Determination of size and refractive index of single gold nanoparticles using an optofluidic chip

Determination of size and refractive index of single gold nanoparticles using an optofluidic chip

We report a real-time method to determine the size, i.e. diameter, and refractive index of single gold nanoparticles using an optofluidic chip, which consists of a quasi-Bessel beam optical chromatography. The tightly focused (∼ 0.5 μm) quasi-Bessel beam with low divergence (NA ∼ 0.04) was used to t...
