Small Particle Gold Nanotriangles

Product Overview

Gold nanotripods are triangular-shaped gold nanoparticles prepared using a seed growth method and surface-modified with cetyltrimethylammonium bromide (CTAB), imparting a positive charge. Their unique geometry and surface modification make them highly significant in nanotechnology and materials science. Gold nanotripods exhibit notable optical properties and surface plasmon resonance (SPR) effects, particularly in the near-infrared region, with strong optical absorption and scattering characteristics. These properties offer vast potential for diverse applications.

Features

• Optical Properties: Gold nanotripods exhibit intense optical absorption and scattering in the near-infrared region, making them ideal for optical imaging and photothermal therapy.
• Surface Plasmon Resonance (SPR): These nanoparticles possess distinct SPR peaks, and by adjusting their size and shape, the SPR wavelength can be tuned.
• Enhanced Local Electromagnetic Field: The sharp edges of the gold nanotripods generate strong local electromagnetic field enhancement, which is valuable for surface-enhanced Raman scattering (SERS) and biosensing applications.
• Photothermal Stability: In photothermal therapy, gold nanotripods demonstrate excellent photothermal stability, efficiently converting light energy into heat.

Applications

• Imaging Technologies: They improve the resolution and contrast of optical imaging, making them widely applicable in optoelectronics and optical sensing fields.
• Photothermal Therapy: Due to their strong optical absorption in the near-infrared region, gold nanotripods can be used in photothermal therapy to treat tumors, generating heat upon laser irradiation for therapeutic effects.
• Drug Delivery: As drug carriers, gold nanotripods utilize their surface modification to enable targeted drug delivery and controlled release, enhancing treatment precision and effectiveness.
