Abstract

An efficient multi-functional platform with excellent modularity, extendability, reproducibility, and recyclability is designed to achieve both bacteria sensing and killing based on electron transfer (ET) between the bacteria and Au@ZnO. A linear relationship is observed between the bacteria saturation current and bacteria number on the semilogarithmic scale. The bacteria-materials interaction mechanism is different from photocatalysis, extracellular ROS, Zn2+ leaching, or related environmental changes, but rather relies on ET which also causes metabolic imbalance and subsequent bacterial death. The quantitative correlation and different interaction mechanism reveal a novel platform to render “sense-and-treat” devices feasible. The ET mechanism also provides insights into the design.
