Fabrication and UV-Vis Spectroscopic Properties of Novel Metal (Ag and Ag-Au) Introduced Silica-Coated Magnetic Beads |
| 초록 |
Our group have fabricated novel metal-introduced and thiol-modified silica-coated magnetic beads (TM-bead) and report UV–Vis spectroscopy as one of their optical properties. A total of six different types of Ag or Ag with Au introduced TM-bead were prepared, that is, firstly, Ag was introduced onto TM-bead either by immobilizing pre-synthesized Ag nanoparticles onto TM-bead or by growing Ag onto TM-bead. Subsequently, Au ions were introduced onto TM-bead@Ag NPs and TM-bead@AgG by growing. Similarly, Au NPs were immobilized onto TM-bead@Ag NPs and TM-bead@AgG. The materials were analyzed by an UV–Vis spectroscopy, a scanning electron microscope and an energy-dispersive X-ray spectroscopy. Obtained under a unified frame, the results provide reliable and valid information against those types of novel metal-based materials. The novel metal-immobilized magnetic beads also can be useful as plasmonic tunable magnetic beads in biological, material, and chemical applications. |
