Our aldehyde functionalized, fluorescent PMMA (Polymethylmethacrylate) based nanospheres are available in sizes between 100 nm to 500 nm. Aldehyde groups react immediately with the NH2-terminus or other suitable functional groups of the probe to form a (covalent) bond with the surface. Thus, no activation of the bead surface is necessary prior to binding of the probe. Latex beads with aldehyde surfaces are suitable for immobilization of biomolecules (proteins, antibodies, haptens, etc.).
Please note, that PolyAn also produces customized nanoparticles which incorporate fluorophores for other spectral ranges. All PMMA Nanobeads are available in sizes between 100-500 nm. Custom modifications with antibodies and other biomolecules are available upon request. Please do not hesitate to contact us to get some of our PMMA-Nanobeads!
