Figure 3From: Enhanced sensitivity of surface plasmon resonance phase-interrogation biosensor by using oblique deposited silver nanorodsExperimental results of the relative phase difference between the p and the s waves. With different incident angles for various glucose solutions. The incident wavelength is fixed at 1,150 nm. The SPR sensing chips employed are oblique silver nanorod thin films of the thickness (a) 6, (b) 8, (c) 10, and (d) 12.5 nm, respectively.Back to article page
