Carbon nanodots (CNDs) have garnered significant attention as viable drug delivery vehicles in recent years, especially in the field of phytomedicine. Although there is much promise for therapeutic applications with phytomedicine, its effectiveness is frequently restricted by its low solubility, stability, and bioavailability. This paper offers a thorough synopsis of the developing field of phytomedicine drug delivery based on CND. It explores CND synthesis processes, surface functionalization strategies, and structural and optical characteristics. Additionally, the advantages and difficulties of phytomedicine are examined, with a focus on the contribution of drug delivery methods to the increased effectiveness of phytomedicine. The applications of CNDs in drug delivery are also included in the review, along with the mechanisms that underlie their improved drug delivery capabilities. Additionally, it looks at controlled release methods, stability augmentation, and phytomedicine loading tactics onto CNDs. The potential of polymeric carbon nanodots in drug delivery is also covered, along with difficulties and prospective directions going forward, such as resolving toxicity and biocompatibility issues. In summary, the present review highlights the encouraging contribution of CNDs to the field of drug delivery, specifically in enhancing the potential of phytomedicine for therapeutic purposes.

The dynamic interaction between carbon nanodots (CNDs) and cannabidiol (CBD) has captured significant attention as an innovative avenue for redefining drug delivery and amplifying therapeutic effectiveness. This in-depth review delves into the intricate synergy between these two elements, unveiling their profound potential in medicine. Commencing with an examination of the unique characteristics of CNDs and the techniques governing their synthesis, we discuss their versatility as drug carriers, highlighting their invaluable role in advancing CBD delivery. Cannabidiol, a non-psychoactive compound sourced from cannabis, has emerged as a focal point for its diverse therapeutic attributes. Nevertheless, the limitations posed by its restricted bioavailability and susceptibility to degradation pose substantial hindrances to realizing its full potential. Here, we elucidate how the amalgamation of CBD with CNDs transcends these challenges. We delve into the mechanisms that underlie this synergy, such as the augmentation of solubility and the safeguarding of CBD against premature breakdown, providing an intricate analysis. We will also journey you through a comprehensive exploration of diverse CBD loading techniques onto CNDs, dissecting the realms of physical encapsulation, covalent bonding, and adsorption processes. In summation, the combination of CNDs and CBD presents an extraordinary opportunity to elevate therapeutic outcomes. This synergetic paradigm masterfully tackles pivotal challenges in drug delivery, thereby paving the path for pioneering medical solutions.
