“…The diffraction peak of condition 100°C is sharp and higher than that synthesized at room temperature due to effect of the high temperature which made it easier to grow in a higher concentration of silver ion solution. Interestingly, most of researchers [27,32,33] that synthesized the nanoparticles using plant extracts seem to obtained a similar crystal structure. Scanning electron microscope was employed to analyze the shape and size of the silver nanoparticles that were synthesized by the green method.…”

Present investigation deals with the synthesis of silver nanoparticles (AgNPs) from Lycopersicon esculentum L.through simple and eco-friendly method and validation the capacity of nanoparticles to inhibit the virulence gene expression in Candida albicans. The nanoparticles thus obtained from Lycopersicon esculentum L. have been analysed and characterised by Scanning Electron Microscopy (SEM), UV-Vis spectrophotometer, X-ray diffraction (XRD) and Fourier Transform Infra-red Spectroscopy (FTIR) techniques. The average diameter of the AgNPs, whose morphology has been determined by SEM, was found to be 9.58 to 72.69 nm. The UV-vis spectrophotometer show peak located of silver nanoparticles at 340 nm. X-ray diffraction analysis also showed functional structure and pattern of silver nanoparticles. The FT-IR spectra indicated the role of different functional groups of reducing agent and silver nanoparticles. AgNPs at concentrations of 15 and 25% significantly downed expression of Sap1, LIP1 and Kex2, but had no effect on the expression of CDR1 gene. The findings of current study showed that tomato extract could be used as a green chemistry approach to produce AgNPs. It downed expression of Sap1, LIP1 and Kex2 genes, whereas had no effect on the expression of CDR1 gene, that it appears needs higher concentrations of AgNPs to inhibit its gene expression.

Background: Due to limited financial resources, poor access to basic oral care, and the high cost of restorative treatment, children of low-income nations have their general health, social well-being, and education opportunities affected by untreated dental caries. Arresting caries treatment (ACT) has been proposed to manage untreated dental caries in children of disadvantaged communities. Aims and objectives: The purpose of the present controlled clinical trial is to investigate the effectiveness of a new anticaries agent, nanosilver fluoride (NSF), preventing and arresting caries in children. Materials and methods: A total of 100 deciduous molars both maxillary and mandibular are randomly selected from 60 children of 4-9 years of age group, which were randomly divided into NSF experimental group and saline control group. Teeth were clinically diagnosed and treated by one masked examiner and followed up at 7 days, 5 months and 12 months by another calibrated examiner who was blinded to the type of treatment. The criteria of the ICDAS II were followed to determine the activity of lesion and the diagnosis of caries. The Pearson's Chi-square test was used to compare the groups during different follow-up examinations. Results: Seventy-eight percent of decayed teeth showed hard arrested dentine at 7 days; after 5-month analysis in the NSF group, 72.91% of the teeth showed arrested caries; and in the control group, only 34% of teeth showed arrest of caries. At 12-month analysis in the NSF group, 65.21% of teeth showed arrested cavities, and in the control group, 28.88% of teeth showed arrest of caries. Conclusion:The present study proves that NSF is an anticaries agent and presents a noninvasive option for caries arrest and treatment when applied directly to dentin caries lesions.

“…Various chemical and physical syntheses require high energy, highly toxic reducing agents, and stabilizing agents, which can cause harmful effects in humans. Differently, the green synthesis of metal nanoparticles, is an environmentally friendly bio reduction method that requires low energy to initiate the reaction (SINGH et al, 2018) This route has become more popular recently (RAJPUT et al, 2017), as it is an advantageous, sustainable option, and without the use of external stabilizing agents (ZHANG et al, 2016;SONG;KIM, 2009). Another important point is that the reducing agent is also responsible for coating the surface of the NP obtained, increasing its stability, and preventing its agglomeration.…”

Silver nanoparticles have been extensively researched and have several applications such as antimicrobial and anticancer, and can be used in the agricultural, biomedical, pharmaceutical, textile area, among others, but its toxicity is still little understood. Nanoparticles can measure between 1 – 100 nm and the most currently studied is the silver nanoparticle (AgNP). The main methods of synthesis are the chemical and the biogenic pathway, or green, which is less environmentally polluting, more environmentally friendly, and simpler, although standardization is more complex. Morphological and physical-chemical characteristics differ according to the synthesis method and, consequently, present different degrees of toxicity. Nanotoxicology studies the toxicity of nanoparticles on living organisms and scientists seek to know about the physical-chemical properties and their influence on interaction with the environment. It is known that there are several parameters that influence toxicity, such as dose, particle size, shape, morphology, surface chemistry, agglomeration/aggregation state, synthesis method, cell type and organism in which it is tested. Therefore, this article aims to address the main ways of synthesis of AgNPs, discuss the advantages and disadvantages of each method, the parameters that influence toxicity and examples of studies.
