“…Each fungus showed a distinct response to applied AgNPs depending upon the concentration and the rate of Ag ions released into the environment. 253 In 2010, Jaidev and Narasimha demonstrated the antifungal (A. niger) and antibacterial (Staphylococcus spp., E. coli, Bacillus spp.) activities of AgNPs.…”

Silver nanotechnology has received tremendous attention in recent years, owing to its wide range of applications in various fields and its intrinsic therapeutic properties. In this review, an attempt is made to critically evaluate the chemical, physical, and biological synthesis of silver nanoparticles (AgNPs) as well as their efficacy in the field of theranostics including microbiology and parasitology. Moreover, an outlook is also provided regarding the performance of AgNPs against different biological systems such as bacteria, fungi, viruses, and parasites (leishmanial and malarial parasites) in curing certain fatal human diseases, with a special focus on cancer. The mechanism of action of AgNPs in different biological systems still remains enigmatic. Here, due to limited available literature, we only focused on AgNPs mechanism in biological systems including human (wound healing and apoptosis), bacteria, and viruses which may open new windows for future research to ensure the versatile application of AgNPs in cosmetics, electronics, and medical fields.

“…AgNPs have been intensely studied due to their distinct antimicrobial activity. 12,[37][38][39][40][41] The antimicrobial ability of AgNPs results from the release of many silver ions (Ag + ). 42 Ag + is highly reactive against proteins because it can bind thiol groups (-SH) and cause structural changes in the microbial cell wall and nuclear membrane, leading to DNA condensation and cell death.…”

In this study, we evaluated the long-term antifungal effectiveness of 3 types of interior building materials (gypsum board [GB], cement board [CB], and softwood plywood [S-PW]) impregnated with thermally reduced silver nanoparticles supported by titanium dioxide (AgNPs/TiO ) under 95% relative humidity for 4 weeks. AgNPs/TiO was synthesized at 2 thermal reduction temperatures (TRTs, 120 and 200°C) with 2 different AgNP weight percentages (2 and 5 wt%). Four different silver-loading levels (SLLs, 0.025, 0.05, and 0.5 μg/cm and the critical concentration required to inhibit fungal growth on agar plates) and 3 fungal species (Aspergillus niger, Penicillium spinulosum, and Stachybotrys chartarum) were used in the experiments. Higher temperature reduced more ionic Ag to metallic Ag and increased the dispersion of Ag on TiO surface. The 200°C thermally reduced AgNPs/TiO demonstrated excellent antifungal efficiency: Mold growth was almost completely inhibited for 28 days at the low SLL of 0.5 μg/cm . Additionally, AgNPs/TiO exhibited higher antifungal activity on GB and CB than on S-PW. The stepwise regression results indicated that the TRT of AgNPs/TiO (β = -0.739 to -0.51), the SLL (β = -0.477 to -0.269), and the Ag level in the AgNPs (β = -0.379 to -0.136) were the major factors influencing antifungal activity and TRT might be the most significant one.

“…The pure metal is inactive; however, in the presence of moisture, silver readily ionizes to give silver cations, which show antimicrobial activity. Today, silver and silver nanoparticles, which have antifungal properties, are used in healthcare, in the food industry and in domiciliary applications, and they are commonly found in hard surfaces, materials, textiles and against indoor mould growth …”

“…Today, silver and silver nanoparticles, which have antifungal properties, [9] are used in healthcare, in the food industry and in domiciliary applications, and they are commonly found in hard surfaces, materials, textiles [10] and against indoor mould growth. [11] Many heterocyclic compounds containing benzimidazoles, which are the nucleus of albendazole (Fig. 1) are a subject of interest to Medicinal Chemistry because of the broad spectrum of their biological and pharmaceutical properties.…”

In spite of a large number of antibiotics and chemotherapeutics available for medical use, the emergence of old and new antibiotic resistance in the last decades revealed a substantial medical need for new classes of antimicrobial agents. In this paper we report the synthesis, characterization by elemental analysis, Fourier transform infrared and Nuclear magnetic resonance spectroscopies, and antifungal properties of two heteroleptic complexes of albendazole (albz) with Ag(I), using KSCN and o‐phenanthroline (phen) as the second ligand, respectively. Both complexes showed a moderate antifungal activity with all the assayed fungi, mainly Candida albicans and Candida tropicalis, that showed no activity against albendazole.
