A quantum dot (QD) is a semiconductor nanocrystal with a radius that is less than or equal to the exciton Bohr radius. As a new type of fluorescent marker, it shows great potential in biological and medical fields due to its unique tunable optical properties, such as a broad excitation spectrum, narrow emission spectra, tunable emission wavelength, and negligible photo-bleaching. Detection technology based upon this marker is simple, quick to use, sensitive, stable, and exhibits high throughput. The aim of this study was to examine the optical properties and surface modifications of QD in aquaculture pollution detection to assess potential applicability.
