Green synthesis of antibacterial and antifungal silver nanoparticles using Citrus limetta peel extract: Experimental and theoretical studies

“…Candida is a genus of yeast fungus belonging to the division Ascomycota [13] that can exist both as a commensal organism and an opportunistic pathogen in the human body [10,[14][15][16]. Candida species are normal microbiota components of the mucosal oral cavity, gastrointestinal system, and genitourinary tracts [17].…”

“…Hence, there is created a dangerous focus of inflammation that increases the risk of cerebral strokes, decompensated glycemia, and focal and autoimmune diseases [17]. Coupled with their drug resistance, biofilms lead to challenges in developing therapeutic approaches to prevent and cure oral infections [13].…”

“…Due to their unique physicochemical properties, beneficial interactions with living structures, and nontoxicity for healthy human tissues, AgNPs may represent key components in developing novel biomedical strategies [21,[70][71][72][73][74][75][76][77]. Researchers have reported considerable antifungal activity against Candida spp., with potent antibiofilm and cell disruption ability [13,27,[78][79][80]. Monteiro et al [81] indicated that AgNPs could be used in the treatment of denture stomatitis.…”

Thousands of microorganisms coexist within the human microbiota. However, certain conditions can predispose the organism to the overgrowth of specific pathogens that further lead to opportunistic infections. One of the most common such imbalances in the normal oral flora is the excessive growth of Candida spp, which produces oral candidiasis. In immunocompromised individuals, this fungal infection can reach the systemic level and become life-threatening. Hence, prompt and efficient treatment must be administered. Traditional antifungal agents, such as polyenes, azoles, and echinocandins, may often result in severe adverse effects, regardless of the administration form. Therefore, novel treatments have to be developed and implemented in clinical practice. In this regard, the present paper focuses on the newest therapeutic options against oral Candida infections, reviewing compounds and biomaterials with inherent antifungal properties, improved materials for dental prostheses and denture adhesives, drug delivery systems, and combined approaches towards developing the optimum treatment.

The green synthesis of nano-silver (NS) has gained increasing attention owing to its cost-effectiveness and environmental friendliness. Herein, we have described a novel one-step green preparation method of stable NS aqueous solution using Tollens reagent as the silver ion source, D-fructose as the reduction agent, and polyvinyl pyrrolidone (PVP) as the stabilizing and capping agent. The optimum preparation parameters were 40 mL 10 g L−1 PVP, 100 mL 0.116 mol L−1 D-fructose, and 200 mL 0.001 mol L−1 Tollens at a reaction temperature of 25 °C for 2 h. The prepared NS solution had a pH value of 7.10, with approximately spherical NS particles in the range of 13.95–87.36 nm. The resulting NS solution was stable under normal temperature, boiling water bath, and acidic environment; however, it did not exhibit stability under an alkaline environment. The NS solution had a remarkable absorption peak at 410 nm in its ultraviolet visible spectrum. Moreover, it exerted strong inhibitory effect on the growth of the bacteria isolated from the vase water of cut carnation ‘Prince’ flowers. These findings indicate that the obtained NS aqueous solution is potentially a practical and effective antibacterial agent for preserving cut carnations and other cut flowers.
