Sintesis Nanopartikel Emas Berbentuk Bipiramida Sebagai Bahan Pendeteksi Pest…

This study aims to synthesize and characterize nanobipiramide-shaped gold nanoparticles and then be applied as a test of sensitivity, stability and reability to detect chlorpyrifos in plasmonic sensors. Gold nanobipiramide has been successfully synthesized by seed mediated growth method. The results of the synthesis were characterized using FESEM, XRD, UV-Vis spectroscopy to see the optical pro…
