ratio Due to the silver ions in the liquid, the entire stirring process is performed in a black glass bottle, and the temperature of the laboratory is approximately 20 °C. Electrodeposition of flower-like silver nanostructures. To keep the surface clean, the electrodep- osition process ...

The absence of inhibition zones for microbial growth after 48 h of incubation in the case of nanogold is not a result that excludes its antimicrobial activity. The antimicrobial properties of nanometals are influenced by their shape, size or surface-to-volume ratio. It also depends on the ...
Giusti 9, 50121 Firenze, Italy * Correspondence: galberti@unipv.it Abstract: Gold and Silver nanoparticles (AuNPs and AgNPs) are perfect platforms for developing sensing colorimetric devices thanks to their high surface to volume ratio and distinctive optical properties, particularly sensitive to ...
However, recent challenges involved controlling the size and composition ratio of two or more metals rather than those of their monometallic counterparts. This has led to different mixing patterns, such as core–shell, multi-shell, and intermixing, based on chemical ordering and geometric structure....
The cells were grown in flasks with filter screw caps (TPP, Trasadingen, Switzerland) until the monolayer confluence and sub-cultivated in complete medium in a 1:3 split ratio. Each HAp and AgHAp thin films, which covered a 0.5 mm square of Si, was placed in 24-well plates and exposed...
Many studies have investigated the effect of AgNPs in particle sizes ranging from 10 to 100 nm; however, nanoparticles larger than 100 nm might have different effects because they can induce different mechanisms of cellular uptake or have a different uptake ratio. We therefore conducted a cell ...
Microorganisms generally acquire resistance to antibiotics through the course of antibacterial therapy. Multi-drug resistance (MDR) has become a growing problem in the treatment of infectious diseases, and the widespread use of broad-spectrum antibiotics has resulted in the development of antibiotic ...
Nanosized metallic particles are unique and can considerably change physical, chemical, and biological properties due to their surface-to-volume ratio; therefore, these nanoparticles have been exploited for various purposes [7,8]. In order to fulfill the requirement of AgNPs, various methods have ...
