    Enhanced Assay SensitivityScalable Bulk ProductionExpert Technical Support

    We specialize in providing biotinylated gold nanoparticles (AuNPs) that combine precise nanotechnology with advanced bioconjugation chemistry to deliver superior performance in biomedical research, diagnostics, and biosensing. By functionalizing gold nanoparticles with biotin through stable PEG-thiol linkers, we enable strong, highly specific biotin–streptavidin interactions while minimizing nonspecific binding. Our offering covers both standardized catalog products for fast deployment and fully customized solutions designed to match your exact requirements in size, optical properties, surface chemistry, and buffer compatibility. Whether you are developing a lateral flow assay, working on targeted imaging, or scaling up to commercial diagnostic kits, we ensure every batch meets stringent quality standards and reproducibility benchmarks.

    Problems We Solve

    Unreliable binding in assays

    Our biotinylated AuNPs guarantee robust biotin-streptavidin interactions, eliminating variability in ELISA, lateral flow assays (LFA), and biosensor platforms.

    Non-specific adsorption issues

    With PEGylated surface chemistry, our nanoparticles reduce background noise and improve assay sensitivity.

    Limited customization

    Many labs struggle to find particles in the right size, concentration, or surface density. We provide flexible solutions to match your exact experimental design.

    Scale-up challenges

    For teams moving from R&D to commercialization, we ensure reproducibility, batch consistency, and scalable manufacturing that complies with industry standards.
