Integration of fluorescence sensors using organic optoelectronic components for microfluidic platform

Since the emergence of microfluidic platforms, optical sensor integration has been a major challenge. With the advances in miniaturization of these platforms, there is a need of solutions to integrate various optical components in order to build sensors, which will offer different detection characteristics such as several emission and sensing wavelengths. In this perspective, organic optoelectronic devices could be a solution. The integration of a fluorescent sensor into a microfluidic platform and the different characteristics (optical, electrical, geometric), advantages and disadvantages that offer organic light-emitting diodes (OLED) and organic photodetectors (OPD) for fluorescent sensors are discussed. Finally, an example of integration of organic optoelectronic components into a microfluidic chip for phytoplankton fluorescence detection will be described. (C) 2015 Elsevier B.V. All rights reserved.
