About
Mingzhang Guo is a leading figure in biosensor development, with a primary focus on ultrasensitive detection methods for foodborne pathogens. His research integrates DNAzyme technology, metal nanoclusters, and signal amplification strategies to create innovative fluorescent biosensors. Guo’s most cited work, "Ultrasensitive magnetic DNAzyme-copper nanoclusters fluorescent biosensor with triple amplification for the visual detection of E. coli O157:H7" (2020, 82 citations), exemplifies his contribution to rapid, visual pathogen screening. This paper introduces a triple amplification mechanism—combining magnetic separation, DNAzyme catalysis, and copper nanocluster fluorescence—to achieve exceptional sensitivity and simplicity. The method enables naked-eye detection of E. coli O157:H7, a major cause of foodborne illness, addressing critical needs in food safety and clinical diagnostics. Guo’s work has garnered significant attention, with this study alone accumulating over 80 citations, reflecting its impact on analytical chemistry and biosensing. His achievements include advancing point-of-care testing through cost-effective, equipment-free visual readouts, making pathogen detection accessible in resource-limited settings. For students and researchers, Guo’s research exemplifies how interdisciplinary approaches—merging nanotechnology, biochemistry, and engineering—can solve real-world challenges in public health and food safety.
