Optical fiber biosensor and preparation method and application thereof

The invention discloses an optical fiber biosensor, which is prepared by coating the surface of an amino-functionalized waist-tapered optical fiber sensor with a graphene oxide layer and adsorbing an aptamer NE-AP or an aptamer LF-AP on the surface of the graphene oxide layer. The aptamer NE-AP can be specifically combined with the elastinase ELANE; the aptamer LF-AP can be specifically combined with the lactoferrin LF. After the optical fiber biosensor captures ELANE and LF proteins, the roughness and thickness of the surface of the optical fiber at the waist-cone-shaped part are changed, when light penetrates through the waist-cone-shaped part covered by biomolecules, the effective refractive index of the surface of the optical fiber biosensor is changed due to the fact that the diameter is gradually reduced and an evanescent field outside a core is enhanced, and the optical fiber biosensor can be used for detecting the optical fiber in the waist-cone-shaped part. Therefore, red shift occurs according to a transmitted spectrum induced after aptamer-protein combination is tracked, and high-sensitivity and low-detection-limit detection on the activity of the neutrophil is realized. The method has the characteristics of high sensitivity and low detection limit.
