Quantum Dots (QDs) are semiconductor nanocrystals with distinct photophysical properties finding applications in biology, biosensing, and optoelectronics. Polymeric coatings of QDs are used primarily to provide long-term colloidal stability to QDs dispersed in solutions and also as a source of additional functional groups used in further chemical derivatization of the nanoparticles. We review the coating methods, including multidentate and amphiphilic polymeric coatings, and grafting-to and grafting-from approaches. We highlight the most commonly used polymers and discuss how their chemical structure influences the coating properties.
量子点（QDs）是具有独特光物理性质的半导体纳米晶体，在生物学、生物传感和光电子学中有广泛的应用。QDs 的聚合物涂层主要用于为分散在溶液中的 QDs 提供长期胶体稳定性，并且还作为用于纳米粒子进一步化学衍生化的附加官能团的来源。我们综述了涂层方法，包括多齿和两亲性聚合物涂层以及接枝到和从接枝的方法。我们强调了最常用的聚合物，并讨论了它们的化学结构如何影响涂层性能。
