Rapid antimicrobial susceptibility testing using carbon screen printed electrodes in a microfluidic device
A novel method for rapid, sensitive, and affordable antimicrobial susceptibility testing (AST) is introduced using a diluted low-conductivity nutrient medium. The device uses low-cost carbon screen-printed electrodes and a simple microfluidic geometry. The method detects bacteria even at a low density of 84/mm2 in three hours. The system enhances accessibility and affordability, making it a critical checkpoint for antimicrobial resistance threats.
