“…Aside the previously mentioned usage, CuONPs showed exclusive anticancer, antimicrobial and antioxidant efficacy which renders them a promising tool for biomedical applications [ 15 , 16 ]. Different physical and chemical approaches like microwave irradiation, thermal decomposition, sol gel, colloidal thermal synthesis, sonochemical, hydrothermal, and quick precipitation have been reported for the synthesis of CuONPs with desired morphologies qualities [ 17 ]. However, these methods require labour-intensiveness, energy, intensive routes, expensive and hazardous chemicals [ 18 ].…”

Green synthesis of copper oxide nanoparticles using Bougainvillea leaves aqueous extract and antibacterial activity evaluation

“…Developing facile and green routes for synthesizing copper oxide nanoparticles are of importance and still a challenge for materials researchers. Plants such leaves, seeds, bark, flowers and fruits have been suggested as valuable alternatives to chemical and physical methods for synthesis of CuONPs, i.e., Polyalthia longifolia (Nagore et al, 2021), Ocimum basilicum (Altikatoglu et al, 2017), Catha edulis (Andualem et al, 2020), Juglans regia (Asemani and Anarjan, 2019), Ailanthus altissima (Awwad and Amer, 2020), Catharanthus roseus (Begum et al, 2019), Malva sylvestris (Benhammada and Trache, 2021), Adhatoda vasica www.bosaljournals/chemint/ editorci@bosaljournals.com nees (Bhavyasree andXavier, 2020), Beta vulgaris L (Chandrasekaran et al, 2020), Lantana camara (Chowdhury et al, 2020), Psidium guajava (Das and Goswami, 2019), Chamomile (Duman et al, 2016), Catha edulis (Gebremedhn et al, 2019), Punica granatum (Ghidan et al, 2016), Ziziphus mauritiana L.
