Abstract:
We proposed a fast and temperature self-compensation method to detect streptomycin sulfate aqueous solution concentration based on a 2D Nb2CTX MXene nanosheets functionalized tilted Bragg grating(N-TFBG). The in-troduction of 2D Nb2CTX MXene nanosheets brought more than 100% increase in sensitivity and exhibited a high sensitivity of 253.8 pm/mg/mL and detection limit 80 µg/mL in range of 0.2-0.8 mg/mL. Due to high sensi-tivity and compact structure, N-TFBG sensor has a faster measure time than previous method; additionally, the sensor has simultaneous temperature measurement by detecting the cladding mode and the core mode resonance peak simultaneously. Our research will hopefully open a new research platform for online detection of strepto-mycin sulfate concentration.
