Single‐nanoparticle detection and sizing is demonstrated using a nanofiber pair in an aqueous environment. The sizing of nanoparticles with a single radius (100 nm) and of mixed nanoparticles with different radii (100 nm and 170 nm) are both realized, and the experimental results agree well with predictions of Rayleigh–Gans scattering, by taking the inhomogeneous field distribution of the nanofibers into account.
