Evolving Advances in the Applications of Carbon Nanotubes (CNTs) for Management of Rheumatoid Arthritis (RA)

Rheumatoid arthritis (RA) is a chronic condition causing joint pain and inflammation that has now spurred the interest in nanotechnology-based drug delivery for more effective treatment, and in this regard, carbon nanotubes (CNTs) are being explored for their potential to deliver the drugs steadily to manage the RA. Many investigators have been investigating both single-walled carbon nanotubes (SWCNT) as well as multi-walled carbon nanotubes (MWCNT) for managing arthritis via targeted drug delivery. Moreover, functionalized CNTs show promise in delivering the drugs precisely and in a controlled manner, thereby minimizing toxicity. However, research on applications of CNTs as drug carriers for RA remains limited, thus necessitating further exploration to address the various challenges. In this present piece of writing, challenges in RA treatment and the advances in applications of CNTs for RA management are reported, consequently reflecting the CNTs as advanced drug delivery vehicles for arthritis treatment.

Fullerenes for Anticancer Drug Targeting: Teaching an Old Dog a New Trick

Fullerenes are the allotropic form of carbon consisting of a cage-like structure due to which they have attained special attention of the researchers since their discovery in 1985. The unique chemical and physical properties of fullerene have attracted researchers to develop a variety of its biomedical applications. The closed cage structure of fullerenes can be used for various drug delivery applications and can also act as a medium for controlled release formulations. The development of targeted anticancer drug and drug delivery systems is one of the most challenging fields, which is widely studied and researched. In this review, we aim to be comprehensive with a broad interest to the pharmaceutical and biotechnology community to provide the most recent advances on fullerenes as targeted anticancer drug delivery systems with therapeutic applications and challenges.
