Special Issue Information
Dear Colleagues,
Polysaccharides are widely available polymers from agricultural and marine sources. Some of them can be produced by sustainable biotechnologies involving selected microorganisms. Unexploited waste material represented from fishery by-products and plant biomass are estimated to amount to around 300 million tons per year, and only 20% is used to produce almost exclusively energy. This is a very important source of polysaccharides, and its better exploitation could contribute to limit the impact of both fossil resources depletion and environmental pollution. The biodegradability and compatibility of polysaccharides with body and skin give them an intrinsic safety, and thus the possibility to be used in several fields: from food packaging to cosmetics, from personal care/sanitary products to biomedical ones. Nano-structured versions of fibrous polysaccharides such as cellulose and chitin are currently being produced by interesting new methodologies, making it possible to exploit interesting high performances correlated to their nano-dimensions, also considering suitable modification technologies or the combination of these nano-fibers with other nanostructured materials such as nano-lignin, inorganic nanomaterials, or specific functional molecules. The preparation and testing of such nano-structured materials is a current frontier in research. Polysaccharides are also used in biobased materials and nanocomposites with enhanced performances thanks to the improved interfacial areas and functional properties. In this case, the capacity of testing the material properties up to the nano-scale is fundamental in order to clarify the correlations between their chemical structures, morphologies, and final properties. Their processability thanks to new or hyphenated technologies such as extrusion, molding, electrospinning, and 3D printing—including coating technologies exploiting nano-technology—is also fundamental for enhancing their high performances.
This Special Issue aims to gather research and review papers to increase the knowledge and use of polysaccharides and their derived compounds in nano-structured materials, finding new ways to produce innovative, sustainable, and smart products for use in several applications.

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. Nanomaterials is an international peer-reviewed open access semimonthly 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 2900 CHF (Swiss Francs). 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.
