Porous Inorganic Drug Delivery Systems

Dear Colleagues,

In recent years, there has been considerable interest in the development of controlled drug delivery systems that are based on inorganic porous materials. In particular, mesoporous silica nanoparticles, zeolites mesoporous bioactive glasses, etc., have been used as promising carriers for drug delivery applications. According to IUPAC nomenclature, solid materials are classified as microporous (pore diameter less than 2 nm), mesoporous (pores are between 2 and 50 nm) and macroporous (pores greater than 50 nm). The main features of porous materials are the large surface area, their pore size and pore architecture, and their floating ability in biological media. Porous matrices can increase the solubility and bioavailability of poorly soluble drugs. Factors influencing the drug release mechanism include the pore size, interactions between the drug and the host network and stabilization of the amorphous drug phase. The aim of this Special Issue is to review the current research on inorganic materials as drug delivery systems.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized 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.
