“…The former method involves strategies based on the size reduction of bulk materials under the influence of a beam [ 12 ] ( Figure 2 ). Techniques such as ion beam implantation, electron beam lithography, molecular beam epitaxy, and x-ray lithography are included in this first category [ 13 ] and allow us to synthesize nanoparticles of InGaAs/GaAs [ 14 ], InGaN/GaN [ 15 ], among others. In a typical lithographic process, the QDs are deposited onto a silicon substrate coated with gold, to further draw a pattern by lithography over the QDs layer.…”

Ternary quantum dots (QDs) are novel nanomaterials that can be used in chemical analysis due their unique physicochemical and spectroscopic properties. These properties are size-dependent and can be adjusted in the synthetic protocol modifying the reaction medium, time, source of heat, and the ligand used for stabilization. In the last decade, several spectroscopic methods have been developed for the analysis of organic and inorganic analytes in biological, drug, environmental, and food samples, in which different sensing schemes have been applied using ternary quantum dots. This review addresses the different synthetic approaches of ternary quantum dots, the sensing mechanisms involved in the analyte detection, and the predominant areas in which these nanomaterials are used.
