“…In order to overcome the recent global problems, health problems and wastes which have increased substantially in many parts of the world, innovative ways must be developed. Hence, nanotechnology occupies the interest of most researcher and so as to create trustworthy nanomaterial to solve those growing problems (Badawi and Zaher 2021;Badawi, et al 2021a;Badawi, et al 2021b). Previous studies focused on the synthesis of nanomaterials by chemical and physical approaches.…”

The antagonistic side effects of chemical medications led to the search for safe strategies such as biogenic agents. Correspondingly, this study aims to create biogenic, appropriate, auspicious and innovative therapeutic agents like Galaxaura elongata {GE}, Turbinaria ornata {TO} and Enteromorpha flexuosa {EF} macroalgae-based silver nanoparticles (Ag-NPs). The Ag+ reduction and the creation of Ag[GE]-NPs, Ag[TO]-NPs and Ag[EF]-NPs have been validated using UV–visible spectroscopy, Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM) and zeta potential analysis, and the chemical composition of macroalgae crude extracts was estimated through gas chromatography–mass spectrometry (GC–MS). Further, macroalgae-based Ag-NPs were tested for their free radical scavenging activity DPPH, ABTS, anticancer activity in human liver carcinoma (HepG2) cell line, distinctive inflammation forms and elevated α-amylase. Results showed that the biosynthesized Ag-NPs have unique mechanical and physicochemical characters attributed to their high relative surface area, nanosized dimensions and spherical shape. At dose of 200 µg/mL, the DPPH radical scavenging capacity was maximized with Ag[TO]-NPs (67.26%); however, Ag[EF]-NPs was the most potent as ABTs scavenger (97.74%). Additionally, Ag[GE]-NPs had the maximum proteinase inhibitory action with 59.78%. The 1000 µg/mL of Ag[GE]-NPs, Ag[TO]-NPs and Ag[EF]-NPs revealed significant inhibitions of cell growth of HepG2 resulting in cell viabilities 5.92%, 4.44% and 11.33%, respectively. These findings suggest that macroalgae bio-capped Ag-NPs have magnificent biological potentials for safe biomedical applications.

“…The results showed the enhanced color removal for the two examined adsorbents reached 84% for the AC and 80% for the nZVI at same operating conditions 0.8 g L −1 dose and 20 min contact time. A scaling up treatment study was investigated by Badawi et al 210 to assess the viability of using nZVI in a combined treatment system for the color removal from real textile wastewater. The results revealed maximum colour removal reached 98.4% at 0.8 g L −1 dose.…”

“…Before now, classical adsorbents namely: zeolites [ 25 ], synthetic resins [ 26 ], biowastes [ 27 ], biochar [ 28 ] and poly (methyl methacrylate) [ 29 ] have been randomly used to decontaminate wastewater. Generally, zeolites are aluminosilicate minerals that are hydrated to be in a microporous structure and used extensively as adsorbent material to remove hazardous contaminants from wastewater [ 30 , 31 ]. However, zeolites and the other identified adsorbents are limited by the difficulty in their separation process.…”
