Functionalized Gold Nanoparticles

Gold nanoparticles can be used to target cells for imaging and photothermal therapy, drug delivery, biomarkers, immunoassays and more.

Take advantage of the unique optical and biocompatible properties of gold nanoparticles and nanostructures with our easy-to-use kits. We offer maleimide and N-hydroxysuccinimide (NHS) functionalized kits for one-step conjugation of antibodies, DNA/RNA, peptides and proteins. Kits contain lyophilized nanoparticles and ready-to-use mixtures.
