“…The shortening in the absorption peak at 3381.21 cm -1 indicates a reduction process of Cu 2+ ions into colloidal Cu 0 nanoparticles [13]. The shift in wavenumber between dragon fruit extract and CuNPs suggests an interaction of functional groups between red dragon fruit extract and CuNPs, where the O-H and C=O groups that may be contained in tannin compounds have specific absorption peaks in the order of 3500-3200 cm -1 and 1725-1705 cm -1 .…”

The effort of copper nanoparticle exploration for antibacterial cleaning agents needs to prevent infection or contamination of microorganisms such as bacteria and viruses due to its potential characteristic as an environmentally benign material. The synthesis of copper nanoparticles using 0.02 M Cu(NO3)2 as a precursor and red dragon fruit extract as a bioreduction agent has been conducted. The extraction process of red dragon fruit was done by the maceration method using methanol as solvent. Copper nanoparticles were prepared through green chemistry with the reduction method. The compound in red dragon fruit extract reduced Cu2+ to Cu. The experimental nanoparticle synthesis method was performed with a combination of red dragon fruit extract and Cu(NO3)2 solution mixed with a volume ratio of bioreductor extract toward Cu2+ precursor variation of 1:1, 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, and 1:9. The mixtures were stirred using a magnetic stirrer for 30 minutes and then incubated. The samples were characterized using UV-Vis (Ultraviolet-Visible), FTIR (Fourier Transform Infrared), and a digital microscope to observe morphology. The observation continued to assess its antibacterial activity and potency as an active disinfectant. UV-Vis analysis showed that the absorbance value for 30 minutes tended to be stable. Particle size estimation showed the smallest size of 122.12 nm at a volume ratio of 1:9. Functional group analysis using FTIR showed a shift in wavenumber between dragon fruit extract and copper nanoparticle (CuNPs), indicating a functional group interaction. The results of morphological analysis using a digital microscope showed that the particles with fine powder granules were produced with the composition of fruit extract: Cu(NO3)2 of 1:9. Antibacterial activity against Staphylococcus aureus and Escherichia coli indicated that the composition of Cu-nanoparticles of 1:9 had given an inhibition value.

Secondary metabolite compounds in plants act as bioreductors in the metal reduction process and complement inorganic reductants. This study studied the characteristics of copper nanoparticles using Carica Dieng (Carica pubescens) seed extract. The synthesis of copper nanoparticles was carried out using the green synthesis method by reducing CuSO4 10 mM with distilled water extract from Carica Dieng (Carica pubescens) seeds. The Synthesis was carried out with the ratio of the composition of the extract and CuSO4 solution 1:3 at pH 10. Nanoparticles were then characterized using UV-Vis spectrophotometer and PSA (Particle Size Analyzer) instruments. The characterization results using a UV-Vis Spectrophotometer showed a maximum absorption peak at a wavelength of 535 nm; the wavelength is included in the wavelength range of copper nanoparticles, which ranges from 500-700 nm. The particle size distribution analyzed using PSA shows an average size of 14.49 nm; this size is included in the range of nanoparticle sizes, which is between 1-100 nm, thus proving that nanoparticles have been successfully formed, the Poly Dispersity Index (PDI) value obtained is 0.1943 which indicates that the nanoparticle sample is categorized as homogeneous so that it has uniform size uniformity.
