Abstract:
An integrated circuit microchip sensor that detects a target biomolecule, the integrated circuit microchip sensor comprising:a probe that specifically binds to the target biomolecule;a solid support to which the probe is secured;at least one sensor connected to the probe, wherein the probe generates a detection signal, existing at a signal level related to a level of electromagnetic radiation detected by the sensor;a membrane positioned between the probe and the sensor, the membrane being capable of filtering the electromagnetic radiation;a lens secured to the solid support and positioned between the probe and the sensor; anddetection circuitry connected to at least one sensor for processing the detection signal, and for generating an output signal proportional to the detection signal, wherein the signal indicates the presence of the biomolecule in the sample.
