Abstract
The rapid, simple, and reliable identification of the most prevalent pathogens is essential for clinical diagnostics, biology, and food safety. Herein, four protein‐encapsulated gold nanoclusters (protein–AuNCs) are designed and prepared as a sensor array for rapid identification of bacteria. The discrimination of six kinds of bacteria, including two kinds of drug‐resistant bacteria, is successfully realized by the as‐fabricated sensor array. The strategy presented here shows the advantages of easy synthesis and convenient to use. Furthermore, 100% classification accuracy is achieved by the sensor array consisting of two protein–AuNCs probes, demonstrating the design with sufficient diagnostic capacity. Taken together, the developed sensor array holds great promise for facile diagnosis of bacterial infection in resource‐limited settings.
