“…Today, medicinal plants are attractive for many researchers due to their low side effects, variety of effective ingredients, strong anti-inflammatory and antioxidant activity, and their ability to prevent tumor growth ( Chaleshtori et al, 2015 ; Wu et al, 2023 ). In this regard, in recent decades, plants have become globally significant sources of new anticancer drugs and antibiotics ( Kaur et al, 2023 ; Shehabeldine et al, 2023 ).…”

Introduction: Nanoemulsion and nanoencapsulation are attractive novel methods that can be used for incorporating active plant extracts in food preparations and pharmaceutical formulations. In the current study, we aimed to investigate the anticancer and antibacterial effects of hydroethanolic extracts of Nettle (NE), Wormwood (WE), and the combination of the two plants (CNWE), as well as their nanoemulsion forms (NN, NW, CNNW) and nanoencapsulation forms (CN, CW, and CCNW).Methods: The morphology and structure of the nanoemulsion and nanoencapsulation preparations were assessed utilizing dynamic light scattering (DLS) along with transmission electron microscopy (TEM). The antibacterial activity of the prepared formulations were assessed by determining minimum inhibitory concentration (MIC), zone of inhibition diameter, minimum bactericidal concentration (MBC), along with biofilm growth inhibition against Salmonaella typhimurium and Klebsiella. pneumoniae. The anticancer activity was evaluated via a MTT assay in the colon cancer cell line (HCT116).Results: The nanoemulsion and nanoencapsulation particle size varied between 10 and 50 nm and 60 and 110 nm, respectively. The MIC values were between 11.25 and 95 µg/mL along with MBC values between 11.25 and 190 µg/mL. The highest inhibition of biofilm formation was observed with CCNW against K. pneumoniae (∼78.5%) and S. typhimurium (∼73%). In descending order, the inhibition of biofilm formation was CCNW > CW > CN > CNNW > NN > NW > CNWE > NE > WE against the tested bacteria. The IC50 values for NE, WE, CNWE, NN, NW, CNNW, CN, CW, and CCNW were determined as 250, 170, 560, 380, 312, 370, 250, 420, and 700 µg/mL, respectively. Exposure to a high concentration of NW resulted in a significantly lower HCT116 viability compared to other groups. Taken together, CNNW, and CCNW showed the highest antibacterial and anticancer activitiy.Discussion: Nanoemulsion and nanoencapsulation were effective ways to increase the antibacterial and anticancer activity of the extracts and could be used in the food and pharmaceutical industries.

“…Tin oxide NPs (SnO 2 NPs) are n-type of semiconductor metal oxide with potential applications in various fields, including catalysis, biomedicine, and environmental remediation, to name a few. [15][16][17][18][19] More specifically, they have been investigated in a variety of organic synthesis reactions due to high catalytic activity, selectivity, and stability. For example, SnO 2 NPs have been served as a heterogeneous catalyst in coumarins, 20 imidazole derivatives, 21 benzimidazoles, 22 2H-indazolo [2,1-b] phthalazine-triones, 23 synthesis of 4, 5-dihydropyrrolo [1, 2-a] quinoxalines 24 reduction, coupling, cycloaddition reactions, among others.…”

Green nanocatalysts play a crucial role in organic synthesis. In this study, a novel approach utilizing marine diatom extract is presented for the production of tin oxide nanoparticles (SnO2 NPs). These NPs possess distinctive characteristics, including crystalline properties, a spherical shape, and an average size of 20 ± 2 nm. The reduction and surface coating of the NPs involve organic components derived from marine sources. The resulting SnO2 NPs serve as highly effective catalysts for the synthesis of chromeno[4,3‐b]quinoline derivatives, facilitated by ultrasound‐assisted reactions. This process demonstrates remarkable efficiency, yielding a variety of organic products with impressive results, reaching yields of 82–97% and requiring short reaction times. Moreover, the SnO2 nanocatalyst employed exhibits advantageous properties, such as low loading, durability, and the ability to be reused up to six cycles.
