Surface Modification and Probe Immobilization Nimbolide site Verification Verification Modification X-ray photoelectron spectroscopy (XPS) surface analysis was performed working with a PHI Quantera II with an X-ray spot size of 200 nm. This experiment was performed to verify the surface modification step and good results with the probe immobilization. The silicon wafer immobilization. modification just before and just after surface modification, asas described in Section two.3 had been analyzedelement and soon after surface modification, described in Section two.three 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 Components). A scanning electron microscope (SEM) was used to confirm surface modification and modification probe immobilization around the device. The anti-mouse-gold antibody was applied 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 an anti-mouse antibody conjugated nano-gold particle having a with a size range 12 nm. 12 nano-gold particles will body conjugated nano-gold particle size range of 10 to of ten toThenm. The nano-gold parbe observed observed applying SEM. The anti-mouse-gold antibody was ready with 0.1 ticles will probably be making use of SEM. The anti-mouse-gold antibody was prepared with 0.1 phosphatebuffered saline (1:100) and (1:one hundred) and the pSiNWFET pSiNWFET ahead of and soon after pSiNphosphate-buffered saline loaded onto loaded onto thebefore and following pSiNWFET surface modification talked about in Section two.3. The anti-mouse-gold antibody was incubated for 2 h WFET surface modification pointed out in Section two.3. The anti-mouse-gold antibody was at space temperature. Subsequently, the anti-mouse-gold anti-mouse-gold antibody from incubated for 2 h at area temperature. Subsequently, the antibody from every pSiNWFET was pSiNWFET was washed with deionized water and dried pSiNWFET was coated eachwashed with deionized water and dried with nitrogen gas.

The pSiNWFET and nano-gold particles had been observed of IST, period selection of 10 to and nano-gold particles had been observed beneath the SEM setting beneath ten.0SEM setting of IST, ten.0 kv, 8.five.7 mm, 50.0 k magnification, and SE(U). the kv, eight.five.7 mm, 50.0 k magnification, and SE(U).two.5.
