Ultrahigh-sensitivity label-free single mode-tapered multimode-single mode fiber U-shaped biosensor for Staphylococcus aureus detection

Shi Qiu et al.

Summary: This paper presents a fast (<20 mins), label-free biosensor using a U-shaped single mode-tapered multimode-single mode (STMS) fiber structure for rapid detection of Staphylococcus aureus (S. aureus) at very low concentrations. The biosensor showed an average wavelength shift of 1.552 nm when immersed in an S. aureus sample with a concentration of 4 cells/mL, and a dip wavelength shift of 0.348 nm when the S. aureus concentration was further diluted to 0.4 cells/mL, confirming its ability to detect single colonies of S. aureus. The variation in the average wavelength shift for S. aureus concentrations from 4 to 4 × 103 cells/mL was found to be -21% in milk and lettuce samples.
