Micro/Nano-Swimmers, Robots, and Motors: Fabrication and Applications

Dear Colleagues,

Nanomaterials are, due to their size, able to alter conditions of the surrounding matrix significantly, like adding magnetic properties to polymeric composite thin films. Furthermore, even they are small in form of thin films, they are able to entrap cargo to form drug delivery systems. Recent developments of drug delivery system based micro- and nanomotors show the possibility to finally reach applications, enabling new possibilities to combat diseases like cancer, as well as improve environmental remediation. Some first insights into these applications are displayed by catalytic nano-swimmers utilizing toxic substances as fuel in natural environments, as well as living-nanomotor composite systems able to bypass the blood brain barrier with little or no side effects.

This Special Issue of Nanomaterials aims to present the current state-of-the-art in the fabrication and use of nanoparticles and nanofilms as well as other nanocomposite systems in the field of drug delivery and guidance of micro-/nano-swimmer, robots, and motors. The importance of nanoparticles is based on the fact that they bridge clusters of atoms over microparticles up to solid materials. The importance of nanoparticles and nanofilms is highlighted especially by their surface properties, determining the behavior and biocompatibility of the micro- and nanomotors. In this context, microparticles and films are in the mesoscale bridging the gap to the macroscopic scale. In the present Special Issue, we would like to invite everyone who can significantly contribute to this research field with the aim of giving a balanced view of the current state-of-the-art in this discipline.

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.
