Rheumatoid arthritis is a chronic autoimmune disease characterised by joint synovial inflammation, along with cartilage and bone tissue destruction. Dendrimers can offer new opportunities as drug delivery systems of molecules of interest. Herein we aimed to develop poly(amidoamine) dendrimers (PAMAM), functionalised with chondroitin sulphate (CS), lined with anti-TNF α antibodies (Abs) to provide anti-inflammatory properties. Physicochemical characterisation demonstrated that anti-TNFα Abs-CS/PAMAM dendrimer NPs were successfully produced. The\ in vitro\ studies revealed that CS/PAMAM dendrimer NPs did not affect the ATDC5 and THP-1 cell lines{\textquoteright} metabolic activity and proliferation, presenting good cytocompatibility and hemocompatibility. Moreover, anti-TNFα Abs-CS/PAMAM dendrimer NPs showed suitable TNF α capture capacity, making them appealing for new immunotherapies in RA patients.
