Laser Printing of Organic Electronics and Sensors

摘要

This work presents the use of the Laser-Induced Forward Transfer (LIFT) process as an advanced tool for organic electronics and biosensor fabrication. LIFT is an alternative micro-patterning technology that employs pulsed laser irradiation for the selective deposition of a liquid or solid target material onto a receiving substrate. LIFT) is a non-contact direct printing method that can deposit patterns of functional materials, in liquid or in solid phase, including organic, carbon-based nanomaterials, biological compounds, metal nanoparticles, and dielectrics on different substrates including flexible materials. More specifically, the LIFT process is used for direct printing of Ag-based nanoparticles, organic semiconducting materials for organic transistors and biomaterials (enzymes and photosynthetic proteins) for environmental biosensor fabrication. The use of LIFT has shown the possibility of direct immobilization of biomaterials onto the surface of the sensors without the use of chemical linkers.
