Gold Nanoparticles
Gold nanoparticles (AuNPs) have garnered significant attention owing to their remarkable electronic, optical, thermal, and catalytic characteristics. These properties have made AuNPs a subject of keen interest across various disciplines, including physics, chemistry, biology, medicine, materials science, and several cross-disciplinary areas. Arcana Nano Particle is renowned for supplying a wide array of clients with monodisperse and unagglomerated gold nanomaterials.

Utilizations of Gold Nanoparticles
Applications in Diagnostics
Gold nanoparticles readily bind with antibodies and proteins, facilitated by the strong attraction between sulfhydyl (-SH) groups and the gold surface. These gold-biomolecule conjugates find extensive use in diagnostic settings, particularly in home and point-of-care tests like lateral flow assays, where their vivid red hue serves as a visual indicator.
Medical Implementations
Gold nanomaterials possess the capability to bind with biomolecules for precise targeting of cancerous cells. They find application in photothermal cancer therapy, leveraging their customizable optical characteristics to convert laser energy into heat, thereby selectively eliminating cancer cells.
Plasmonic Phenomena
Gold nanoparticles exhibit distinctive optical characteristics by supporting surface plasmons. At specific light wavelengths, these surface plasmons resonate strongly, leading to significant absorption or scattering of incident light. This phenomenon is robust enough to enable the imaging of individual nanoparticles as small as 30 nm in diameter using conventional dark field microscopy. Such profound interaction of metal nanostructures with light forms the cornerstone of the emerging field of plasmonics. Applications of plasmonic gold nanoparticles span diverse domains, including biomedical labeling, sensing, and detection. Moreover, the gold plasmon resonance serves as the foundation for advanced spectroscopic techniques like Surface Enhanced Raman Spectroscopy (SERS) and Surface Enhanced Fluorescence Spectroscopy, facilitating the detection of analytes with unparalleled sensitivity.

Gold Nanoparticle Density
Gold nanoparticle solutions are available in two concentrations: NanoXact (0.05 mg/mL) and BioPure (1 mg/mL). NanoXact solutions typically exhibit a ruby red or yellow/red color, depending on particle size, while BioPure solutions, being 20 times more concentrated, appear red or red/yellow and opaque. The highly concentrated BioPure formulations are particularly well-suited for applications requiring high concentrations or minimal residual reactants, such as nanotoxicology studies, environmental analyses, and lateral flow assays. Despite being made from a dense material, smaller gold nanoparticles remain uniformly suspended in solution. Although larger particles may settle over time, they can be easily redispersed by gently shaking the storage vial.
Non-agglomerating
In many cases, once nanoparticles bind together due to their diminutive size, lightweight nature, and exceptionally high surface area to volume ratios, separating them becomes a formidable challenge. Consequently, most reconstituted dried gold nanopowders typically consist of conglomerates comprising hundreds of individual nanoparticles. This aggregation significantly compromises the performance of numerous plasmonics and biomedical applications. At nanoComposix, we’ve pioneered customized processing methodologies that enable us to concentrate and refine nanoparticles without inducing aggregation. This breakthrough allows for seamless integration of nanoparticles into diverse systems by transferring them into various solvents.
