Summary: This study successfully synthesized stable and dispersible gold nanostructures using pomegranate extract and a highly biocompatible polymer. The gold nanostructures can assemble with both chemotherapeutic and phototherapeutic drugs, and exhibit good photothermal response and nitric oxide release under laser irradiation. Preliminary biological experiments also demonstrated the inhibitory effect of these gold nanostructures on Hep-G2 hepatocarcinoma cell lines.

Summary: The CoFe2O4 nanoparticles were synthesized using an eco-friendly, simple, and inexpensive method, with the effect of different amounts of plant extract as a complexing agent on the final product's structure, morphology, and magnetic properties discussed. The synthesized NPs were characterized to investigate their size, shape, crystallinity, and magnetic properties, revealing a crystalline cubic phase with an average crystallite size of 15-30 nm. Analysis of the vibrating sample magnetometer (VSM) showed that the saturation magnetization and coercivity of the final product decrease with increasing amount of plant extract.

Summary: This study investigated the effects of ultrasound conditions on the characteristics and anti-inflammatory activity of gold nanoparticles synthesized using citrus peel extract. The results showed that temperature and power intensity influenced the particle size and anti-inflammatory activity of the synthesized nanoparticles. The nanoparticles synthesized with ultrasound had smaller particle size, higher yield, and greater anti-inflammatory activity compared to those synthesized without ultrasound.

Summary: The present study synthesized silver nanoparticles (Ag NPs) using a methanolic and aqueous extract of R. stricta. The Ag NPs were characterized using UV-visible spectroscopy, EDX, FESEM, and FTIR techniques. The Ag NPs exhibited SPR at 490-560 nm in the UV-visible spectra, and FTIR spectrum indicated the presence of various functional groups capping the nanoparticles. The Ag NPs had an average size of 20-35 nm and a spherical shape as confirmed by FESEM. The Ag NPs showed superior antioxidant, antibacterial, and antifungal activities compared to the plant extract.

Summary: The study aimed to determine the phytoconstituents in Triumphetta pentandra leaf extract and evaluate its in vitro antioxidant, antimicrobial, anticholesterol, and anti-diabetic properties. The extract showed the presence of tannins, alkaloids, phenols, steroids, saponins, and terpenoids, with a high total phenolic concentration. The extract exhibited strong antioxidant activity and demonstrated inhibitory effects on bacteria, fungi, cholesterol, and alpha-glucosidase. These findings suggest that Triumphetta pentandra could be used for the treatment of bacterial and fungal infections, hypercholesterolemia, diabetes, and other conditions related to oxidative stress.

Summary: Four three-dimensional hydrogen-bonded organic frameworks (HOFs) were synthesized, and a water-induced single-crystal-to-single-crystal transformation from GC-1 to GC-2 was observed. The ideal single-crystal sample of GC-2 exhibited ultrahigh proton conductivity along the [100] direction. When combined with Nafion, the composite membranes of GC-2, GC-3, and GC-4 showed significant enhancement of proton conduction.
