“…The cytotoxic effect of green synthesised AgNPs was evaluated by MTT assay against HeLa, MCF-7 and fibroblast normal cell lines exposed to different concentrations (2,5,10,25,50,100,150,200, 250 and 400 mg/ml) of AgNPs (Figure 9). AgNPs showed dose dependent cytotoxicity effect on all the three cell lines; all the three cell lines showed strong negative correlation between % cell viability and concentration of AgNPs; as concentration of AgNPs increased, the % cell viability decreased.…”

A novel approach for the utilisation of fruit waste is attempted in the present investigation. Mangifera indica seed aqueous extract was utilised for green synthesis of silver nanoparticles (AgNPs). The phytoconstituents in the seed acted as reducing and stabilising agent for AgNP formation. UV-Vis, Zeta potential, FT-IR, XRD, TEM, SAED, EDX analysis were used to characterise the green synthesised AgNPs. UV-vis spectra showed characteristic spectra at 450 nm; XRD and SAED confirmed the crystalline nature while TEM revealed the shape to be round and average size was 26.85 nm. FT-IR revealed functional groups like alcohol or phenols, carboxylic acids, ketones, amines, aromatic amines, aliphatic amines, alkyl halides and alkynes which were responsible for AgNP formation. The nanoparticles showed more antibacterial activity than antifungal activity and antibacterial activity towards Gram-negative bacteria was more than Gram-positive bacteria. Dose dependent antioxidant activity (DPPH, SO and ABTS) and dose dependent cytotoxic effect against HeLa, MCF-7 and normal fibroblast cell lines was envisaged. The green synthesised AgNPs exhibited three different bioactivities (3-in-1 system) i.e. dose dependent antimicrobial, antioxidant and cytotoxic activity. Fruit waste can be successfully utilised for silver nanoparticles formation which can be therapeutically useful and effective. HIGHLIGHTS Silver nanoparticles were synthesised from M. indica fruit waste i.e. seed Characterisation by spectroscopic techniques: UV-Vis, Zeta, FTIR, XRD, SAED, EDX and TEM analysis. Silver nanoparticles were 26.85 nm in size and round in shape Antimicrobial activity against 14 microorganisms Antioxidant activity in terms of DPPH, SO and ABTS Cytotoxic activity against HeLa, MCF-7 and Fibroblast normal cell lines ARTICLE HISTORY

“…The spatial distribution of Tetradenia riperia has been documented in various areas of African countries such as Rwanda 53 , Madagascar 54 , South Africa 55 , Uganda 56 and Tanzania 57 in which its medicinal potential has been attributed to abundant phytocompounds with antimicrobial effects 51 . Literature has reported the use of Tetradenia riperia leaves in the synthesis of various nanoparticles such as silver 58 , 59 . To the best of our knowledge, no study has reported on the synthesis of Ag–ZnO nanocomposites by using the aqueous leaves extract of Tetradenia riperia .…”

In this work, Ag–ZnO nanocomposites were prepared by a green synthesis route using aqueous leaf extract of Tetradenia riperia and investigated for antibacterial activity against Escherichia coli and Staphylococcus aureus. To optimize the synthesis of the Ag–ZnO, the effects of precursor concentrations, pH, and temperatures were studied. The Ag–ZnO nanocomposites were characterized by XRD, ATR-FTIR, FESEM, and TEM. Results show that the concentration of 8% Ag, the temperature of 80 °C, and a pH of 7–8 were optimal for the synthesis of Ag–ZnO nanocomposites. The XRD analysis showed the decrease in particle size of Ag–ZnO from 23.6 to 14.8 nm with an increase in Ag concentrations, which was further supported by FESEM analysis. TEM image of 8% Ag provides more information on the coexistence of Ag on ZnO where an average particle size of 14.8 nm was determined. The ATR-FTIR analysis confirmed the presence of phenolic compounds, which work as reducing and stabilizing agents. The antimicrobial activity results show that Ag–ZnO nanocomposite demonstrated a higher antimicrobial potency on E. coli than on S. aureus. Therefore, Tetradenia riperia leaf extract is a viable route for the synthesis of Ag–ZnO nanocomposites to be used for various applications, including water disinfection.

Thermochromic (TC) pigments offer significant potential for functional and aesthetic design of smart textile materials. In this study, TC (blue and red) pigments were applied to cotton fabrics and printed on especially designed childrenswear by flat screen printing technique. The antibacterial and ultraviolet protection functionalities have been implemented into the fabrics under study by using selenium nanoparticles. The factors affecting the printing process were studied and the optimum formula was screen printed to produce the pattern’s designs of childrenswear. After conducting several tests, the results showed a significant color-changing effect depending on temperature, the color fastness properties to light, wash, and rubbing were excellent. Antibacterial activity of printed fabrics was very good against Bacillus cereus and Escherichia coli bacteria and the anti-ultraviolet protection was found to be very good. The printed fabrics can be as protective childrenswear as shown in this work.
