Electrochemical Diagnostics for Bacterial Infectious Diseases
Amruta Karbelkar, Ariel L. Furst
Abstract
Bacterial infections are urgent threats to human health, especially in light of rising rates of antibiotic resistance, and their ubiquity demands the development of efficient diagnostic platforms. Electrochemical biosensors for point-of-care testing are garnering interest due to their speed, sensitivity, and selectivity as well as their inexpensive, user-friendly operation. These biosensors have the potential to make significant commercial and clinical impacts. In this Viewpoint, we discuss recent advances in the electrochemical detection of pathogenic bacteria using both direct and alternating current. We focus on platforms that detect whole microbes, as these sensors are specific, fast, and easy to operate.
