This work represents tunable copper oxide quantum dots (QDs) using an electrochemical synthesis in a mixture of electrolytes of citric acid (CA) and potassium chloride (KCl). The colloidal solutions showed a blue coloration, indicating quantum size effects and uniform dispersion of spherical QDs. The absorbance slightly decreased as the concentration of CA and KCl increased. PL studies indicated the maximum emission intensity at high CA and KCl concentrations due to great stabilization and surface-passivated quantum confinement effects. SAED confirmed polycrystalline structures of CuO and Cu2O depending on the concentration of CA and KCl. This possibility of tuning particle size and crystalline phases offers significant potential for advanced applications. For a demonstration of the QDs as an antibacterial agent, it demonstrates potential as an agent for inhibiting E. coli and S. aureus. Furthermore, the integration of the QDs with ZnO-based photocatalysts resulted in an enhanced photocatalytic degradation of methylene blue.

The study successfully synthesized copper oxide QDs via electrochemical methods, demonstrating control over particle size and crystalline phases through adjustments in citric acid and potassium chloride concentrations.These QDs exhibited promising antibacterial activity against both E.aureus, and their integration with ZnO photocatalysts significantly enhanced the degradation of methylene blue.The findings highlight the potential of electrochemically synthesized copper oxide QDs for diverse applications, particularly in antibacterial treatments and photocatalysis.

Penelitian lebih lanjut dapat dilakukan untuk mengoptimalkan konsentrasi elektrolit CA dan KCl guna menghasilkan QDs dengan ukuran dan fase kristal yang lebih seragam, sehingga meningkatkan efisiensi kuantum dan stabilitasnya. Selain itu, eksplorasi mekanisme antibakteri QDs terhadap berbagai jenis bakteri, termasuk studi tentang interaksi QDs dengan dinding sel bakteri dan dampak terhadap metabolisme sel, akan memberikan pemahaman yang lebih mendalam tentang potensi aplikasi biomedisnya. Terakhir, pengembangan material komposit baru yang menggabungkan QDs dengan matriks polimer atau material lain dapat membuka peluang untuk menciptakan sensor atau perangkat optoelektronik yang lebih sensitif dan efisien, serta memperluas cakupan aplikasi QDs di berbagai bidang teknologi.
