“…In the¯lm deposition process, the substrates are heated to 350 C and applied a negative voltage of 150 V for the¯lm quality improvement. 15 Thē lm thickness and deposition rate are measured by an oscillator. Finally, the SPR chips are attached to SF4 prisms utilizing RI matching oil (Cargille) for construction of SPR modules.…”

“…The thickness di®erence between the polydopamine¯lms may be caused by the di®erent surface characteristics caused by the¯lm uniformity and di®erent°ow conditions in di®erent channels. The evanescent wave penetration depth of SPR sensor is usually at the level of 400 nm, 15 so the polydopamine¯lm with the thickness of several nanometers cannot a®ect the SPR sensor characteristics. Using the electromagnetic theory described in Ref.…”

“…The SPR chip without polydopamine¯lm is observed using accelerate voltage of 15000 V for comparison. The gold¯lm coating using magnetron sputtering is based on island growth dynamic process, 15 so the gold atoms located in the junction of di®erent islands are not tightly adhesive to the Cr layer and they could be blown away by high-energy electrons, which lead to the black lines in the micrographs shown in Figs. 5(b) and 5(c).…”

Surface functionalization of sensor chip for probe immobilization is crucial for the biosensing applications of surface plasmon resonance (SPR) sensors. In this paper, we report a method circulating the dopamine aqueous solution to coat polydopamine¯lm on sensing surface for surface functionalization of SPR chip. The polydopamine¯lm with available thickness can be easily prepared by controlling the circulation time and the biorecognition elements can be immobilized on the polydopamine¯lm for speci¯c molecular interaction analysis. These operations are all performed under°ow condition in the°uidic system, and have the advantages of easy implementation, less time consuming, and low cost, because the reagents and devices used in the operations are routinely applied in most laboratories. In this study, the speci¯c absorption between the protein A probe immobilized on the sensing surface and human immunoglobulin G in the bu®er is monitored based on this surface functionalization strategy to demonstrated its feasibility for SPR biosensing applications.
