Summary: A Fe3+ optical sensor was developed by linking CdTe quantum dots and a Rhodamine B derivative using gamma-cyclodextrin as a bridge. The nanoprobe displayed a response to Fe3+ through a fluorescence resonance energy transfer process. The probe showed satisfactory linearity in the fluorescent quenching between 10 and 60 μM Fe3+ concentration, with a limit of detection of 2.51 μM. The probe was successfully used for the determination of Fe3+ in human serum with high sensitivity and exceptional selectivity.

Summary: Semiconductor nanomaterials, known as quantum dots (QDs), have attracted significant interest for their excellent optical properties and potential biomedical applications. However, the presence of toxic heavy metals in conventional QDs poses a major challenge. Ternary I-III-VI QDs have emerged as viable alternatives with tunable optical properties that emit in the near-infrared region. This review discusses the recent progress in using ternary QDs in applications such as Forster resonance energy transfer (FRET), nanomedicine, optical imaging, biosensing, and multimodal imaging. It also examines the pharmacokinetics, biodistribution, and toxicity concerns of these QDs, as well as the current status, challenges, and future directions in their application.
