Ultra-sensitive trace detection
The hollow cauliflower-like hierarchical structure with uniformly loaded PdAg bimetallic catalysts, fabricated via surface modification engineering, enhances 3H2B adsorption energy and electron transfer, lowers operating temperature to 180 °C, enabling ultra-sensitive detection of Listeria monocytogenes metabolic biomarkers.
