Special Issue Information

Dear Colleagues,

Chitosan is a polymer of natural origin with favourable properties, such as its ability to form chelates, non-toxicity, biocompatibility with the human body, and biodegradability, which can be used to form various structures (membranes, microgranules, sponges, etc.). Modifying chitosan into other forms such as hydrogels, nanoparticles, and nanofibers, or its crosslinking, grafting, combination with other materials, and ion templating, can allow the polymer to acquire even better properties than expected. Chitosan or chitosan-based composites can be applied in numerous important fields of our life, e.g., pharmacy, nutrition, environment, agriculture, medicine, and industry. If you work scientifically on chitosan and have any interesting results, please feel free to share them in this Special Issue entitled “Chitosan: Structural and Chemical Modification, Properties and Application, 2nd Edition” of the International Journal of Molecular Sciences. Research papers, communications, and reviews are all welcome.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The increasing presence of antibiotics in aquatic environments is a growing concern, causing ecological and public health risks. Even low concentrations of antibiotics may lead to the development of antibiotic-resistant bacteria. The interest in building new materials that can be used as templates for removing pollutants from the environment has been growing year upon year. We review the research involving adsorption processes that occur in chitosan-based materials that are employed to remove antibiotics from water. Since covering all the antibiotics that can be found in the environment would be an overwhelming task, we concentrated our efforts on describing the studies related to the removal of tetracycline, ciprofloxacin, cephalexin, and azithromycin, which are perhaps the most ubiquitous ones. We present the chemical modifications introduced into chitosan and chitosan-based materials commonly used as antibiotic adsorbents, as well as the influence of physical chemistry conditions on these processes. In addition, we also review in silico studies that have been carried out to obtain molecular-level insights into the interactions between chitosan-based adsorbents and the four mentioned antibiotics. Particular emphasis is placed on our recent computational work regarding the adsorption of tetracycline by various chitosan-based materials. Full article
