Gold Nanoparticles - Non-Functionalized, Functionalized, Antibody Conjugates, DNA Mediated, and more.

Gold nanoparticles have many applications in biology and medicine due to their unique optical and physical properties. These versatile reagents can be used for biosensor development, as cellular probes, as drug delivery vehicles, or as optical contrast agents among others.

Cytodiagnostics spherical and non-spherical gold nanoparticle products are made with proprietary protocols resulting in particles with uniform shapes and narrow size distributions.
