Salmonella typhimurium detector based on the intrinsic peroxidase-like activity and photothermal effect of MoS2

Rapid detection of Salmonella in food matrices by photonic PCR based on the photothermal effect of Fe3O4

“…Bacteria were cultured as same as literature with slight modifications, pure bacterial colonies were cultured in NB liquid medium overnight at 37℃, 200 rpm ( Du et al, 2019 , Du et al, 2020 , Lu et al, 2022 ). The concentration of Salmonella typhimurium was calculated by the classical plate colony counting method.…”

Rapid detection of Salmonella using an aptamer-functionalized PDA liposome sensor with naked-eye colorimetric sensing

“…These results indicate that the limit of detection (LOD) for Salmonella on the prepared PDA liposome-aptamer sensor is 1 Â 10 3 CFU mL À1 , which is comparable to the lowest value of the visual detection limit in a previously reported study on Salmonella detection sensors. 42,43 The detection capability of the PDA liposome sensor is highly significant as it enables the naked-eye identification of Salmonella at concentrations above 1 Â 10 3 CFU mL À1 , which is reported as a human health hazard, 44 within a rapid timeframe of 15 minutes.…”

Overview of Rapid Detection Methods for Salmonella in Foods: Progress and Challenges

“…When some nanomaterials are irradiated by photon energy with different wavelengths, the vibration inside the atom converts light energy into heat energy, resulting in a photothermal effect, and this is the cornerstone of photothermal detection [97]. Common nanomaterials such as Au NPs, graphene oxide, black phosphorus, molybdenum disulfide and Prussian blue are used in photothermal detection frequently [98][99][100][101][102].…”
