Fluorescence properties of MSP. Fluorescence properties of MSP. (A) Fluorescence emission spectra of MSP-0h, MSP-6h, MSP-24h, and MSP-72h (all 100 μg/ml) in DI water. (B) Fluorescence intensity of MSP-72h (100 μg/ml) versus illumination time at 660-nm emission. (C) Fluorescence emission spectra of MSP-72h (100 μg/ml) in solutions of different solvents and pH values. (D) Fluorescence intensity, (E) FWMH, and (F) wavelength of the emission peak for MSP-72h samples with varied concentration in solutions of different solvents and pH values. All fluorescent signals were recorded using a Hitachi F-7000 Fluorescence Spectrophotometer with an excitation wavelength of 552 nm. Xiaohui Yan et al. Sci.
