Gold Nanotriangular Plates

Product Overview

Gold nanotriangular plates are triangular-shaped gold nanoparticles, synthesized using a seed growth method and surface-modified with cetyltrimethylammonium bromide (CTAB), imparting a positive charge. This material has vast potential in nanotechnology and materials science, with unique optical absorption and scattering properties, particularly in the near-infrared region. Gold nanotriangular plates are promising for use in optical imaging, photothermal therapy, and biosensing.

Features

• Optical Properties: Gold nanotriangular plates exhibit unique optical absorption and scattering characteristics, especially in the near-infrared region, making them ideal for optical imaging and photothermal therapy.
• Surface Plasmon Resonance (SPR): These nanoparticles have distinct SPR peaks. By adjusting the size and shape of the nanoplates, the SPR peak position can be tuned for different applications.
• Enhanced Local Electromagnetic Field: The sharp edges of the gold nanotriangular plates generate strong local electromagnetic field enhancement, which is highly beneficial for surface-enhanced Raman scattering (SERS) and biosensing applications.
• Photothermal Stability: Gold nanotriangular plates demonstrate excellent photothermal stability, making them effective for photothermal therapy, particularly in the treatment of tumors.

Applications

• Imaging Technologies: Gold nanotriangular plates can improve the resolution and contrast of optical imaging in optoelectronics, optical sensing, and imaging fields.
• Photothermal Therapy: Due to their strong absorption in the near-infrared region, gold nanotriangular plates are well-suited for photothermal therapy. They generate heat upon laser irradiation, aiding in tumor treatment and other therapeutic applications.
• Drug Delivery: As drug carriers, gold nanotriangular plates utilize their surface modification for targeted drug delivery and controlled release, enhancing the precision and effectiveness of treatments.
