Special Issue Information
Dear Colleagues,
The concept of nanoencapsulation falls within the area of nanotechnology, which is defined as any technology related to materials, systems, and processes that operate at a scale of ≤100 nm, although, in practice, a maximum limit of 500 nm is accepted. Nanoencapsulation encompasses processes that have the advantage of providing protection to the component of interest, drugs, and bioactive compounds. Nanoencapsulation techniques and processes have emerged as promising tools in the pharmaceutical and nutraceutical sectors. An encapsulated bioactive would be trapped by a system that can preserve it from degradation, increasing its solubility and its bioavailability with the possibility of exerting a controlled release.
Biopolymers, i.e., polysaccharides, lipids, and proteins, are promising materials for constructing encapsulation matrices due to their characteristics such as abundance, biocompatibility, and non-toxicity. Furthermore, nanostructures could act as a versatile tool to enhance the therapeutic index of drugs, the bioavailability of which depends on the stability of the drug or bioactive in the oral, gastric, and intestinal environment, its solubility and mode of absorption, and, subsequently, its reach to the target organ.

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. 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.
