SUPPORT BACKING STRIP TECHNOLOGY AND METHOD FOR NON-DESTRUCTIVE IDENTIFICATION OF LATENT PRINT AND DNA DEPOSITED ON ADHESIVE MATERIALS

摘要

A method is provided for recovering a sample of DNA. The method includes providing a portion of adhesive tape having first and second opposing major surfaces, wherein said first major surface has an adhesive disposed thereon; applying a backing strip to the second major surface of the tape, thereby obtaining a mounted tape, wherein said backing strip has first and second opposing major surfaces, and wherein said first and second major surfaces of said backing strip are embossed; capturing a fingerprint on the first surface of the mounted tape, thereby obtaining a specimen, wherein said specimen contains DNA; winding the specimen into a helical configuration in which opposing surfaces of the adhesive tape are spaced apart from each other by said backing strip, thereby obtaining a wound specimen; placing the wound specimen in a receptacle; and extracting a sample of DNA from the wound specimen with a solvent.
