WGM laser spectra of the LC-amplified optofluidic resonator under (a) 10− 3 g/ml BSA (at 0, 1, 5, 15 mins, respectively) and (b) 10− 12 g/ml BSA (at 0 and 15 mins). (c) Real-time monitoring of WGM laser spectral shift of the LC-amplified optofluidic resonator under different BSA concentrations (10− 3, 10− 7, 10− 12 g/ml BSA, from top to bottom) within 15 mins. (Points in the same group are connected by B-spline curve)
