FUNCTIONALIZATION OF MICROCANTILEVER SENSORS USING INKJET DROP-ON-DEMAND

摘要：

Chemical and biochemical sensors based on microcantilever arrays have emerged as new platforms for sensitive analyte detec-tion.A critical step in the manufacture of microcantilever sen-sorsis the functionalization process, where a chemically selec-tivelayer is deposited onto the surface of the cantilever. Inkjet drop-on-demand has been recognized as a befitting technology for depositing these layers because of the ability to repeatedly deposit precise amounts of fluid. This paper presents experimen-talresults of applying inkjet printing to functionalize microcan-tileversensors. Methods for tuning inkjet drive pulse are pre-sentedalong with characterization of drop displacement. Strate-giesfor printing the functional layer are presented and system capabilities are demonstrated by depositing black ink onto can-tilevers.
