Abstract
An optical biosensor includes a sensing block that receives a first optical signal and outputs a second optical signal through at least one channel of a plurality of channels that correspond to a sensed concentration of a biomaterial; and a detecting block that detects the second optical signal, converts the second optical signal into an electrical signal, and outputs the electrical signal.
Claims20
An optical biosensor comprising:
- a sensing block that receives a first optical signal and outputs through at least one channel of a plurality of channels a second optical signal that corresponds to a sensed concentration of a biomaterial;
- and
- a detecting block that detects the second optical signal, converts the second optical signal into an electrical signal using a plurality of photodetectors, and outputs the electrical signal.
A bio-sensing system comprising:
- a fluidic channel through which a biomaterial flows;
- and
- a biosensor chip having an opening that contacts the fluidic channel and that senses a concentration of the biomaterial flowing through the fluidic channel based on an optical characteristic and outputs the concentration of the biomaterial as an electrical signal,
- wherein the biosensor chip has integrated onto one substrate a sensing block that senses a concentration of a biomaterial to output the concentration of the biomaterial as an optical signal, and a detecting block that converts the optical signal received from the sensing block into an electrical signal.
1 more element
An optical biosensor comprising:
- a sensing block comprising one or more optical resonators, each of the one or more optical resonators adapted to removing a different resonant optical wavelength from a first optical signal comprising a plurality of wavelengths to generate a sensing optical signal, wherein said optical resonators are adapted for receiving and coupling to a biomaterial that changes the resonant optical wavelength of the resonator;
- and
- a plurality of output channels, each output channel corresponding to a different resonant optical wavelength that corresponds to a sensed concentration of a biomaterial.
