摘要

Nanomaterial carbon quantum dots (CQDs) synthesized from various plants continue to be studied for their potential as antibacterials. The latest effort as a further development is to incorporate CQDs with metal elements. In this study, we report on CQDs nanomaterials made from Macaranga tanarius leaves synthesized hydrothermally and incorporated with silver nanoparticles (AgNPs) by sol gel-hydrothermal. The results of particle size analyzer (PSA) characterization showed that the incorporation of CQDs and AgNPs (CQDs@AgNPs) successfully obtained nano-sized antibacterials with a particle diameter of 46.60 nm ± 11.6. The incorporation also produced a unique morphology composed of fine grains in the form of nanoparticles. The redox property test using cyclic voltammetry showed that the antibacterial agent CQDs@AgNPs has reversible redox properties with a superior redox current value twice as large as CQDs. Based on the inhibition zone test of CQDs@AgNPs, high inhibitory activity values ​​were obtained for E. coli and S. aureus bacteria, which were 15.83 mm ± 0.19 and 19.15 mm ± 1.08, respectively. These results illustrate the potential of Macaranga tanarius leaves to be applied as precursor materials in the preparation of CQDs incorporated with metal materials to be an interesting study in the future.
