Special Issue Information
Dear Colleagues,
The increasing cost of petroleum and the prospect of a shortage of its natural deposits imply the necessity of searching for alternative sources of energy and industrial raw materials. Polysaccharides are a commonly available, cheap, sustainable and renewable group of organic compounds. They are considered as attractive raw materials, providing access to several novel biodegradable materials that are attractive for chemical, food and pharmaceutical industries. There is more interest than ever when it comes to natural polysaccharides and spreading the fields of their potential applications.
Due to their chemical structure, polysaccharides can be readily modified via physical, physicochemical, chemical and enzymatic methods. Numerous studies have confirmed the bioactivity of polysaccharides, providing their applications in clinical practice, nutrition and dietetics. Depending on their origin, polysaccharides exhibit antioxidative, immunomodulating, anti-inflammatory, antiviral (among others, HIV), antimutagenic, cancerostatic and anticlotting properties.
Polysaccharides offer a wide range of key parameters essential for their practical use, for instance, low, medium and high molecular weights, variable polydispersity, forming linear and branched macrostructures, monofunctionality (compounds bearing solely hydroxyl groups) and polyfunctionality (compounds with hydroxyl, carboxylic and/or amino groups), high degrees of chirality, either low or high aqueous solubility, and low, if any, toxicity and immunogenicity. For these properties, polysaccharides found a wide application in nanotechnology.
Modified polysaccharides are manufactured to satisfy the demands of an industry of various branches; first of all, the food, pharmaceutical, cosmetic, pulp, textile, metallurgical and drilling industries. Among commercially available natural polysaccharides, starch, cellulose and pectins are the most common, but there is a wide area of potential applications waiting for easy access to other polysaccharides, such as carrageenans, xanthan gum, alginates, hyaluronan, chitosan, furcellaran, and so on. Considerable attention is being paid to eliminating traditional processes of manufacturing and using natural polysaccharides, in favor of modern solutions satisfying ecology and consumer demands.
This Special Issue aims to promote novel polysaccharide-based materials, including their synthesis, characterization, and potential 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. Applied Sciences 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 2400 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.
