Study on Trace Sample of Chronic Skin Ulcer with a Symmetrical Optical Waveguide

A prototype of symmetrical optical waveguide (SOW)-based surface plasmon resonance (SPR) sensing system is developed. Based on a polydopamine and matrix metalloproteinase-9 (MMP-9) antibody sensing protocol, trace samples of secretions from the chronic skin ulcer are detected with the SPR sensing sy
