“…Trypan blue staining was carried out to analyze the extent of the cellular damage. Trypan blue staining indicates the number of dead cells in the digestive tract after treatment with several concentrations of MnFe2O4@poly( t BGE-alt-PA). , The Drosophila’s larval stages, which are at a voracious feeding stage, showed no signs of toxicity even when exposed to MnFe2O4@poly( t BGE-alt-PA) at concentrations as high as 200 μM.…”

Nanocomposites have significantly contributed to biomedical science due to less aggregation behavior and enhanced physicochemical properties. This study synthesized a MnFe2O4@poly(tBGE-alt-PA) nanocomposite for the first time and physicochemically characterized it. The obtained hybrid nanomaterial was tested in vivo for its toxicological properties before use in drug delivery, tissue engineering fields, and environmental applications. The composite was biocompatible with mouse fibroblast cells and hemocompatible with 2% RBC suspension. This nanocomposite was tested on Drosophila melanogaster due to its small size, well-sequenced genome, and low cost of testing. The larvae’s crawling speed and direction were measured after feeding. No abnormal path and altered crawling pattern indicated the nonappearance of abnormal neurological disorder in the larva. The gut organ toxicity was further analyzed using DAPI and DCFH-DA dye to examine the structural anomalies. No apoptosis and necrosis were observed in the gut of the fruit fly. Next, adult flies were examined for phenotypic anomalies after their pupal phases emerged. No defects in the phenotypes, including the eye, wings, abdomen, and bristles, were found in our study. Based on these observations, the MnFe2O4@poly(tBGE-alt-PA) composite may be used for various biomedical and environmental applications.

“…Therefore, elimination of these metals from aqueous solutions was the top topic of many research works [13,[21][22][23][24]. There are several methods applied for wastewater treatment; such as coprecipitation [25], cation exchange [26], Ultrafiltration [27], reverse osmosis [28], nanofiltration [29], adsorption-reduction [30] and adsorption [31]. From economic and environmental points of view, application of adsorbent materials is advantageous over other methods due to ease of application, feasibility, broadness of adsorbents, recyclability, and lack of production of biproducts [32][33][34][35][36].…”

Hydrogel composites comprised of N,O carboxymethyl chitosan crosslinked with different weight ratios of acrylic acid and fabricated with nanoclay particle were prepared via gamma irradiation at 25 kGy irradiation dose. The prepared composites were coded as CsAA1Cl, CsAA2Cl and CsAA3Cl based on the weight ratio of acrylic acid to the chitosan derivative. The claimed hydrogels were characterized by FTIR, TGA and XRD. The TGA data implied that the incorporation of clay nanoparticles enhanced the thermal stability of the composites; the decomposition temperature increased up to 500 °C for CsAA3Cl. Three AFM outcomes were used to compare the surface features of the samples; topography, height and surface roughness. The topography data reveals that the nanoclay particles incorporated in CsAA3Cl are intercalated and exfoliated. Then, the optimized sorbent (CsAA3Cl) was investigated as green sorbents for chromium (VI) and lead (II). The data revealed that CsAA3Cl displayed maximum removal performance towards both lead and chromium with removal efficiencies 125 mg/g and 205 mg/g respectively at the optimum application conditions within 90 min only. Also, it was found that the optimum pH value was 9 for chromium and 8 for lead. The data proved that the adsorption of both cations followed pseudo-first order kinetic model. The prepared composites showed acceptable metal uptake capacity at three successive cycles. Graphical Abstract

A novel bio adsorbent was fabricated from turmeric, polyvinyl alcohol and carboxymethyl cellulose for MB dye removal. The physicochemical, antibacterial and biodegradable nature of the film was evaluated using scanning electron microscopy, optical microscopy, universal testing machine, water contact angle, thermogravimetric analysis, Fourier transform infrared spectroscopy, X-ray diffraction, agar disc diffusion method and soil degradability. The inclusion of turmeric into PVA/CMC film improves the biodegradability, antibacterial activity and thermomechanical property of the films. PVA/CMC/TUR film displayed good MB adsorption capacity (qe: 6.27 mg/g) and maximum dye adsorption (R%; 83%) and was achieved at initial dye concentration of 10 mg/L with contact time 170 min at room temperature. The adsorption data of MB on PVA/CMC/TUR film was evaluated using four models Langmuir, Freundlich, Temkin and D-R isotherms. The different kinetic of adsorption (pseudo-first order, pseudo-second order and intraparticle diffusion model) was also applied for adsorption of MB on the films. The experimental result suggests that PVA/CMC/TUR films are an alternate cheap adsorbent for water treatment.
