Digital Counter: A Microfluidics and Computer Vision-Based DNAzyme Method for the Isolation and Specific Detection of from Water Samples.

Biological water contamination detection-based assays are essential to test water quality; however, these assays are prone to false-positive results and inaccuracies, are time-consuming, and use complicated procedures to test large water samples. Herein, we show a simple detection and counting method for in the water samples involving a combination of DNAzyme sensor, microfluidics, and computer vision strategies. We first isolated into individual droplets containing a DNAzyme mixture using droplet microfluidics.
