ABSTRACT In recent years, despite significant advances in preconcentration and preparation techniques that have led to efficient recovery accurate measurement of target compounds. There is still a need develop adsorbents with unique features such as high pore volume surface area, reactivity, easy synthesis, low toxicity, compatibility the environment, which increase adsorption capacity extraction efficiency. Semiconductor nanocrystals called quantum dots (QDs) size less than 10 nm are three‐dimensional nanoparticles spherical, rod, or disc structure potential due their excellent properties environmental friendliness, hydrophilic hydrophobic interactions. One most basic issues development effective and, result, QDs, having an much higher conventional nanomaterials, suitable option for extracting compounds different environments. This work comprehensively reviews QD‐based methods modification strategies QDs based on functional groups, ligands, materials from 2013 2024. addition, applications composites organic inorganic analytes (residues drugs human blood plasma, toxins, pesticides, pollutants chemical industries, heavy metals, etc.) matrices investigated.
