This paper describes our point-of-care system development based on localized surface plasmon resonance (LSPR). Although LSPR has been a hot research area for a few decades, there are several bottlenecks which hampered its application for point-of-care (POC) medical diagnostics. The first is the detection sensitivity shortage when the direct LSPR wavelength shift is used for sensing, the second is...
Nanosphere lithography is an inexpensive method used to fabricate gold nanostructures on a substrate. Using dispersed-nanosphere lithography, in which the nanospheres are dispersed on a substrate, 2D or 3D nanostructures can be fabricated by obliquely depositing a gold film on the nanospheres and etching the gold film afterward. These nanostructures are tunable and acute, and are thus good emitting...
