Special Issue Information
Dear Colleagues,
Microemulsions are continuously attracting the interest of researchers due to their unique properties, such as ultralow interfacial tension between oil and water phases, large interfacial area, thermodynamic stability, and ability to solubilize otherwise immiscible liquids. They are colloidal fluids containing one surfactant film, classified as oil-in-water (o/w), water-in-oil (w/o) or bicontinuous systems depending on their microstructure. The shape of the aggregates can be spherical, rod-like, and even worm-like, all of them characterized by having at least one dimension of about 10–100 nm. Some of the numerous applications of microemulsions relate to their potential uses as drug delivery systems, for the design of new composite materials, personal care and cleaning products, pharmaceutical formulations, chemical reaction media, and in the art restoration and petrochemical industry.
Nanoemulsions are kinetically stable liquid dispersions, consisting only of nanodroplets with sizes of a few hundred nm. Although they do not form spontaneously but are obtained by mechanical force, nanoemulsions are widespread in the food, pharmaceutical, and personal care industries due to their unique physicochemical properties and functional attributes, such as high surface area per unit volume, transparent appearance, tunable rheology, and advanced bioavailability.
I warmly invite scholars involved in the Colloids and Surface Science research areas to contribute original research papers as well as review articles to this Special Issue, in order to give the readers of Nanomaterials an updated and new perspective of these versatile colloidal systems for all kinds of applications, including both small- and large-scale processes.

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. Nanomaterials 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 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.
