主 题:microfluidic chip light-emitting diode optical fiber detector
摘 要:The diameter of the excitation beam was decreased greatly by integrating the fiber on the microfluidic chip as light propagation *** coupling efficiency of the fiber was improved with optical fiber collimation device coupling beam. The chip was placed in the darkroom to avoid the interference of the external *** cost of the instrument was decreased with a high brightness blue LED as excitation source;the performance of the system was valuated by the determination of FITC fluorescein with a minimum detectable concentration of 2.2×10^(-8) mol/L,the Signal-to-Noise Ratio (SNR) S/N=*** correlation coefficient of the detection system within the range of 1.8×10^(-7) mol/L~4×10^(-5)mol/L was 0.9972.
