Synthesis of The Tangerine-based Cdots and AgNp-Cdots Composite

Silver nanoparticles (AgNp) have been widely developed, one of which is an antibacterial agent. The ability AgNp to inhibit bacteria unquestionable. These properties and characteristics can be studied further by adding defects. defect used Cdots from tangerines. are new materials that synthesized natural unique properties. itself was the chemical reduction method with sodium citrate as a reducing agent, while hydrothermal method. results synthesis were analyzed using Fourier Transform Infrared (FT-IR) Absorption appears at wave number 1637 cm-1 indicates presence C=C, C=O bonds characteristic Cdots. For AgNp, absorption 593.11 Ag vibrations. Analysis UV-Vis spectrophotometer gave wavelength 431 nm absorbance AgNp-Cdots 0.723 422 0.285. Particle Size Analyzer (PSA) analysis showed had average size 38.7 PI 0.499 pure 51.8 0.566. Antibacterial activity against E. coli inhibition zone 2 mm 5 mm.
