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....
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 ...
Thus, large surface to volume ratio and high-atomic-density {111} facets perhaps enhanced the bacterial killing efficiency of S4 as compared to S2. Moreover, the smaller-sized spherical AgNPs (S4) were more effective to penetrate inside the bacteria as compared to the larger triangular-shaped ...
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 ...
