Researcher reveals new way to safeguard DNA samples

DNA Profile from knife(Phys.org) —DNA evidence is invisible and remarkably easy to transfer, making it possible for a sample to be spilled or even planted on a piece of evidence.
Boise State University professor Greg Hampikian is known internationally for his work in DNA forensics, and he has developed a solution that permanently marks DNA samples to prevent contamination. Hampikian has used nullomers, the smallest DNA sequences that are absent from nature, to create the DNA bar code.
