Silver Nanoparticles
Silver nanoparticles (AgNPs) are increasingly sought after for their exceptional chemical stability, catalytic efficiency, distinctive localized surface plasmon resonance, and superior conductivity. Moreover, studies have revealed that reactive oxygen species (ROS) generated on the AgNPs’ surface or by the liberated silver ions can trigger cell death in both mammalian and microbial cells under specific conditions. This capability confers AgNPs with potent antibacterial and antifungal properties. Leveraging these properties, AgNPs are poised to play a crucial role in mitigating wound inflammation and enhancing wound healing when applied topically. At Arcana Nano, we offer an extensive assortment of silver nanoparticles, varying in size, shape, and surface chemistry to cater to a broad spectrum of applications.

Utilizations of Silver Nanoparticles
Healthcare Implementations
Silver nanoparticles are extensively integrated into wound care products, serving as potent antiseptics and disinfectants in medical settings and everyday consumer items. Due to their high surface area-to-mass ratio, these nanoparticles steadily release silver ions into their surroundings. These ions exhibit broad-spectrum antimicrobial activity against diverse bacteria. Through precise control over nanoparticle attributes such as size, shape, surface properties, and aggregation state, tailored silver ion release profiles can be engineered to suit specific application requirements.
Electrically Conductive Blends
The integration of silver particles into plastics, composites, and adhesives enhances the electrical conductivity of the material. Silver pastes and epoxies find extensive use in various electronics applications. Inks based on silver nanoparticles are employed for printing flexible electronics, offering the advantage of significantly lower melting points compared to bulk silver. Upon sintering, these inks exhibit exceptional conductivity.
Plasmonic Phenomena
Silver nanoparticles exhibit unique optical characteristics due to their ability to support surface plasmons. At specific wavelengths of light, these surface plasmons resonate strongly, resulting in significant absorption or scattering of incident light. This phenomenon is robust enough to enable the imaging of individual nanoparticles as small as 20 nm in diameter using conventional dark field microscopy. The profound interaction of metal nanostructures with light forms the cornerstone of the emerging field of plasmonics. Applications of plasmonic silver nanoparticles encompass biomedical labeling, sensing, and detection. Additionally, they underpin advanced analysis techniques such as Surface Enhanced Raman Spectroscopy (SERS) and Surface Enhanced Fluorescent Spectroscopy.
Solar Energy Conversion
There’s a growing fascination with harnessing the substantial scattering and absorption capabilities of plasmonic silver nanoparticles for solar energy applications. By serving as effective optical antennas, these nanoparticles enable the achievement of remarkably high efficiencies when integrated into solar collectors.

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.
