Special Issue Information
Dear Colleagues,
Recent advances in antibacterial nanomaterials have opened new pathways to combat microbial resistance and infections. Nanomaterials such as silver, zinc oxide, copper oxide, titanium dioxide, and carbon-based nanostructures exhibit strong antibacterial properties due to their high surface area, enhanced reactivity, and ability to interact with bacterial membranes.
They function through various mechanisms: releasing metal ions that disrupt cell metabolism, generating reactive oxygen species (ROS) that damage cellular components, and physically damaging bacterial membranes. Some nanomaterials can also interfere with DNA replication or protein synthesis, inducing bacterial death.
Multifunctional and hybrid nanomaterials are also being developed, combining antibacterial activity with other properties, such as anti-inflammatory or wound-healing effects. Surface modification and controlled release systems have further improved the biocompatibility and efficacy of these nanomaterials.
Furthermore, green synthesis methods are garnering interest as they provide the means to produce nanomaterials in an environmentally friendly and sustainable manner, using plant extracts or microorganisms.
Despite significant progress, challenges remain regarding the long-term toxicity, environmental impact, and large-scale production of these nanomaterials. Currently, research is focused on addressing these issues and developing safer, more effective antibacterial solutions for medical devices, coatings, textiles, and water purification systems.

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. Molecules 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 2700 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.
