摘要: To measure the concentration of C-reactive protein (CRP) in serum, a portable, scanning-fluorescence reader based on time-resolved fluoroimmunoassays was developed. The integrates with AD7707 converter, which performs at high accuracy. photosensitive diode acts as photoelectric conversion device, an optical module fibers, is able to concentrate excitation light from LED into line-shape beam, designed sendand receive signal. device subsequently addresses waveform data using gradient, smoothing, and binarization method. When measures CRP fluorescence test strip, results exhibited good linearity (0.99998) CVs (coefficient variation) were below 5%, indicate At same time system low cost small size.
