Special Issue Information

Dear Colleagues,

Nanotechnology plays an important role in improving drug delivery and therapeutic efficacy, offering targeted, localized, controlled and/or prolonged delivery of encapsulated drugs to the desired sites of action in the body while reducing unwanted side-effects and toxicity. Among the various drug nanoformulations that are clinically available, (phospho)lipid-based nanosystems are of particular importance due to their versatility and unique properties. They are biodegradable, biocompatible, and non-toxic and enable the incorporation of different drugs (active compounds, herbal substances, enzymes) varying in lipophilicity and size. (Phospho)lipid-based nanosystems include different types of liposomes that differ in size, morphology, design and surface properties, solid lipid nanoparticles, nanostructured lipid carriers, niosomes, nanoemulsions, and microemulsions. The physicochemical properties of (phospho)lipid-based nanosystems are determined by their composition and drug release profile, the stability of the nanosystem during storage, drug permeation through biological barriers/membranes and interactions with the cells, thus affecting drug bioavailability and therapeutic efficacy. Clinical applications of (phospho)lipid-based drug delivery nanosystems include a variety of nanoformulations for the treatment of infectious diseases, cancer, vaccination, inflammation and pain relief, and are applied by various routes of drug administration.

This Special Issue aims to present recent advances in (phospho)lipid-based drug delivery nanosystems and addresses their design, development, characterization, quality, safety, pharmacodynamic and pharmacokinetic properties.

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. Molecules 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 2700 CHF (Swiss Francs).

The drug delivery potential of liquid crystals (LCs) for ascorbyl palmitate (AP) was assessed, with the emphasis on the AP stability and release profile linked to microstructural rearrangement taking place along the dilution line being investigated by a set of complementary techniques. With high AP degradation observed after 56 days, two stabilization approaches, i.e., the addition of vitamin C or increasing AP concentration, were proposed. As a rule, LC samples with the lowest water content resulted in better AP stability (up to 52% of nondegraded AP in LC1 after 28 days) and faster API release (~18% in 8 h) as compared to the most diluted sample (29% of nondegraded AP in LC8 after 28 days, and up to 12% of AP released in 8 h). In addition, LCs exhibited a skin barrier-strengthening effect with up to 1.2-fold lower transepidermal water loss (TEWL) and 1.9-fold higher skin hydration observed in vitro on the porcine skin model. Although the latter cannot be linked to LCs’ composition or specific microstructure, the obtained insight into LCs’ microstructure contributed greatly to our understanding of AP positioning inside the system and its release profile, also influencing the overall LCs’ performance after dermal application.
