Surface Modification and Probe Immobilization Verification Verification Modification X-ray photoelectron spectroscopy (XPS) surface PF-06873600 web evaluation was performed employing a PHI Quantera II with an X-ray spot size of 200 nm. This experiment was performed to confirm the surface modification step and achievement from the probe immobilization. The silicon wafer immobilization. modification prior to and just after surface modification, asas described in Section 2.3 had been analyzedelement and soon after surface modification, described in Section two.3 have been analyzed its its eleof carbon (C), nitrogen (N) and oxygen (O) (Figure S1 in S1 in Supplementary Supplies). ment of carbon (C), nitrogen (N) and oxygen (O) (Figure Supplementary Materials). A scanning electron microscope (SEM) was applied to confirm surface modification and modification probe immobilization on the device. The anti-mouse-gold antibody was made use of to interact with all the immobilized HBsAb. The anti-mouse-gold antibody is an anti-mouse IgG IgG antithe immobilized HBsAb. The anti-mouse-gold antibody is definitely an anti-mouse antibody conjugated nano-gold particle using a having a size variety 12 nm. 12 nano-gold particles will body conjugated nano-gold particle size range of ten to of 10 toThenm. The nano-gold parbe observed observed utilizing SEM. The anti-mouse-gold antibody was ready with 0.1 ticles will probably be employing SEM. The anti-mouse-gold antibody was prepared with 0.1 phosphatebuffered saline (1:100) and (1:one hundred) along with the pSiNWFET pSiNWFET just before and right after pSiNphosphate-buffered saline loaded onto loaded onto thebefore and immediately after pSiNWFET surface modification described in Section 2.three. The anti-mouse-gold antibody was incubated for 2 h WFET surface modification mentioned in Section 2.3. The anti-mouse-gold antibody was at space temperature. Subsequently, the anti-mouse-gold anti-mouse-gold antibody from incubated for two h at room temperature. Subsequently, the antibody from each pSiNWFET was pSiNWFET was washed with deionized water and dried pSiNWFET was coated eachwashed with deionized water and dried with nitrogen gas.
