Скачать или смотреть Fingerprint Development Methods: Physical vs. Chemical Techniques in Forensics

​Uncover the essential forensic science techniques used to make latent fingerprints visible for analysis! This video, presented by Visakha Tripathi from the Forensic Science Academy (FSA), provides a deep dive into the Physical and Chemical Methods for fingerprint development, including their pros, cons, and best practices.
​🔍 What You'll Learn in This Video:
​Introduction to Fingerprints: Why fingerprints are considered one of the most reliable forms of forensic evidence—and the crucial role of development techniques.
​Classification of Methods: A clear breakdown of Conventional and Non-Conventional development techniques.
​🔬 Physical Methods (Particle Adhesion):
​Detailed look at Powder Dusting and Magnetic Powder methods.
​Understand their application on non-porous surfaces, and their specific advantages (quick, non-destructive) and limitations (smudging, poor results on porous surfaces).
​🧪 Chemical Methods (Residue Reaction):
​In-depth explanation of Ninhydrin Method for developing prints on porous materials like paper (reacts with amino acids).
​The Cyanoacrylate Fuming (Superglue) method and its use on glass, metal, and plastic.
​Overview of Silver Nitrate, Iodine Fuming, and DFO (an alternative to Ninhydrin).
​Conclusion: Why no single method is perfect, and the importance of applying a combination of techniques based on the surface type and environment.
