Abstract

We introduce an integrated microfluidic device consisting of a biomolecule concentrator, picoinjector and a micro droplet generator. We used this platform to detect ultra-low levels of matrix metalloproteinases (MMPs) from diluted cellular supernatant and showed that it significantly (∼10-fold) reduced the time required to complete the assay and the sample volume used. Biomolecule concentrator enhances the limited sensitivity of low-abundance enzyme assays by concentrating sample solutions, while droplet generator confines concentrated reactants into a pico-liter volume for sustained high sensitivity enzyme reaction as well as enabling multiplexed assays with a limited sample volume. We demonstrated to screen five different protease sensors simultaneously to indicate specific protease MMP-9 with high sensitivity.
