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.

The rapid development of the production of materials containing metal nanoparticles and metal oxides is a potential risk to the environment. The degree of exposure of organisms to nanoparticles increases from year to year, and its effects are not fully known. This is due to the fact that the range of nanoparticle interactions on cells, tissues and the environment requires careful analysis. It is necessary to develop methods for testing the properties of nanomaterials and the mechanisms of their impact on individual cells as well as on entire organisms. The particular need to raise public awareness of the main sources of exposure to nanoparticles should also be highlighted. This paper presents the main sources and possible routes of exposure to metal nanoparticles and metal oxides. Key elements of research on the impact of nanoparticles on organisms, that is, in vitro tests, in vivo tests and methods of detection of nanoparticles in organisms, are presented. Full article

The rapid development of medicine has forced equally rapid progress in the field of pharmaceuticals. In connection with the expensive and time-consuming process of finding new drugs, great emphasis is put on the design and use of metal and metal oxides nanoparticles in nanomedicine. The main focus is on comprehensive presentation of both physicochemical properties and the possibilities of using, in particular, silver (Ag) and gold (Au) nanoparticles, as well as zinc oxide (ZnO) and titanium oxide (TiO2) nanoparticles as drug carriers and in the treatment of cancer. An important element of this subject is the possibility of occurrence of toxic effects of these nanoparticles. For this reason, possible mechanisms of toxic actions are presented, as well as methods used to reduce their toxicity to ensure the safety of drug carriers based on these nanostructures. Full article
