Photopatternable polymeric membranes for optical oxygen sensors


Raghu Ambekar


"Optical oxygen sensors are the most popular type of oxygen sensors because of their advantageous features like fast response, no electrical interference, high sensitivity and no oxygen consumption compared to its electrochemical counterpart. Most of the optical oxygen sensors are based on the principle that oxygen quenches the luminescence emitted from the luminescent dyes, such as porphyrin and ruthenium complex, which are immobilized in an oxygen permeable membrane. In bio-MEMS applications, there is a large need of microscopically patterned optical membranes to measure chemical parameters in a small local area. Most of the oxygen sensitive membranes are, however, non-patternable and very little progress has been made towards producing patternable optical membranes. In this work, a new class of optical oxygen sensors that can be photopatternable by traditional UV lithography is presented"--Abstract, page iv.
