Green Synthesis of Cupric Oxide Nanoparticles Using Water Extract of Murrya koenigi and its Photocatalytic Activity

Green and Traditional Synthesis of Copper Oxide Nanoparticles—Comparative Study

“…The size of the zeta potential gives information about the particle synthesized stability. For example, particles with high zeta potential exhibit increased stability due to larger electrostatic repulsion between particles [ 46 ]. While cCuO show a charge of −5.60 mV, wCuO, aCuO and eCuO had corresponding charges of −22.3, −16.5 and −15.6 mV, respectively ( Figure 6 ).…”

Innovative microwave-assisted biosynthesis of copper oxide nanoparticles loaded with platinum(ii) based complex for halting colon cancer: cellular, molecular, and computational investigations

“…45 Our findings showed ZP of −24.6 mV, which is consistent with the previous finding of similar CuO NPs prepared by algal-mediated synthesis and Murrya koenigi water extract-mediated synthesis, revealing similar negative charges of the nanoparticles. 46,47 On the other hand, the Cr@CuO NPs showed a ZP of −13.6 mV, revealing a lower negative charge after Cr entrapment. The reduction in negative charge is attributed to the loading of the positively charged Cr (resulting from the platinum drug's initial aquation reaction where the chloride groups are switched with the water molecules).…”

Functionalized thiazolidone-decorated lanthanum-doped copper oxide: novel heterocyclic sea sponge morphology for the efficient detection of dopamine

“…† The negative value represented the formation of hydroxyl groups on the CuO surface upon interaction with water. 43 This negative diffused layer of surface OH − contributes to robust sensing of positively charged DA. However, the zeta potential shifts to −6.3 mV in La@CuO, as shown in Fig.…”
