Fiber-optic particle plasmon resonance sensor for detection of interleukin-1β in synovial fluids.


A facile and label-free biosensing method has been developed for determining an osteoarthritis concerned cytokine, interleukin-1β (IL-1β), in synovial fluids. The biosensing technique, fiber-optic particle plasmon resonance (FOPPR), is based on gold nanoparticles-modified optical fiber where the gold nanoparticle surface has been modified by a mixed self… (More)
