In this work, we proposed a single mode - tapered four core - single mode microfiber interference sensor for detecting C-reactive protein (CRP). The biosensor could detect CRP solution with a concentration of 1 pg/mL (diluted with phosphate buffered saline) with an average wavelength shift of 0.57 nm.
