Special Issue Information

Dear Colleagues,

Cellulose is a common and important organic compound on Earth, found in the cell wall of green plants and many forms of algae, fungi and molds. As the most abundant polymer, it is one of the oldest raw materials that have been used by humans since the dawn of civilization. Due to its unique structure and excellent properties, such as biocompatibility, biodegradability, chemical stability and derivatization, coupled with its low cost, abundance, availability and renewability, cellulose has various large- and small-scale applications, e.g., building and construction materials, paper, paperboard and packaging, cotton and textiles, food ingredients and feed, heat and luminous sources and so on. However, there are still great challenges that facilitate this natural polymer to be further used, especially the development of a new and green platform for cellulose shaping through chemical and/or physical modification. Among these, cellulose-based gels offer new opportunities and open new frontiers over a broad range of applications.

This Special Issue is intended to be a thorough collection of articles dealing with all the aspects of cellulose-base gels, from their synthesis and characterization to their use and development during the last few years.

The publication of original research articles, rapid communications or reviews in this Special Issue will make an important contribution to the development of cellulose-based gel science.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Gels is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs).

Metallogels represent a class of composite materials in which a metal can be a part of the gel network as a coordinated ion, act as a cross-linker, or be incorporated as metal nanoparticles in the gel matrix. Cellulose is a natural polymer that has a set of beneficial ecological, economic, and other properties that make it sustainable: wide availability, renewability of raw materials, low-cost, biocompatibility, and biodegradability. That is why metallogels based on cellulose hydrogels and additionally enriched with new properties delivered by metals offer exciting opportunities for advanced biomaterials. Cellulosic metallogels can be either transparent or opaque, which is determined by the nature of the raw materials for the hydrogel and the metal content in the metallogel. They also exhibit a variety of colors depending on the type of metal or its compounds. Due to the introduction of metals, the mechanical strength, thermal stability, and swelling ability of cellulosic materials are improved; however, in certain conditions, metal nanoparticles can deteriorate these characteristics. The embedding of metal into the hydrogel generally does not alter the supramolecular structure of the cellulose matrix, but the crystallinity index changes after decoration with metal particles. Metallogels containing silver (0), gold (0), and Zn(II) reveal antimicrobial and antiviral properties; in some cases, promotion of cell activity and proliferation are reported. The pore system of cellulose-based metallogels allows for a prolonged biocidal effect. Thus, the incorporation of metals into cellulose-based gels introduces unique properties and functionalities of this material. Full article
