nanotechnology is a branch of science, with important applications in a variety of other fields. Nanotechnology also has a important impact on forensic science. Nano-forensics is the use of nanotechnology-based methods to solve forensic science cases. (Kumar & Sharma, 2021). This is known as Nano-forensics, and it is the most recent advancement in the field of forensic science. Nanotechnology aids technology that deals with nanometer-sized matters. The term “nanoparticle” is typically applied to inorganic materials opposed to single molecules. Ultrafine particles are the same as nanoparticles and range between 1 and 100 nm in size, whereas fine particles range between 100 and 2,500 nm, and coarse particles range between 2,500 and 10,000 nm. (Brayner et al., 2012). There are many ways to make nanoparticles, including chemical, physical, and biological processes. While the chemical technique of synthesis only requires a little time to produce a high number of nanoparticles, this method requires capping agents to maintain the size of the nanoparticles. Nanoparticle production and stabilisation chemicals are toxic and produce byproducts that are bad for the environment. The demand for green nanotechnology is driven by the need for environmentally safe, non-toxic synthetic processes for the manufacture of nanoparticles. (Bar et al., 2009).

Nanoparticles put forward fundamentally advantageous platform, validating unique properties with potentially wide-ranging application (Murray, Kagan, & Bawendi, 2000). Many research teams have using biological systems for the synthesis of nanoparticles due to the numerous advantages they offer over non-biological systems. Due to a number of reasons, comprising their similar size to biomolecules like proteins and poly nucleic acids, nanoparticles have unique capabilities and are useful (Akhlaghi,Peng, Yao, & Tam, 2013).
