A Tiny Sensor That Reads Creatinine in Seconds

Creatinine is a widely used marker of kidney function, but testing it still often depends on bulky instruments or methods prone to interference. This study presents a compact chemiresistive biosensor that directly transduces a biochemical reaction into an electrical signal. Built from platinum nanoparticles embedded in a polymer and coupled to an enzyme cascade, the device detects creatinine across a broad range and produces a response in about 35 seconds. Crucially, the sensor operates in a simple two-electrode configuration, eliminating the need for a reference electrode while maintaining high sensitivity.
