Advanced technology is helping meet the increasing demands of homeland security and drug cases.Ilene SemiatinThe field of forensic microscopy is more than a century old. Though practitioners say their profession is far less glamorous than its portrayal in popular TV crime and courtroom shows, forensic investigation remains a powerful tool for learning the truth about who may have committed various actions, where they occurred, and what tools or substances may have been used. Because almost all trace evidence is reviewed under a microscope at some point, techniques such as stereomicroscopy, polarized light microscopy and scanning electron microscopy (SEM) have become essential tools of...Read full articleRelated content from Photonics MediaARTICLESAdvancements in Raman Spectroscopy Find Real-World Uses in the Life SciencesSince its development in the mid-1920s, Raman spectroscopy has been used to study various low-frequency vibrational modes in molecular systems.
