Integrated Microfluidic System for Rapid DNA Fingerprint Analysis: A Miniaturized Integrated DNA Analysis System (MiDAS)-Swab Sample-In to DNA Profile-Out.

Abstract

A fully automated rapid DNA analysis system requires integrating several operational elements performing multiple steps onto one single microfluidic platform. The functions to include on the microfluidic platform consist of substrate lysis, lysate DNA extraction, single or multiplexed PCR amplification, amplicon separation, and product readout. Here we describe a fully automated integrated system for forensic short tandem repeat (STR) analysis of reference samples, achieving buccal swab-in and DNA profile-out.
