“…It has a monoclinic crystal structure, whose space group is C 2/ c , and its lattice parameters are a = 4.6837 Å, b = 3.4226 Å, c = 5.1288 Å, and β = 99.54° [ 23 , 24 ]. At the nanoscale, CuO is characterized by being stable and having a long shelf life [ 25 ] and exhibits remarkable applications in catalysis [ 26 ], high-temperature superconductors [ 27 ], solar cells [ 28 , 29 ], chemical and gas sensors [ 30 ], and lithium ion batteries [ 31 ], among others. Apart from those, they can be used also in medicine as antibacterial [ 25 , 32 , 33 ], antiviral [ 34 , 35 ], and antifungal [ 36 , 37 , 38 ] treatments.…”
