Abstract

An optical bio-sensing device includes a transparent substrate covering a top of a space accommodating therein a sample containing a target bio-material; a signal converter fixed to the transparent substrate, and including the upconversion nanoparticles for receiving incident light and emitting converted light of a wavelength shorter than a wavelength of the incident light; a signal reflector including retroreflection particles bindable to the signal converter via the target bio-material, wherein the retroreflection particles retroreflect the converted light; a light source for irradiating the incident light to the signal converter; and a light receiver for receiving light retroreflected from the signal reflector.
