A novel, integrated forensic microdevice on a rotation-driven platform: Buccal swab to STR product in less than 2 h.

This work describes the development of a novel microdevice for forensic DNA processing of reference swabs. This microdevice incorporates an enzyme-based assay for DNA preparation, which allows for faster processing times and reduced sample handling. Infrared-mediated PCR (IR-PCR) is used for STR amplification using a custom reaction mixture, allowing for amplification of STR loci in 45 min while circumventing the limitations of traditional block thermocyclers.
