The purpose of this thesis research project has been the development of a compact and versatile optoelectronic platform able to implement all the functionalities needed for a lab-on-chip operation. The project includes also the development of the electronics needed for the control of the system. In particular, the proposed platform includes three different modules designed for the fluid handling through the ElectroWetting On Dielectric (EWOD) technique, the thermal sample treatment and optical detection. These modules incorporate thin film microelectronic devices (such as photosensors and interferential filters for the optical detection, or heaters and temperature sensors for the sample treatments) on glass substrates connected to the electronic microcontrollers. Moreover, the use of handling techniques which avoid the use of pumps and syringes led to a portable, high-sensitive and low-power consumption lab-on-chip device. All of the modules have been designed, fabricated and tested separately. Finally, a device integrating all of the functionalities mentioned before has been designed for the development of a multifunctional platform able to perform a “true” lab-on-chip biomolecular system.
