Abstract: An optical probe for a bio-sensor selectively conjugated to a target analyte and configured to retro-reflect incident light thereto is disclosed. The optical probe for the bio-sensor includes: a transparent core particle; a total-reflection inducing layer covering a portion of a surface of the core particle, the inducing layer is made of a material having a refractive index lower than a refractive index of the core; a modifying layer formed on the total-reflection inducing layer; and an analyte-sensing substance bound to the modifying layer, the sensing substance is selectively conjugated to the target analyte. This optical probe may serve as an excellent optical probe for both a non-spectral light source and a spectral light source.
