April 8, 2019 – Forensic Science International (FSI) Genetics published a study demonstrating selective trapping of sperm cells using rapid, automated, single-use microfluidic chips. The study, funded by the National Institute of Justice (NIJ) and conducted by the Landers Research Laboratory at the University of Virginia (UVA), used MicroGEM's forensicGEM™ Sperm to rapidly lyse sperm cells with no purification steps.

The prototype acoustic trapping technology, based on a multi-layer microfluidic device, isolated intact sperm cells from mock samples containing a 40-fold excess in female epithelial cells over sperm cells. Downstream PCR amplification resulted in male-only profiles.
