Special Issue Information

Dear Colleagues,

This Special Issue came as the natural consequence of the great success of the previous one “Natural Polymers”.

Contributions are invited that specifically involve polymers of a natural or biological origin, namely proteins, nucleic acids, and polysaccharides. Of particular interest are research studies or review articles related to the following areas: (1) connections between polymer science fundamentals with the understanding and applications of natural polymers, including the structure, behavior and uses of natural polymers in solutions, complexes and at interfaces with other materials; (2) bioengineering applications of natural polymers, including tissue engineering, clinical medicine, as well as pharmaceutical and food technologies; and we particularly encourage; (3) novel applications of natural polymers, including their use in bioMEMs devices and nanotechnology as well as novel modifications of natural polymers to enhance their properties by functionalization, cross-linking, or forming composite or co-polymer structures with other materials.

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. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as 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 refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Polymers 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 1200 CHF (Swiss Francs).

The interest of chitosan for pDNA delivery applications lies with the ability to form positively charged nano-sized complexes (polyplexes) when positively charged amine groups bind with negatively charged pDNA. Although commercially available bulk chitosans were typically high molecular weight (Mn) and witha low degree ofdeacetylation(DDA), latter studies suggest low Mn (<150 kDa) and high DDA (>80%) chitosans (ULMWC) to increase transfection efficiency. The purpose of this review is to display an integrated review of all major areas of ultrapure low molecular weight chitosan (ULMWC)-based transfection, including production, ULMWC and polyplexes physicochemical characterisation, in vitro and in vivo assessment. In each, we present the impediments to efficient transfection and the strategies adopted over time to overcome these obstacules.
