Pengaruh Waktu terhadap Kestabilan Nanopartikel Emas yang Disintesis Menggunakan Ekstrak Air Daun Jati (Tectona Grandis) Termodifikasi Mercaptopropionic Acid (MPA)

Abstract: Gold nanoparticles were synthesized using teak leaf water extract modified with Mercaptopropionic Acid (MPA). The observations for 6 days using UV-Vis spectroscopy, obtained stable gold nanoparticles which were characterized by the maximum wavelength absorption produced in the range of 538.5 nm - 541 nm.

“…While the modification of the GCE with bismuth also obtained high sensitivity with a LOD of 0.6 ppb, LOQ (Limit Of Quantitative) 2 ppb, and a concentration range of 2-12 ppb (Th Hue et al, 2020). However, modification using gold nanoparticles has a weakness, whereas the synthesis of gold nanoparticles takes much time, effort, and cost with not environmentally friendly (Yasser et al, 2019). In comparison, using bismuth is expensive and susceptible to temperature instability (Rossel et al, 2010).…”
