The primary objective of forensic investigation of a case is to recognize, identify, locate, and examine the evidence. Microscopy is a technique that provides crucial information for resolving a case or advancing the investigation process by analyzing the evidence obtained from a crime scene. It is often used in conjunction with suitable analytical techniques. Various microscopes are employed; scanning probe microscopes are available in diverse forensic analyses and studies. Among these, the atomic force microscope (AFM) is the most commonly used scanning probe technology, offering a unique morphological and physico-chemical perspective for analyzing multiple pieces of evidence in forensic investigations. Notably, it is a non-destructive technique capable of operating in liquid or air without complex sample preparation. The article delves into a detailed exploration of the applications of AFM in the realms of nanomechanical forensics and nanoscale characterization of forensically significant samples.
案例法医调查的主要目的是识别、鉴定、定位和检查证据。显微镜技术是一种通过分析从犯罪现场获得的证据来提供解决案件或推进调查过程所需关键信息的技术。它通常与合适的分析技术结合使用。各种显微镜都有应用；扫描探针显微镜在各种法医分析和研究中都有应用。其中，原子力显微镜（AFM）是最常用的扫描探针技术，为法医调查中分析多种证据提供了独特的形态和物理化学视角。值得注意的是，它是一种非破坏性技术，能够在无需复杂样品制备的情况下在液体或空气中运行。本文深入探讨了 AFM 在纳米机械法医和法医有意义样本的纳米级特征化领域的应用。
