“…This technology has been reported to be beneficial in medicine [136][137][138][139][140], physics [136,141], genetics [142][143][144], and, most recently, in environmental sciences, among many other areas [123,[145][146][147]. We must highlight the fact that nanotechnologies have been reported as reliable [148], feasible [140], promising [149], practical [150], precise [151], cheap and effective [152], emerging [153], powerful [154], and economically feasible [155].…”

Since engineering nanoparticles (ENP) have been developed for using in industry and human commodities, is common to find their wastes and by-products from industrial chemical reactions, and it is also possible to find incidental nanoparticles in the environment. Currently, the remediation of polluted soils using nanotechnologies has become an emerging area with a huge potential to improve the performance of traditional remediation technologies. However, environmental concerns have also emerged regarding human and environmental health when nanotechnologies are released to ecosystems. The goal of this manuscript is to highlight the environmental benefits and risks that arise when nanotechnologies are used to remediate polluted soils. We searched Web of Science and Scopus in order to get latest updated information and patents pertaining to developments in the field of nanotechnologies for decontaminating soils. It has been determined that soil nanoremediation has some advantages, but it also has some disadvantages related to the final disposal of nanoparticles, nanomaterials, or nanodevices. Will some nanotechnologies be our pitfall? Nanoparticle toxicity has to be assessed and the standardization of techniques should be set by scientists and decision-makers worldwide. Cutting-edge knowledge regarding the use of nanoparticles to decontaminate soils has to move forward, but environmental quality, human health, and social welfare should also be ensured.

The aim of this study was to determine the validity and reliability of the Nanotechnology Awareness Scale (NAI) in Turkish culture. The study group consists of 624 biology, physics and chemistry teachers working in secondary schools in Antalya, Denizli, Burdur and Ankara. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were conducted in order to determine its structural validity. Cronbach-alpha and stratified-alpha coefficient values were calculated for the reliability of the sub-dimensions and the whole of the scale, respectively. In EFA, Kaiser-Meyer-Olkin (KMO) value was found to be 0.92 and the Bartlett Test result (912 91 = 6519.27, p <.00) was found significant. In addition, in original scale, a two-factor structure was found. This two factors solution explains 59.192% of the total variance. In CFA, factor structure of the scale was tested for two-factor solution as it was designed. According to the findings, it was found that the scale, containing 14 items with two sub-dimensions, had sufficient goodness of fit indices such as χ2/sd =1.344, RMSEA = 0.07, GFI = 0.97, CFI = 0.97, NFI = 0.90 and AGFI = 0.83. These goodness of fit indices shows that we have good model-data fit. The Stratified-alpha coefficient was found as 0.942 for the whole scale. Cronbach alpha coefficient was found as 0.935 and 0.805 for the awareness sub-dimension and exposure sub-dimension, respectively. As a result of the research, it was concluded that the Turkish version of the scale can be used as a valid and reliable measurement tool.

“…Therefore, the purpose of this work is to optimize a fast, facile, and non-expensive method for synthesizing AgNPs in non-specialized facilities. This easy-to-follow optimization protocol is mostly intended for biological research purposes, sanitation, and nanotechnology education [14, 16]. In the available literature, there are several facile methods for the synthesizing AgNPs [16–19].…”

Protocol optimization for a fast, simple and economical chemical reduction synthesis of antimicrobial silver nanoparticles in non-specialized facilities

et al. 2019

ObjectiveSilver nanoparticles (AgNPs) can be difficult or expensive to obtain or synthesize for laboratories in resource-limited facilities. The purpose of this work was to optimize a synthesis method for a fast, facile, and cost-effective synthesis of AgNPs with antimicrobial activity, which can be readily implemented in non-specialized facilities and laboratories.ResultsThe optimized method uses a rather simple and rapid chemical reduction process that involves the addition of a polyvinylpyrrolidone solution to a warmed silver nitrate solution under constant vigorous stirring, immediately followed by the addition of sodium borohydride. The total synthesis time is less than 15 min. The obtained AgNPs exhibit an aspect ratio close to 1, with an average size of 6.18 ± 5 nm. AgNPs displayed potent antimicrobial activity, with Minimal Inhibitory Concentration values of ≤ 4 µg mL−1 for Staphylococcus aureus and ≤ 2 µg mL−1 for Candida albicans. The resulting method is robust and highly reproducible, as demonstrated by the characterization of AgNPs from different rounds of syntheses and their antimicrobial activity.
