The paper presents the first part of the work focused on preparation of biodegradable chitosan microcapsules with tailored properties for potential applications in medical field as drug temporary carriers. In this paper, we aimed to prepare chitosan and chondroitin sulphate microcapsules using TPP as the second cross-linker and investigate the formation of the capsule membrane and its permeability in dependence on conditions of polyionic complexation. As a model, TPP was used to assess an influence of concentration and reaction time on the microcapsule formation. The method of inverse SEC was used for pores size and permeability limit of capsules assessment. For chitosan/CHS/TPP capsules, the distribution of pores size in the membrane is rather broad, which can be suitable for applications in tissue engineering and drug delivery systems.

Carbon nanotube-natural biopolymer nanovectors have important potential applications in delivery system for drugs and biomolecules. In this work, the use of multi-walled carbon nanotubes (MWCNT) as nanoreservoirs for drug loading and controlled release is demonstrated. We synthesized different carbon nanotube-based drug delivery systems including acid and amide-functionalized MWCNT; chitosan (CS) covalently grafted to functionalized MWCNT and MWCNT-CS nanoparticles (NPs) using an ionotropic gelation method as a sustained-release systems for delivery of Tenofovir (hydrophilic anti-retroviral drug). The prepared NPs as different drug delivery systems were characterized by Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA) and scanning electron microscopy (SEM). As it is shown, in vitro drug release studies indicated that the cumulative release rate of Tenofovir from MWCNT–CS NPs shows the best result and it reaches the maximum value (90%) after about 120 h. Moreover, comparing to ungrafted CNTs, MWCNT–CS shows high dispersability and long-term stability in aqueous medium which approves the effective solubilization of MWCNT followed by grafting with CS.

Graphene, a two-dimensional nanomaterial with unique biomedical properties, has attracted great attention due to its potential applications in graphene-based drug delivery systems (DDS). In this work graphene sheets with various sizes and graphene oxide functionalized with polyethylene glycol (GO-PEG) are utilized as nanocarriers to load anticancer drug molecules including CE6, DOX, MTX, and SN38. We carried out molecular dynamics calculations to explore the energetic stabilities and diffusion behaviors of the complex systems with focuses on the effects of the sizes and functionalization of graphene sheets as well as the number and types of drug molecules. Our study shows that the binding of graphene-drug complex is favorable when the drug molecules and finite graphene sheets become comparable in sizes. The boundaries of finite sized graphene sheets restrict the movement of drug molecules. The double-side loading often slows down the diffusion of drug molecules compared with the single-side loading. The drug molecules bind more strongly with GO-PEG than with pristine graphene sheets, demonstrating the advantages of functionalization in improving the stability and biocompatibility of graphene-based DDS.

Recent advances in science and technology radically changed the way we detect, treat and prevent different diseases in all aspects of human life. Rheumatoid arthritis (RA) is a chronic, systemic, progressive, autoimmune disease in which the body’s immune system whose major role is to protect the health by attacking foreign bacteria and viruses are mistakenly, attacking the joints resulting in thickened synovium, pannus formation, & destruction of bone, cartilage. Still now researchers are unable to know the exact cause of this disease. However, it is believed that genes and environmental factors play a role in development of RA. In this review, we discuss the Pathophysiology, predictors, & factors involved in pathogenesis of RA. We also discuss the Conventional therapeutic agents for Rheumatoid Arthritis. More importantly, we extensively discuss the emerging novel drug delivery systems (NDDS) like nanoparticles, dendrimers, micelles, microspheres, liposomes, and so on as these are the promising tools having successful applications in overcoming the limitations associated with conventional drug delivery systems. Although several NDDS have been used for various purposes, liposomes have been focused on due to its potential applications in RA diagnosis and therapy. In addition, we discuss the therapeutic effectiveness and challenges for RA by using these novel drug delivery systems. Finally, we conclude by discussing the future perspectives.
