Abstract
Ultrafast and sensitive detection of Staphylococcus aureus , a harmful Gram-positive human pathogenic bacterium, by two-dimensional layered materials continues to be a challenge. Here we present an ultrafast and selective detection of S. aureus bacterium using strong fluorescence emission of WS 2 QDs.
