Special Issue Information
Dear Colleagues,
Recently developed modern technologies create an important task for researchers: to find selective materials for different substances. In order to improve selectivity and retention capacity, a new class of polymer materials has been developed, namely, molecularly imprinted polymers (MIPs). The most common definition for this new class is that they are polymers with voids with size, shape, and electronic environment complementary to the molecule used for their imprinting (i.e., the template). To understand the principle for obtaining the new material, imagine a coin being pushed into plasticine. After taking out the coin, an imprint remains in plasticine, having the size and the shape of the face of the coin that was pushed in. If one does the same with a molecule in a polymer matrix, an MIP is obtained, but at a molecular scale. In order to keep these voids unchanged after the extraction of the template, a very high degree of crosslinking or other structure stabilization is needed. Two kinds of preparation methods for MIPs have been developed: chemical methods, typically including polymerization (bulk, suspension, emulsion, precipitation, etc.), or sol–gel reactions and physical methods, referring mostly to phase inversion and which are more rarely used. MIP materials can have different shapes, such as irregular particles, beads, pearls, hydrogels, fibers, membranes, and films. The application of these new materials refers mostly to the water and air treatment, purification of a liquid, the separation of a substance from a complex mixture, analysis and sensing, but other applications such as catalysis or the slow release of bioactive substances are studied as well, explaining the need for this Special Issue of Applied Science. I am inviting you to publish your work in this Issue, and look forward to your contributions.

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. Applied Sciences 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 2400 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.
