Bioassay system including optical detection apparatuses, and method for detecting biomolecules
First Claim
1. An apparatus for identifying a single biomolecule, comprising:
- a substrate having a light detector, the substrate being configured to detect light emitted from the biomolecule;
a blind sheet over the substrate, the blind sheet including a pinhole having a diameter;
a filter layer provided between the blind sheet and the substrate and provided under the pinhole, the filter layer being non-planar and configured to filter the light emitted from the biomolecule; and
a linker site provided proximate to the pinhole, the linker site being treated to position the biomolecule proximate to the pinhole.

Abstract
A bioassay system is disclosed. The bioassay system may include a plurality of optical detection apparatuses, each of which includes a substrate having a light detector, and a linker site formed over the light detector, the linker site being treated to affix the biomolecule to the linker site. The linker site is proximate to the light detector and is spaced apart from the light detector by a distance of less than or equal to 100 micrometers. The light detector collects light emitted from the biomolecule within a solid angle of greater than or equal to 0.8 SI steridian. The optical detection apparatus may further include an excitation light source formed over the substrate so as to provide a light source for exciting a fluorophore attached to the biomolecule.
