NanoBrand provides Nanoparticle Customization Services to transform our bare (citrate‑coated) gold and silver nanoparticles into application‑ready materials with precisely engineered surface properties. By modifying the nanoparticle surface, we can apply a wide range of coatings, including organic molecules, polymers, biomolecules (such as antibodies, peptides, or nucleic acids), and inorganic or metallic layers, either as single shells or multi‑layer architectures tailored to specific functions. Coatings can be designed for defined end uses such as drug delivery, antimicrobial activity, SERS or imaging contrast, enhanced catalytic performance, or protective and stabilizing layers for challenging buffers and biological media.

Through careful surface chemistry design, we can impart a chosen surface charge (anionic, cationic, or neutral), tune hydrophobicity vs hydrophilicity, and improve biocompatibility, all of which govern how nanoparticles interact with cells, proteins, and other materials. Functional groups, targeting ligands, and reporter molecules can be conjugated to the nanoparticle surface to enable targeted delivery, biosensing, signal readout, or improved long‑term stability. By jointly tailoring both nanoparticle morphology (size and shape) and surface coatings, our customization service helps you maximize performance, safety, and specificity for advanced life‑science, diagnostic, and nanotechnology applications.
