Abstract
The present disclosure provides a complex having satisfactory dispersibility and stable luminescence characteristics. A complex of the present disclosure includes: a first substance having a property of specifically binding to a target substance; a quantum dot that contains silicon as a main component and that is negatively charged on a surface; and a linker substance that contains a compound represented by general formula (1) below and that covers the surface of the quantum dot, where the first substance has been immobilized on the surface of the quantum dot through the linker substance: X—L—Si—(R1)(R2)(OR3) (1) where X is a basic functional group; R1, R2, and R3 are each independently an alkyl group; and L is an alkylene group.
