  Hydrogels are three-dimensional networks of hydrophilic polymers capable of absorbing and retaining significant amounts of fluids, which are also widely applied in wound healing, cartilage tissue engineering, bone tissue engineering, release of proteins, growth factors, and antibiotics. In the past decades, a lot of research has been done to accelerate wound healing. Hydrogel-based scaffolds have been a recurring solution in both cases, although their mechanical stability remains a challenge, some of which have already reached the market. To overcome this limitation, the reinforcement of hydrogels with fibers has been investigated. The structural similarity of hydrogel fiber composites to natural tissues has been a driving force for the optimization and exploration of these systems in biomedicine. Indeed, the combination of hydrogel formation techniques and fiber spinning methods has been very important in the development of scaffold systems with improved mechanical strength and medicinal properties. Hydrogel has the ability to absorb secretions and maintain moisture balance in the wound. In turn, the fibers follow the structure of the extracellular matrix (ECM). The combination of these two structures (fiber and hydrogel ) in a scaffold is expected to facilitate healing by creating a suitable environment by identifying and connecting cells with the moist and breathing space required for healthy tissue formation. Modifying the surface of fibers by physical and chemical methods improves the performance of hydrogel composites containing Manuscript profile

  3 - Investigating the Particle Size of Chitosan-Based Drug Carriers for the Release of 5-Fluorouracil Antitumor Drug

  Chitosan has been widely used as a natural biopolymer. The modification of chitosan for various applications can be easily achieved due to the abundant active groups (NH2 and OH) in the main chain. Controlled drug release makes the drug release rate predictable and repeatable for prolonged release drugs. Drug delivery systems prepared from nanoparticles show several advantages, including improved efficiency and reduced toxicity. Using drug delivery systems based on nanoparticles loaded with anti-cancer agents is an effective method for targeting cancer cells. These systems, with the ability to penetrate better inside the cells, combine the drug in a targeted way in the cells. Also, due to the enhanced permeability and retention (EPR), the possibility of better accumulation of drugs in the tumor site is provided. In most researches, the suitable particle size for the targeted release of drug nanocarriers has been reported to be less than 300 or 200 nm. This amount is suitable for the application of drug release for diffusion among tissues and causes the effect of increasing permeability. In this study, for the first time, it examines and analyzes the particle size and zeta potential (surface charge) of chitosan-based nanocarriers through dynamic light scattering and electron microscope tests in improving the release of the antitumor drug, 5-fluorouracil.
