“…Studies have reported that many natural compounds, such as those derived from fungi, algae, bacteria, and plants, were used in green synthesis of AuNPs [7,8,9,10]. These natural compounds-mediated procedures for synthesis of AuNPs represent advantages over conventional chemical and physical methods, as they are simply, low-cost, energy-efficient, and nontoxic green routes [11,12,13,14]. In this regard, we focused our attention on natural polysaccharide extracted from seaweed, which is a proven source of bioactive compounds [15].…”

Gold nanoparticles (AuNPs) were synthesized using a facile solvothermal method with alginate sodium as both reductant and stabilizer. Formation of AuNPs was confirmed by UV-vis spectroscopic analysis. The synthesized AuNPs showed a localized surface plasmon resonance at approximately 520–560 nm. The AuNPs were characterized using transmission electron microscopy, X-ray diffraction and dynamic light scattering. Transmission electron microscopy revealed that the AuNPs were mostly nanometer-sized spherical particles. Powder X-ray diffraction analysis proved the formation of face-centered cubic structure of Au. Catalytic reduction of 4-nitrophenol was monitored via spectrophotometry using AuNPs as catalyst, and further a non-enzymatic sensor was fabricated. The results demonstrated that AuNPs presented excellent catalytic activity and provided a sensitive response to H2O2 detection.

“…Quinclorac remediation studies hardly use phytoremediation to its decontamination. In general, the studies use bioremediation with fungi and bacteria or different technologies as photodegradation, hydrolysis, and catalysts with nanoparticles (LANG et al, 2018;NAVARRO et al, 2009;SHI et al, 2017;YANG et al, 2020).…”

This study validated a simple, and fast method by High Performance Liquid Chromatography with Diode Array Detector (HPLC -DAD) for pesticide phytoremediation analysis. The method was developed in water and in a hydroponic medium. Sample extraction and concentration were performed by Solid Phase Extraction (SPE) with Strata C18-E type cartridges. The SPE-HPLC-DAD method was successfully applied in the detection and quantification of quinclorac, 2,4-D, propanil, bentazon, clomazone and tebuconazole in water and hydroponic medium for 14 days. The method presented excellent results with the linearity of 0.9969 - 0.9994 and the lowest limit of detection (LOD) and quantification (LOQ) of pesticides was 1.7 μg/L and 5.0 μg/L, respectively with RSD <11.92%. The average recovery obtained ranged from 77.62% to 109.73% and RSD <12.70%. A Lactuca sativa species promoted phytoremediation on the 7th day for 2,4-D and tebuconazole and on the 14th day for clomazone.

Nanotechnology has permeated all areas of sciences as one of the most propitious technology with the deployment of nanoparticles in environmental remediation and biomedical fields; their synthesis under greener conditions has been bourgeoned using microorganisms, plants, etc. to decrease the use of toxic chemicals. Synthesis of nanoparticles by exploiting microorganisms has opened up a new prospect at the interface of nanotechnology, chemistry, and biology enabling access via a biocompatible, safe, sustainable, eco-friendly, and reliable route; microorganisms offer crystal growth, stabilization, and prevention of aggregation thus performing a dual role of reducing and capping agent because of the presence of biomolecules such as enzymes, peptides, poly (amino acids), polyhydroxyalkanoate (PHA), and polysaccharides. Herein, the microorganisms-based synthesis of various nanoparticles comprising gold, silver, platinum, palladium, copper, titanium dioxide, zinc oxide, iron oxide, and selenium along with their appliances in waste treatment, biomedicine namely cancer treatment, antibacterial, antimicrobial, antifungal, and antioxidants, are deliberated.
