We reported the fluorescence sensor of carbon dots (CDs) synthesized for the highly sensitive and selective detection of bilirubin in human urine. High-resolution transmission electron microscopy (HRTEM) images showed that the CDs have a spherical shape with a mean particle size of 2.6 nm.

A fluorescent probe based on silicon quantum dots (SiQDs) was developed for the selective and sensitive detection of oxytetracycline (OTC) via the inner filter effect (IFE). The water-soluble fluorescent SiQD was synthesized based on the reaction of 3-Aminopropyltriethoxysilane (APTES) and sodium citrate as precursors by the one-pot hydrothermal process. The strong fluorescence emission of quantum dots (QDs) was obtained at 440 nm when excited at 350 nm and OTC had a broad absorption band between 200 and 400 nm.
