摘要：
Facile green synthesis of stable silver nanoparticles in flower extract of Acmella oleracea and its dopamine sensing properties are reported. UV-visible spectroscopy, Fourier transform infrared (FTIR) spectroscopy, transmission electron microscopy (TEM) and particle size analysis were performed to ascertain the formation of silver nanoparticles. Aqueous dopamine sensing study of green synthesized silver nanoparticles was carried out. Further surface plasmon resonance (SPR) based fiber optic sensor has been fabricated using green synthesized silver nanoparticles as sensing material. The response time of the sensor is 6 min and the detection limit is 2 x 10(-7) M. (C) 2015 Elsevier B.V. All rights reserved.
