carbon quantum dots as next-generation nanocarriers for targeted ocular drug delivery: innovations and therapeutic potential- a review

Carbon quantum dots (cqds) are gaining attention as useful nanomaterials because of their outstanding optical, physicochemical, and bio-compatible properties. their strong fluorescence, high water solubility, and easy ability to be modified make them good options for biomedical uses, especially in eye-related drug delivery and diagnosis. this review highlights how cqds can improve high-resolution imaging, targeted drug and gene delivery, and antioxidant therapy for eye diseases. their ability to enhance drug retention and reduce oxidative stress in conditions like diabetic retinopathy and cataracts shows their clinical importance. the review focuses on recent advancements in cqds for diagnosing and treating eye diseases, particularly drug delivery. further research and development are needed, but the progress may lead to new and effective ocular nano-medicines.
