A BIO-THERMOCHEMICAL MICROBOLOMETER WITH IMMOBILIZED INTACT LIPOSOME ON SENSOR SOLID SURFACE

摘要

We have developed a scheme of bio-thermochemical microbolometer with immobilized intact liposome on sensor solid surface. A liposome of 1,2-dipalmitoyl-sn-glycero-3-phosphocholline (DPPC) was confirmed to be deposited intact by XRD and AFM analysis on a Pt film that is used as resistive bolometer material. As a primal stage, we believe that thermochemical reactions of DPPC on phase transition among gel, ripple and fluid phases have been successfully detected, by using a fabricated surface micromachined thermal cavity beneath the Pt resistor film.
