Dear Colleagues,

Despite the variety of treatment methods of wounds and scars after burns, there are still few effective formulations that can be used in non-invasive therapy. Out of many preparations that are applied topically to the skin after burns, as well as in the case of slow-healing wounds, the most common forms available on the cosmetics and pharmaceutical market are classic emulsions (including lotions and balms ), gels, ointments, and aerosols.

In recent years, there has been significant development of nanomedicine and nanotechnology in the treatment of wound infections. Nanostructured (as well as hydrogel matrix) systems are effective media for the active and medicinal substances used to treat bacterial infections and to stimulate wound healing.

The combination of nanocarrier and hydrogel matrix offers many benefits as a transdermal formulation, such as controlled drug delivery and easy administration, thus enhancing patient compliance. Moreover, this solution provides improvement in rheological and sensory properties of the nanocarriers and facilitates its application to the skin. The addition of rheological modifiers allows one to prolong the contact time of preparation with the skin and to increase the skin hydration level by forming a hydrophilic film on the skin surface and reducing the transepidermal water loss. This is a very important aspect in skin regeneration. To summarize, the hybrid systems of the nanocarrier–hydrogel matrix seem to be an extremely interesting solution in wound treatment.

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.
