Product Number: VLSS002 Product Size: 20 mL Description: Silver prisms with hexagonal and triangular morphologies have large light absorption and scattering cross sections and broadband plasmonic peaks. These particles have average thicknesses of 5-8 nm and, depending on the size of the particles, their plasmonic peaks can span the visible to IR regions of the spectrum. These particles are suitable for bio-molecular detection, surface-enhanced Raman spectroscopy and photo-thermal cancer therapies.

Product Number: VLSS004 Product Size: 20 mL Silver prisms with hexagonal and triangular morphologies have large light absorption and scattering cross sections and broadband plasmonic peaks. These particles have average thicknesses of 10 - 40 nm+ and, depending on the size of the particles, their plasmonic peaks can span the visible to IR regions of the spectrum. Thicker entities can be created, which would be more accurately described as cube/bipyramids. These particles are suitable for bio-molecular detection, surface-enhanced Raman spectroscopy and photo-thermal cancer therapies. Properties: Visual Appearance Vibrant (Yellow to Violet) Particle Shape 2D Triangular Plates Plasmonic Peaks 500 - 900 nm Particle Size, TEM 25-200 nm width, 10- 40+ nm thick Size distribution Broad Concentration 0.25 mM of Ag Absorption 2.5 - 2.6 OD/cm Caution: For increased shelf-life, store between 4- 22 °C; do not freeze LSPR Wavelength Maximum (nm) options: VLS004-1: 500-510 nm; VLS004-2: 525-535 nm; VLS004-3: 550-560 nm; VLS004-4: 575-585 nm; VLS004-5: 600-610 nm; VLS004-6: 625-635 nm; VLS004-7: 650-660 nm; VLS004-8: For more wavlengths Contact Us

Product Number: VLSS003 Product Size: 20 mL Silver nanorods possess two tunable plasmonic peaks corresponding to the lateral and longitudinal modes of the nanoparticle. The pentagonal facets also possess very sharp edges which produce local high field strengths. These particles typically have diameters of ~40 nm with lengths varying from 50 nm to 300 nm. They exhibit a narrow lateral plasmonic peak at 425 nm, and a broad, tunable longitudinal mode ranging from 500 nm to 1300 nm.
