Special Issue Information

Dear Colleagues,

Molecular engineering is opening up new possibilities for producing materials with tightly engineered applications. Using this approach, it is possible to obtain nanomaterials that are much more effective and precise than those obtained by classical wet chemistry methods.

Undoubtedly, the most important applications of nanomaterials, especially functional ones, are in the biomedical and environmental fields. Materials containing functional groups precisely located inside the nanostructure can effectively eliminate bacteria, reach specific tissues, and catalyze tissue regeneration processes. Moreover, such precise structures can successfully capture heavy metal ions or harmful molecules, contributing to water and soil protection.

This Special Issue focuses on nanomaterials and functional nanomaterials for biomedical and environmental applications. We will be accepting original research articles, comprehensive reviews, and new communications on the synthesis, study, and applications of such materials in bacterial eradication, tissue healing, anticancer therapies, and environmental protection in the broadest sense, focusing on water and soil remediation. However, we are also open to interesting articles from outside this 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 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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

The recent COVID-19 pandemic has made the public aware of the importance of combating pathogenic microorganisms before they enter the human body. This growing threat from microorganisms prompted us to conduct research into a new type of coating that would be an alternative to the continuous disinfection of touch surfaces. Our goal was to design, synthesise and thoroughly characterise such a coating. In this work, we present a nanocomposite material composed of a thin-layer mesoporous SBA-15 silica matrix containing copper phosphonate groups, which act as catalytic centres responsible for the generation of reactive oxygen species (ROS). In order to verify the structure of the material, including its molecular structure, microscopic observations and Raman spectroscopy were performed. The generation of ROS was confirmed by fluorescence microscopy analysis using a fluorogenic probe. The antimicrobial activity was tested against a wide spectrum of Gram-positive and Gram-negative bacteria, while cytotoxicity was tested on BALB/c3T3 mouse fibroblast cells and HeLa cells. The studies fully confirmed the expected structure of the obtained material, its antimicrobial activity, and the absence of cytotoxicity towards fibroblast cells. The results obtained confirmed the high application potential of the tested nanocomposite coating. Full article
