New Staphylococcus aureus Findings from Indian Institute of Technology Guwahati Described (Highly sensitive and selective optical detection of Staphylococcus aureus using thiol functionalized monolayer tungsten disulfide grown by chemical vapor...).

Researchers at the Indian Institute of Technology Guwahati have developed a highly sensitive and selective optical detection method for Staphylococcus aureus using thiol functionalized monolayer tungsten disulfide. The method utilizes the photoluminescence emission of 1L-WS2 to recognize and detect S. aureus bacteria with high sensitivity and selectivity. This innovative sensing system shows promise for future applications in optical biosensing of pathogenic species, offering a lower detection limit of 2.0 CFU/mL and 78% accuracy in identifying S. aureus in human urine at a concentration of 105 CFU/mL.
