Researchers measure Low cost Turbidity using smartphone app

Continuous monitoring of bacterial growth is a critical step in the biotechnology industry and in biological labs. These measurements are typically taken using large and bulky spectrophotometers that do not fit into incubators for real-time monitoring. Moreover, continuous monitoring is labor-intensive as it requires multiple samplings. Recent developments by researchers from Cork, Ireland have overcome these challenges by hacking a generic heart rate monitor to make a low-cost turbidity tracker. The team 3D printed a holder where an LED light…
