Vacuum Metal Deposition: Principle, Types & Components

Vacuum Metal Deposition VMD fingerprint development

Vacuum metal deposition (VMD) is probably one of the most sensitive fingermark detection and development techniques that are used in developing forensic fingerprint.  VMD is also capable of developing bloody fingerprints (you can check our article on “DEVELOPMENT OF BLOODY FINGERPRINTS“) for nonporous surfaces as well as semi-porous surfaces like woods and some fabrics. This …

Development of Bloody Fingerprints: Chemical Test and Techniques

Blood is one of the most common types of biological evidence that are encountered in violent crime scenes. And blood is one of the most commonly observed fingerprint contaminants and this fingerprint is called bloody fingerprints. Developing blood fingerprints may depend on the type of surfaces and also the types of environmental condition eg. rain. …
