Bacterial catalase-responsive colorimetric array driven by nanozyme cascade for pathogen identification and phenotypic susceptibility testing.
The rapid discrimination of bacterial species and assessment of their antibiotic susceptibility are critical for combating antimicrobial resistance. Herein, we report a metabolism-driven colorimetric sensor array based on bacterial catalase-responsive hydrogen peroxide (H2O2) consumption coupled with an Au@PB (gold-coa...
