INTEGRATION OF OLED LIGHT SOURCE AND OPTICAL FIBERS ON A PDMS BASED MICROFLUIDIC DEVICE FOR ON-CHIP FLUORESCENCE DETECTION

摘要

A detection device is proposed with an integrated light source based on Organic Material. The microfluidic channels are fabricated using PDMS material, with also an inlet channel where an optical fiber is inserted and put close to the microfluidic channel. This fiber is then plugged to a PMT to analyze the fluorescent emission. Measurements were carried out with several concentrations of Rhodamine B, from 1 to 100 μM. The output voltage shows a linear response versus the dye concentration, but the results also exhibit problems that should be solved in order to improve the chip sensitivity.
