Paper Title
To Study The Release of Nanomaterial From Nano Paint Samples for Forensic Purpose

Paint can be used as evidence for different types of cases such as hit-run and automobile crashes. Forensic examination of this evidence material is carried out to link the suspect vehicle to the scene of crime or involvement of vehicles in the crashes. Nowadays, nanoparticle-coated paints are available for different surfaces to get improved properties like self-cleaning, UV protective, Antibacterial, etc. Fourier-transform infrared spectroscopy (FTIR), Ultraviolet-visible spectroscopy (UV), and XRF are used for studying the paint in comparative examination inforensic science along with the simple chemical testing, and examination under a microscope. But for the analysis of nano-coated paint samples requires expensive equipment like Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), X-Ray Diffraction (XRD), Atomic force microscopy (AFM). To operate these equipment’s there is a need for highly technical persons.In the present work, we have performed the electrochemical measurements of the sample of TiO2 nanoparticlecoated paint and the sample of paint without coating. It was observed that due to the release of nanoparticles from thenanocoated paint higher current was generated in comparison tothenon-coated paint sample and differentiated the nano-coated sample with non coated. The study shows that this is a less expensive technique, low cost, and user-friendly. It can be considered as a good technique for comparative examination of TiO2 nanoparticle-coated paint flakes and without paint flakesbased on the current generated in the electrochemical cell to establish the source of origin.
