Special Issue Information
Dear Colleagues,
The importance of nanomaterials increases year by year as they significantly contribute to improving the quality of human life. Nanomaterials are used in various types of consumer products, thus gaining new, unique properties. Silver and gold nanoparticles belong to one of the most widely used nanomaterials. They are characterized by high antimicrobial efficacy manifested in combating with bacteria, viruses, and fungi, as well as valuable optical, electrical, and magnetic properties dependent on their physicochemical properties, i.e., the shape of the particles, their size, stability, and the presence of ligands attached to their surface.
Silver and gold nanoparticles, which were previously integrated into the structure of consumer products, can, however, enter the natural environment and pose a threat to living organisms whose natural habitat is soil, water or air. Despite the beneficial properties of silver and gold nanoparticles, they may also exhibit uncontrolled toxic activity. Their penetration into the environment and specific reactivity may cause degradation effects.
Therefore, there is a need to present the results of original experimental or theoretical research undertaken to acquire new knowledge used to develop new nanomaterials technology, modify known processes for their preparation, in order to better control their properties or develop formulas that will not be characterized with harmful activity to the living matter or where this activity will be reduced while maintaining the functionality of materials and assessing the environmental risks associated with the use of metallic nanomaterials.
The long-term goal of this research is the possibility of safe use of nanomaterials while maintaining their beneficial properties. This can contribute to improving the quality of life while protecting the natural environment.
The subject matter of the Special Issue applies to new developments in:
- Green synthesis for receiving novel gold and silver nanomaterials;
- Challenges and opportunities in the production of gold and silver nanomaterials;
- Processes for obtaining stable suspensions and powders of silver and gold nanoparticles with controlled physicochemical and functional properties;
- Reaction systems used in the processes of obtaining nanoparticles;
- Characterization of physicochemical and functional properties of nanoparticles, and the influence of process parameters on these properties;
- Assessment of antimicrobial and catalytic properties of nanoparticles and ecotoxicological evaluation of nanoparticles against organisms representing different trophic levels of the food chain;
- Presentation of measurement techniques for analyzing the degree of exposure of organisms to the action of nanomaterials;
- Practical applications of silver and gold nanoparticles;
- High-purity nanomaterials;
- Composites, oxide systems, and hybrid materials containing silver and gold nanoparticles.

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. Materials 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 2600 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.
