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.
