Special Issue Information

Dear Colleagues,

In recent decades, chitosan biomaterial, mainly in its nanostructure form, has gained extraordinary relevance in the biomedical field due to its unique biological properties. It is nontoxic, biodegradable, biocompatible, mucoadhesive and promotes mucosal drug absorption. In addition, it has antibacterial, antimicrobial, anti-inflammatory, antitumor, immunostimulatory and wound healing properties. For all these reasons, chitosan and its derivatives are having an enormous impact on the fields of drug delivery, gene therapy, vaccination, tissue engineering, regenerative medicine and wound dressing, among others. In their application, the use of chitosan-based starting materials that are well characterized is an urgent requirement, and the properties of chitosan derivatives are being continuously improved to ensure they are suitable for application.

This Special Issue focuses on the latest research advances on systems based on chitosan and its derivatives in biomedicine, including (but not limited to): (a) delivery of proteins, antibiotics, antigens and nucleic acids; (b) diagnosis and treatment of cancer (theranostics); and (c) applications in tissue engineering. The aim is to provide an updated status and perspectives on future research in the aforementioned topics and to emphasize the challenges for their translation to the clinic.

Original research articles and review manuscripts on the aforementioned topics are welcome.

Most infectious diseases of the gastrointestinal tract can easily be treated by exploiting the already available antibiotics with the change in administration approach and delivery system. Ciprofloxacin (CIP) is used as a drug of choice for many bacterial infections; however, long-term therapy and off-site drug accumulation lead to an increased risk of tendinitis and peripheral neuropathy. To overcome this issue, nanotechnology is being exploited to encapsulate antibiotics within polymeric structures, which not only facilitates dose maintenance at the infection site but also limits off-site side effects. Here, sodium alginate (SA) and thiol-anchored chitosan (TC) were used to encapsulate CIP via a calcium chloride (CaCl2) cross-linker. For this purpose, the B-390 encapsulator was employed in the preparation of nanobeads using a simple technique. The hydrogel-like sample was then freeze-dried, using trehalose or mannitol as a lyoprotectant, to obtain a fine dry powder. Design of Experiment (DoE) was utilized to optimize the nanobead production, in which the influence of different independent variables was studied for their outcome on the polydispersity index (PDI), particle size, zeta potential, and percentage encapsulation efficiency (% EE). In vitro dissolution studies were performed in simulated saliva fluid, simulated gastric fluid, and simulated intestinal fluid. Antibacterial and anti-inflammatory studies were also performed along with cytotoxicity profiling. By and large, the study presented positive outcomes, proving the advantage of using nanotechnology in fabricating new delivery approaches using already available antibiotics. Full article
