A novel polymer poly (6-O-MMAGlc) has been synthesized via free radical polymerization of monomer methyl 6-O-methacryloyl-α-D-glucoside (6-O-MMAGlc) and characterized. The influence of poly(6-O-MMAGlc) on the formation of hen egg white lysozyme (HEWL) amyloid fibril was detailly investigated, indicating that the polymer could effectively inhibit the formation of HEWL amyloid fibril. The formation kinetics of HEWL amyloid fibril with the presence of poly(6-O-MMAGlc) was measured by Thioflavin T (ThT) fluorescence method, demonstrating that poly(6-O-MMAGlc) could significantly inhibit the amyloid fibril formation of HEWL in a dose-dependent manner.

The proposed FTMI is applied to measure temperature and refractive index (RI). A high temperature sensitivity of 118.

By fusion-splicing, the taper diameter-length ratio is around 1:1, which is much greater than those (1:10) made by stretching. The proposed fabrication method is very low cost, 1/20-1/50 of those of LPFG pair MZI sensors.
