A recent update on development, synthesis methods, properties and application of natural products derived carbon dots

Abstract

Natural resources are practically infinitely abundant in nature, which stimulates scientists to create new materials with inventive uses and minimal environmental impact. Due to the various benefits of natural carbon dots (NCDs) from them has received a lot of attention recently. Natural products-derived carbon dots have recently emerged as a highly promising class of nanomaterials, showcasing exceptional properties and eco-friendly nature, which make them appealing for diverse applications in various fields such as biomedical, environmental sensing and monitoring, energy storage and conversion, optoelectronics and photonics, agriculture, quantum computing, nanomedicine and cancer therapy. Characterization techniques such as Photoinduced electron transfer, Aggregation-Induced-Emission (AIE), Absorbance, Fluorescence in UV–Vis and NIR Regions play crucial roles in understanding the structural and optical properties of Carbon dots (CDs). The exceptional photoluminescence properties exhibited by CDs derived from natural products have paved the way for applications in tissue engineering, cancer treatment, bioimaging, sensing, drug delivery, photocatalysis, and promising remarkable advancements in these fields. In this review, we summarized the various synthesis methods, physical and optical properties, applications, challenges, future prospects of natural products-derived carbon dots etc. In this expanding sector, the difficulties and prospects for NCD-based materials research will also be explored.

Copper-Doped Luteolin Carbon Dots with Antitumor Properties Based on the Induction of Immunogenic Cell Death

“…16−18 Their controllable functional properties make them ideal nanocapsules or nanocarriers. 19,20 While nanomaterials are typically used as drug carriers, the loading process is complex, with difficult control over loading rates. Therefore, regulating drug loading rates has become a significant challenge in the clinical application of nanomaterials.…”

“…Herbs play an increasingly important role in disease treatment. Carbon dots derived from herbal precursors often retain their original efficacy without requiring complex drug-loading processes that eliminate tedious preparation procedures. , The advantages exhibited by carbon dots derived from herbal medicines highlight the importance of herbs as precursors for physiologically functional carbon dots. Luteolin is a secondary metabolite of polyphenols found abundantly in vegetables, fruits, and herbs, which are widely employed for treating inflammatory diseases, hypertension, and cancer .…”
