Here we describe an optimized and efficient removal strategy for the collection of bio-particles present in ‘touch DNA’ samples, together with an enhanced amplification protocol involving a one-step 5 µl micro-volume lysis/STR amplification, to permit the recovery of short tandem repeat (STR) profiles of the bio-particle donor(s).
