Self-assembly of gold nanoparticles measured with MP-SPR

Application Note #140

Langmuir-blodgett

Whole SPR curves during gold nanoparticle deposition, measured with 785nm wavelength.

 

Gold nanoparticles were immobilized on a monolayer selfassembled on gold. Functional groups on the chain ends of the monolayer facilitated an anchoring of gold nanoparticles to the layer. Multi-Parametric Surface Plasmon Resonance (MP-SPR) enabled a real-time measurement of the binding of the gold nanoparticles to the surface layer.
