Special Issue Information
Dear Colleagues,
Natural biopolymers are promising candidates for revolutionizing the therapeutic applications of drug and gene delivery owing to their numerous advantages, including, but not limited to, low immunogenicity, biocompatibility, and biodegradability. Traditional delivery systems often face limitations such as poor bioavailability, rapid clearance, and off-target effects when applied to drug and gene delivery in order to specific target sites. Natural biopolymers, derived from biological sources such as proteins, polysaccharides, and nucleic acids, offer a promising alternative for overcoming these challenges. Additionally, the ability to engineer these biopolymers in order to respond to specific environmental cues, such as pH, temperature, or enzymatic activity, can enhance site-specific drug release and improve the efficiency of gene transfection. By regulating the inherent properties of these biopolymers, advanced delivery platforms could be designed with enhanced efficacy and reduced toxicity.
The ability of natural biopolymers to self-assemble into nanoparticles, micelles, hydrogels, and other carrier systems enables the controlled release of therapeutic agents. These biopolymers can also be functionalized using targeting ligands, enabling site-specific drug delivery, minimizing off-target effects, and augmenting their therapeutic efficiency.
Natural biopolymers, such as DNA and RNA-based polymers, are excellent candidates for delivering genetic material into target cells. Their biocompatibility and ability to protect nucleic acids from enzymatic degradation are critical factors in successful gene delivery. The applicability of these natural biopolymers could be enhanced by modifying biopolymers so as to boost cellular uptake and endosomal escape.
This Special Issue aims to provide an overview of the recent advancements made with regard to utilizing natural biopolymers for drug and gene delivery, highlighting their potential to address existing challenges in conventional delivery systems and pave the way for personalized and targeted therapies.

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. Pharmaceutics 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 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.
