Fluorescent Gold Nanoparticles

Fluorescent Gold Nanoparticles

Creative Diagnostics provides Fluorescent Gold Nanoparticles (AuNPs) labeled with various fluorophores for multimodal imaging by dark-field scattering, fluorescence, as well as electron microscopy. The fluorophore labeled gold nanoparticles exhibit both high absorptions and scattering from gold nanoparticle as well as enhanced fluorescence from the attached fluorophores. Gold nanoparticles significant enhance the fluorescent signal and quantum yield of fluorophores based on the metal-enhanced fluorescence (MEF) effect.

These nanoparticles are available with the following fluorophores, IRDye 800, Alexa Fluor 750, Alexa Fluor 680, Cy5.5, Alexa Fluor 647, Cy5, Alexa Fluor 633, Alexa Fluor 594, Texas Red, Alexa Fluor 546, Alexa Fluor 555, FITC, Alexa Fluor 488.

Various active groups or ligands can be chosen according to customer's need, including amine, biotin, carboxyl, maleimide, methyl, neutravidin, NHS, streptavidin, MUTAB, protein A and secondary antibodies. PEG or proprietary polymer is used as covalent polymer bridge to the most popular in vitro terminations. For in vivo surface terminations, a proprietary long circulating polymer would give the gold nanoparticles ultra-long circulation time.

The fluorophore labeled AuNPs are supplied in distilled water, PBS, Tris, Sodium Borate or MES; Other custom buffers are also available on request.

Creative Diagnostics also offers a series of fluorophore labeled AuNPs with specific cellular uptake ligands to promote cellular uptake. These gold nanoparticles are non-toxic, suited for in vivo application.

Custom conjugations are available for special fluorophores, functional surfaces and molecules, such as antibodies, proteins, peptides, lectins, etc.

Please do not hesitate to contact us if you need free consultation and a detailed quotation of your project. Our customer service representatives are available 24 hours a day, from Monday to Sunday.
