Evaluation of microFLOQ™ Direct Swab for Touch DNA Recovery

Abstract

This study evaluates the efficacy of the microFLOQ™ Direct Swab for touch DNA recovery from various surfaces within an office environment. Samples were collected using the swab and subjected to direct amplification with the GlobalFiler™ PCR Kit. Results revealed a success rate of 73% within three hours post-sample collection, with profiles ranging from full single to partial mixture. Despite observed artifacts, such as split and shoulder peaks, the swab demonstrated potential for efficient touch DNA recovery. However, further research is needed to assess its performance across diverse surfaces and to address challenges associated with artifact generation. Overall, the microFLOQ™ Direct Swab shows promise as a valuable tool for forensic touch DNA analysis, offering streamlined sample processing and potential advancements in forensic casework.
