“…The amorphous nature of EGCG-TiO 2 NPs might be explained by the intercalation of catechins into the 3D structure formed by the intermediary products during condensation. In contrast with our results, other studies generated anatase or rutile TiO 2 NPs by green approaches depending on the calcination temperature applied [53,64]. However, our results were in accordance with those of Sankar et al [65] that produced amorphous TiO 2 NPs by using TTIP and Azadirachta indica aqueous leaf extract.…”

Nanoparticles (NPs) are conventionally produced by using physical and chemical methods that are no longer in alignment with current society’s demand for a low environmental impact. Accordingly, green synthesis approaches are considered a potential alternative due to the plant extracts that substitute some of the hazardous reagents. The general mechanism is based on the reducing power of natural products that allows the formation of NPs from a precursor solution. In this context, our study proposes a simple, innovative, and reproducible green approach for the synthesis of titanium dioxide (TiO2 NPs) that uses, for the first time, the major component of green tea (Camellia sinensis)—epigallocatechin-3-gallate (EGCG), a non-toxic, dietary, accessible, and bioactive molecule. The influence of EGCG on the formation of TiO2 NPs was analyzed by comparing the physicochemical characteristics of green synthesized NPs with the chemically obtained ones. The synthesis of bare TiO2 NPs was performed by hydrolysis of titanium isopropoxide in distilled water, and green TiO2 NPs were obtained in the same conditions, but in the presence of a 1 mM EGCG aqueous solution. The formation of TiO2 NPs was confirmed by UV-VIS and FTIR spectroscopy. SEM micrographs showed spherical particles with relatively low diameters. Our findings also revealed that green synthesized NPs were more stable in colloids than the chemically synthesized ones. However, the phytocompound negatively influenced the formation of a crystalline structure in the green synthesized TiO2 NPs. Furthermore, the synthesis of EGCG–TiO2 NPs could become a versatile choice for applications extending beyond photocatalysis, including promising prospects in the biomedical field.

“…Studies approved that the pericarp extract had anti-proliferative potential against MCF-7 cells by inducing apoptotic cell death. In addition, it induced apoptosis in human breast cancer (SKBR3) cells by investigation of morphological changes and oligonucleosomal DNA fragments (Ahn et al, 2022). Several studies showed as cytotoxic activity of Mangosteen Peel Extract (MPE) against MCF-7 cells designed by using MTT test, and were analyze using Probit analysis to induce IC50.…”

Breast cancer is the greatest common malignancy in females. This syndrome represents a serious public health problem that needs additional study to define its prediction and specific treatment. MCF-7 is a usually used breast cancer cell line that has been spread for many years by multiple groups. It shows to be a suitable model cell line for breast cancer studies worldwide, including those concerning anticancer. Anticancer and anti-inflammatory influences are important to treat the threats of chronic inflammation related with chronic diseases. Natural products have made and are remaining to make vital influences to the search for new anticancer agents. The use of natural foodstuffs in relationship with green nanoparticles has drawn attention because of its easy and eco-friendly protocol. Therefore, we aimed to investigate the antiproliferative activity of silver nanoparticles biosynthesized by mangosteen peel extract (MPE) on human breast cancer cell line (MCF-7) using [3-(4, 5-dimethylthiazolyl)-2, 5-diphenyl-tetrazolium bromide (MTT) method. In the present study serial concentrations (5, 10, 15, 50, 70, µg/mL) of cells biosynthesized silver nanoparticles by (MPE) was tested against MCF-7 cell lines showed a cytotoxic effects, morphological degeneration, damaging and has more effectiveness against breast cancer cells. The results showed a substantial a high reducing power, a sensible antiproliferative role and antioxidant activity. The results showed that silver nanoparticles biosynthesized by mangosteen peel extract (MPE) can be regarded as a suitable candidate for designing anticancer pharmaceutical preparations.

Titanium dioxide (TiO2) nanoparticles have gained significant attention due to their wide-ranging applications. This research explores an approach to functionalize Niobium Nitrogen Titanium Dioxide nanoparticles (Nb-N-TiO2 NPs) with Mentha arvensis ethanolic leaf extracts. This functionalization allows doped NPs to interact with the bioactive compounds in extracts, synergizing their antioxidant activity. While previous studies have investigated the antioxidant properties of TiO2 NPs synthesized using ethanolic extracts of Mentha arvensis, limited research has focused on evaluating the antioxidant potential of doped nanoparticles functionalized with plant extracts. The characterization analyses are employed by Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and Ultraviolet–visible (UV–Vis) spectroscopy to evaluate these functionalized doped nanoparticles thoroughly. Subsequently, the antioxidant capabilities through the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric-reducing antioxidant power (FRAP) assays have been assessed. Within functionalized Nb-N-TiO2, the FTIR has a distinctive peak at 2350, 2010, 1312, 1212, and 1010 cm−1 with decreased transmittance associated with vibrations linked to the Nb-N bond. SEM revealed a triangular aggregation pattern, 500 nm to 2 µm of functionalized Nb-N-TiO2 NPs. Functionalized doped Nb-N-TiO2 NPs at 500 µg mL−1 exhibited particularly robust antioxidant activity, achieving an impressive 79% efficacy at DPPH assessment; meanwhile, ferric reduction efficiency of functionalized doped Nb-N-TiO2 showed maximum 72.16%. In conclusion, doped Nb-N-TiO2 NPs exhibit significantly enhanced antioxidant properties when functionalized with Mentha arvensis ethanolic extract compared to pure Nb-N-TiO2 manifested that doped Nb-N-TiO2 have broad promising endeavors for various biomedicine applications.
