The synthesis of silver nanoparticles (AgNPs) using plant extracts has been extensively studied for the application of colorimetric detection of metal ions and antibacterial activity. In this study, silver nanoparticles were synthesized using Piper chaudocanum extract, application for the detection of Fe3+ ions. The structure, optical properties and morphology of AgNPs were determined by UV-Vis spectroscopy, FTIR, Raman, XRD, and SEM. The silver nanoparticles are spherical in shape, stabilized by organic compounds present in the Piper chaudocanum extract, with a size range of approximately 4-17 nm. The detection capability to Fe3+ ions by AgNPs was confirmed using UV-Vis spectroscopy. The silver nanoparticles can be utilized for highly sensitive colorimetric detection of Fe3+ with LOD and LOQ values of 0.372 μM and 1.244 μM, respectively. The concentration of Fe3+ in the domestic water sample determined by AgNPs was 30.0 μM. This result affirms the potential use of Piper chaudocanum extract for the synthesis silver nanoparticles and their application in the colorimetric detection of Fe3+ ions in real samples. Moreover, biosynthesized AgNPs exhibited good antibacterial activity.Tổng hợp xanh nano bạc (AgNPs) sử dụng dịch chiết thực vật đã được nghiên cứu rộng rãi nhằm ứng dụng để phát hiện màu các ion kim loại và hoạt tính kháng khuẩn.
