The most prominent strategy in modern chemistry focuses on molecular recognition for molecules and ions but also supramolecular complex systems. Thus, biomimetic methods are designed which imitate nature. The bottle neck of synthetic routes—costs for man power and expensive chemicals—is bypassed by molecular imprinting which leads to molecularly imprinted polymers (MIPs). This synthetic strategy is based on carbon chemistry using template synthesis combined with polymer chemistry. The molecule of interest is wrapped by monomers or oligopolymers followed by polymerisation. Stereochemically stable structures are generated by using multifunctional monomers as cross linkers to form rigid polymers. The template can be removed by evaporation or dissolution. A host is synthesized in this way, then the guest can be reversibly included.
Analytical applications for MIPs are obvious; commercially, progress is made especially for solid phase extraction to guarantee a selective enrichment by sample preparation. Further straightforward developments are the design of separation materials for HPLC via MIPs. More chances arise for MIP design as coatings for sensors. Thus, lean molecules; polymer particles up to viruses and bacteria; and other cells can be adhered to MIPs. In this way, synthetic antibodies can be realized. Even catalytic MIPs which imitate antibodies and enzymes are of increasing interest. The binding of molecules and particles to MIPs makes it possible to design selective delivery systems, especially for drugs.

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 papers will be 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. C is an international peer-reviewed open access quarterly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) is waived for well-prepared manuscripts submitted to this issue. 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.
