Application of carbon dots in sample pretreatment and chromatographic separation

Carbon dots (CDs) have the advantages of good biocompatibility, low toxicity and high stability, and have been widely used in bioimaging, sensing, photocatalysis, etc. In recent years, sample pretreatment and chromatographic separation studies using CDs as adsorbents and separation materials have also attracted much interest. In this review, the applications of CDs in sample pretreatment and chromatographic separation are summarized, and further development prospects are prospected.
