Responsive Polymer Nanoparticles and Nanocomposites

Dear Colleagues,

This Special Issue is focused on the most recent advances in the synthesis, characterization, and applications of polymer-based responsive nanomaterials and nanocomposites, whose properties and functions can be controlled, even remotely, by external stimuli. The trigger signal can be induced by physical (temperature, mechanical forces, and electromagnetic radiation), chemical (pH, ionic strength, and solvent), or biological (enzymes and receptors) changes in the external environment. Progress in this field is rapidly expanding, and nanostructured systems based on responsive materials hold great promise for a breakthrough in materials science, for environmental, health, and biomedical applications.

A large number of smart polymer-based nanomaterials elicit a transition in solubility or conformation when they are in a liquid environment, resulting in the formation or disruption of nanosized supramolecular assemblies. Among them, smart nanocarriers developed to deliver drugs to specific cell types or tissues, with improved therapeutic activity and reduced side effects, have a key role. However, responsivity in solvent media can be also exploited for water purification, adaptive catalysis, sensing, and advanced coating applications.

Nonetheless, in this Thematic Issue, we also invite contributions dealing with responsive polymer-based nanostructured materials designed for advanced structural applications, including self-healing and shape memory materials.

We are grateful to the authors who will participate in this issue of Nanomaterials, and we hope that all articles herein will contribute to the development of this fascinating research and innovation field.

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 250 words) can be sent to the Editorial Office for assessment.

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 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.
