About this item
Nanoparticle with a silica core and gold shell; high concentration with near-infrared absorbance
- High quality nanoparticles, precisely engineered and highly characterized
- Unagglomerated and monodisperse
- High concentration gold nanoshells (1 mg/ml gold basis concentration, ~25 OD)
- Used for optical filters, sensors, and photothermal therapies
Spherical gold nanoshell nanoparticles have a 120 nm silica core with a ~20 nm outer gold shell. Peak absorbance at 800 nm. Provided at 1 mg/ml gold concentration. Used in optical filters, sensing, and photothermal therapies. The carboxyl (lipoic acid) surface provide useful functionalization for conjugation to antibodies.
Each batch is extensively characterized to meet highest quality standards, ensuring reliable and reproducible results. All products supplied with batch-specific COA's with TEM, DLS, Zeta, and UV-Vis.
Colloidal gold has applications in Diagnostics, Lateral Flow Assays, Molecular Detection, Photothermal and Microwave-based Therapies, TEM labels, Nanotoxicology, Plasmonics (SPR / Surface Plasmon Resonance), and novel Color Enhancements and Pigments.
Custom formulations and ISO13485/cGMP compliant materials can be provided on request.
Due to temperature-sensitive nature of these materials, they will only be shipped during the week in order to prevent products from sitting in an uncontrolled temperature environment over the weekend.
