“…These methods can affect the surface reactivity and ion outlet in order to avoid any cytotoxic occurrence. One of the coating and surface passivation methods is sulfidation, for example, the existence of sulfide can avoid AgNO 3 toxicity ( Bowles et al, 2002 ). Also, Levard et al (2013) reported that sulfidation of silver NPs can hinder Ag ion mobility and reduce its dissolution rate.…”

Thousands of different nanoparticles (NPs) involve in our daily life with various origins from food, cosmetics, drugs, etc. It is believed that decreasing the size of materials up to nanometer levels can facilitate their unfavorable absorption since they can pass the natural barriers of live tissues and organs even, they can go across the relatively impermeable membranes. The interaction of these NPs with the biological environment disturbs the natural functions of cells and its components and cause health issues. In the lack of the detailed and comprehensive standard protocols about the toxicity of NPs materials, their control, and effects, this review study focuses on the current research literature about the related factors in toxicity of NPs such as size, concentration, etc. with an emphasis on metal and metal oxide nanoparticles. The goal of the study is to highlight their potential hazard and the advancement of green non-cytotoxic nanomaterials with safe threshold dose levels to resolve the toxicity issues. This study supports the NPs design along with minimizing the adverse effects of nanoparticles especially those used in biological treatments.

The silver atom has a single s electron hovering over a completed ten‐electron d shell, similar to that of copper and gold. Despite this similarity, there are signal differences in their properties. For silver, its single electron provides the best conductor of electricity, the highest electrical transmittance, highest thermal conductivity, highest light reflectivity, the second highest infrared reflectivity, etc. These outstanding properties have long been recognized and are essential to the most advanced technologies. However, it is only in the past decade that analytical techniques have become available to resolve the mystery of the catalytic action of silver. Raman spectroscopy revealed that the surface of silver is covered with a blanket of weak covalently bonded atomic oxygen, making silver an ever‐ready catalytic/reducing agent. This unique compound‐like combination of nascent oxygen and silver provides the bacteriologist and the organic chemist with a powerful tool for such processes as sanitation, heterogeneous oxidation, homogeneous oxidation, catalyzed group transfer reactions, etc. The following reports state current knowledge, offering insights as to the further possibilities of silver.

Zinc sulfide clusters were synthesized and characterized at low micromolar concentrations to assess the effect of metal-sulfide ligands on metal toxicity to aquatic organisms in oxic environments. Recommended preparation times are greater than 2 h initial reaction of equimolar sodium sulfide and zinc nitrate, followed by oxic aeration for 3 d. Ionic strength, pH, and anoxic stabilization time were found to be relatively unimportant in controlling the final yield. Adsorptive losses of zinc sulfide (ZnS) clusters to surfaces, however, were significant for a variety of vessel materials and membrane filters. Ionic strength and pH were found to be important factors controlling the extent of adsorptive losses with minimal loss for pHs greater than 9 and for soft waters. The Ag(I), Cu(II), and Hg(II) as metal sulfides completely suppress the analysis of sulfide, whereas Pb(II), Mn(II), and Co(II) partially suppress the analysis of sulfide by the methylene blue technique. Ultraviolet and fluorescence spectra are shown for synthesized ZnS clusters.
