The copper nanoparticles (CuNPs) have attracted much attention due to their application in diverse fields. The applications of CuNPs depend on their physical and chemical properties. This study presents the first report for the use of medicinal fruit extract of Piper retrofractum Vahl as an eco-friendly reagent in the synthesis of CuNPs using copper sulfate as a starting material. Piper retrofractum Vahl extract was employed as a bioreductor as well as a capping agent in the formation of CuNPs. The reaction process was assisted by sonication and stirring. The influences of extract concentration, pH, temperature, and reaction time on the size of CuNPs were studied in detail. The morphology and structure of synthesized CuNPs were characterized by UV-Vis, FT-IR, SEM-EDS, TEM, and XRD. The UV-Vis measurement showed the surface plasmon resonance (SPR) peak at 234-255 nm, whereas FTIR characteristic peaks of metal-oxygen (Cu-O) were confirmed in the range 550-570 cm À1 and Cu-O-H bonds led to bending absorptions in the region 870-880 cm À1. The synthesized CuNPs possess the spherical shapes and high content of copper (70.3%) as confirmed by SEM-EDS. From the TEM micrograph, it can be seen that the particle size distribution of CuNPs has a high uniformity with a size of 2-10 nm under the optimum condition. The crystalline nature of CuNPs as confirmed by XRD showed the crystallinity phase of 26.4%. The synthesized CuNPs have relatively good stability and could inhibit Escherichia coli and Staphylococcus aureus. The results proved that Piper retrofractum Vahl fruit extract could be applied for a greener synthesis of CuNPs with high uniformity of particle sizes.

“…Metal NPs improve water and micronutrient imbibition, accelerate mobilization of reserves during the first stages of the germination process (Costa Da and Sharma, 2016) and increase germination vigour (Quiterio-Gutiérrez et al, 2019)[51] because of a greater activation of copper enzymes (Javed et al, 2017) and a fast adenosine triphosphate (ATP) production by the copper dependent enzyme cytochrome C oxidase (Ramzan et al, 2021). This process takes place when molecular oxygen (O2) reduction is catalyzed to water (H2O), generating an electric gradient used by the mitochondria (Kumar et al, 2020;Mehdizadeh et al, 2020).…”

Metal nanoparticles have many positive effects in improving crop production and productivity and allow for increased germination and rapid crop establishment under field conditions. The metallic nanoparticles applied in this study were copper oxide nanoparticles (CuONPs) biosynthesized using orange peel (Citrus X sinensis) as a reducing agent to avoid or reduce toxicity in wheat seeds and sprouts. This study determined the effect of CuONPs on germination, radicle and plumule length, as well as the production of phytochemical compounds in wheat sprouts. The seeds were treated with suspensions of CuONPs at the following concentrations: 0, 0.5, 1, 2, 4 and 6 mg mL-1. The results indicate that the use of low doses of CuONPs (0.5 mg mL-1), improved germination, vigor, plumule and radicle length, in addition to increasing the biosynthesis of phytochemical compounds in wheat shoots. A high concentration of CuONPs (6 mg mL-1) causes inhibitory effects due to Cu accumulation and phytotoxicity in plant tissue. The use of CuONPs for green synthesis is a viable alternative to obtain beneficial effects in germination and seedling development, as well as greater secondary metabolite production.

“…One of the new therapeutic trends in the oncology, for example, is related to the use of tiny particles with special features in terms of specificity and biological safety. The peculiarity of these molecules (nanoparticles) is mainly based on their small size and the versatility to act as transporters of any type of element and to interact with biomolecules present in different cellular locations, with properties such as a size smaller than 100 nm, as well as a contrast between rigidity and flexibility, giving them use in medicine, among other areas ( 77 , 78 ).…”

Sacha inchi (Plukenetia volubilis Linneo) is an ancestral plant originating in the Amazon jungle that has been adopted as a food source due to its high nutritional value, which has gradually been attributed with potential benefits for human health. Diverse prospective studies have evaluated the effect of consuming components from the plant, derivatives from its seeds, leaves and shell on preventing the risk of cardiovascular disease, chronic inflammatory disease, dermatitis and controlling tumor proliferation, especially given its recognized high content of essential fatty acids, phenolic compounds, and vitamin E, showing antioxidant, hypolipemic, immunomodulation, and emollient activity, as well as the capacity to remove heavy metals from aqueous solutions. This review offers a complete description of the information existing on the use and biological activity of P. volubilis L., based on its essentially lipid components and evidenced on its use in the field of human health, in prevention, therapeutic, and nutritional contexts, along with industrial uses, making it a promising bioresource.
