STAR Protocols (Jun 2023)
A protocol to execute a lab-on-chip platform for simultaneous culture and electrochemical detection of bacteria
Abstract
Summary: Here, we present a protocol for a miniaturized microfluidic device that enables quantitative tracking of bacterial growth. We describe steps for fabricating a screen-printed electrode, a laser-induced graphene heater, and a microfluidic device with its integrations. We then detail the electrochemical detection of bacteria using a microfluidic fuel cell. The laser-induced graphene heater provides the temperature for the bacterial culture, and metabolic activity is recognized using a bacterial fuel cell.Please see Srikanth et al.1 for comprehensive information on the application and execution of this protocol. : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
