Abstract
A sensor, such as a lateral flow sensor, which includes a chemical layer and a detector on a flexible substrate. An optical signal is produced in response to an analyte placed on the chemical layer. The detector detects the signal, to thereby detect the presence, absence or concentration of the analyte. The detector is on the substrate. The chemical layer and the substrate are laminated together, to thereby form an integrated sensor. The sensor can include a light source. The light source can be on the substrate, or on an opposite side of the chemical layer than the detector.
Claims21
An apparatus comprising:
- a chemical layer via which an optical signal is produced in response to an analyte being placed on the chemical layer;
- a detector which detects the optical signal to thereby detect presence, absence or concentration of the analyte;
- and
- a substrate, wherein the detector is on the substrate, and the chemical layer and the substrate are laminated together.
An apparatus comprising:
- a chemical layer via which an optical signal is produced in response to an analyte being placed on the chemical layer;
- a detector, being an organic photodiode or amorphous silicon, which detects the signal to thereby detect the presence, absence or concentration of the analyte;
- an organic light emitting diode (OLED) which emits a light that causes the optical signal to be produced or detected in response to the analyte being placed on the chemical layer;
- and
- a substrate, wherein the detector and the OLED are manufactured directly on the substrate, and the chemical layer and the substrate are laminated together.
An apparatus comprising:
- a chemical layer via which an optical signal is produced in response to an analyte being placed on the chemical layer;
- and
- a detector which detects the signal, to thereby detect presence, absence or concentration of the analyte, wherein the chemical layer and the detector are integrated together by lamination.
