In this study, Mitragyna parvifolia plant bark an aqueous extract which provides cost-effective, eco-friendly process, less time consuming, an environmentally benign, easy and proficient way for the synthesis of copper nanoparticles. Mitragyna parvifolia plant bark was collected from virpur hills forest area. The Mitragyna parvifolia plant bark extract was prepared in de-ionised water and used for the green synthesis of copper nanoparticles. The color change of the solution dark brown from pale yellow colored, this confirms that there is a formation of copper nanoparticles. The green synthesised copper nanoparticles were characterized by UV-Visible spectroscopy, FT-IR, XRD, SEM, TEM and their antimicrobial activity was investigated. From UV-Visible spectrophotometer result was confirmed the reduction of copper sulphate to copper nanoparticles. FTIR analysis was confirmed the bending vibrations and stretching bonds present in the sample. Spherical shape was finding out by XRD and the size of the particle was analyzed with the help of Scanning Electron Microscopy. The antibacterial activity experiment against Escherichia coli gram-negative and Bacillus subtilis gram-positive bacteria by agar well method and the maximum zone of inhibition was higher in gram-positive bacteria compared to gram-negative bacteria. The green synthesised copper nanoparticles proved to be potential candidates for medical application antimicrobial activity is highly essential.

The green synthesised copper nanoparticles were characterised by UV-visible spectroscopy, FT-IR, XRD, SEM, TEM and their antimicrobial activity was also investigated. UV-visible spectral result confirmed the reduction of copper sulphate to copper nanoparticles. FTIR analysis also supported for the formation of copper nanoparticles. Crystallinity of Cu NPs was find out by XRD study and the morphology of the particles was analysed with the help of scanning electron microscopy and found spherical in nature. The antibacterial activity experiment done against Escherichia coli, gram-negative and Bacillus subtilis, gram-positive bacteria by agar well method and the maximum zone of inhibition was higher in gram-positive bacteria compared to gram-negative bacteria. The green synthesised copper nanoparticles proved to be potential candidates for medical application where the antimicrobial activity is highly essential.

Copper nanoparticles (CuNP) were obtained by a green synthesis method using cotton textile fibers and water as solvent, avoiding the use of toxic reducing agents. The new synthesis method is environmentally friendly, inexpensive, and can be implemented on a larger scale. This method showed the cellulose capacity as a reducing and stabilizing agent for synthetizing Cellulose–Copper nanoparticles (CCuNP). Nanocomposites based on CCuNP were characterized by XRD, TGA, FTIR and DSC. Functional groups present in the CCuNP were identified by FTIR analysis, and XRD patterns disclosed that nanoparticles correspond to pure metallic Cu°, and their sizes are at a range of 13–35 nm. Results demonstrated that CuNPs produced by the new method were homogeneously distributed on the entire surface of the textile fiber, obtaining CCuNP nanocomposites with different copper wt%. Thus, CuNPs obtained by this method are very stable to oxidation and can be stored for months. Characterization studies disclose that the cellulose crystallinity index (CI) is modified in relation to the reaction conditions, and its chemical structure is destroyed when nanocomposites with high copper contents are synthesized. The formation of CuO nanoparticles was confirmed as a by-product, through UV spectroscopy, in the absorbance range of 300–350 nm.
