Sintesis Gold Nanobipyramids Dan Aplikasinya Untuk Sensor Plasmonik

---

This study aims to synthesize and characterize Gold Nanobipyramids (GNBPs)
and to analyze their potential application to plasmonic sensors. Synthesis of
GNBPs uses the Seed Mediated Growth Method (SMGM). GNBPs were
characterized using Spectroscopy UV-Vis, X-Ray Difraction (XRD) and Field
Emission Scanning Electron Microscope (FESEM) to determine their optical
properties, crystaline and morphology. The UV-Vis absorption spectrum of
GNBPs shows that the t-SPR peak is at a wavelength of 573 nm and the l-SPR
peak is at a wavelength of 755 nm. The results of XRD characterization at a
diffraction angle of 30° - 70° showed 3 diffraction peaks at an angle of 2θ: 38.06°,
44.36° and 64.44°. The GNBPs have a Face Centered Cubic (FCC) structure with
crystal plane orientation (111), (200), and (220). From the FESEM photographs,
the percentage density of the sample surface is 78.86% and the average values for
length, width, and aspect ratio are 104.85 nm, 43.39 nm, and 2.46, respectively.
GNBPs are used as acetone and chlorpyrifos detection materials in plasmonic
sensor systems. Each spectrum reveals two resonant peaks, t-SPR peaks at
wavelength positions of 545.95 nm, 546.20 nm, and 546.40 for D.I. Water,
acetone and chlorpyrifos. moreover for the l-SPR peak, the position of each peak
is at the wavelengths of 803.40 nm, 803.45 nm, and 803.47 nm.
