<p>Forensic science is increasingly intersecting with the principles of nano physics, not only in the detection and analysis of trace evidence but also in understanding the mechanistic pathways through which nanometer-scale phenomena influence injury production in biological tissues. Traditional forensic biomechanics primarily explains how macroscopic forces disrupt anatomical structures. However, emerging evidence indicates that nanoscale physical interactions - including mechanotransduction, nanotoxicological effects, and quantum-scale surface phenomena - may contribute to the initiation, propagation, and interpretation of injuries encountered in forensic investigations. By synthesizing these fundamental nano-physical principles with established biochemical and biomechanical mechanisms of injury, this article explores the conceptual integration of nanoscience within forensic medicine and injury biomechanics. Such an approach may support the development of more refined frameworks for interpreting injury patterns and forensic evidence in future medico-legal practice.</p>
