Abstract
A method for determining a radius of elements suspended in a medium includes binding the elements to nanoparticles to form bound element-nanoparticle aggregates, superposing first and second Doppler-shifted optical waves having a variable frequency shift between them in the medium such that there is a gain in energy of the first optical wave with respect to the second optical wave, varying the frequency shift and measuring the gain while varying the frequency shift to determine the value of the frequency shift at which there is a peak in the gain, determining the radius of the bound element-nanoparticle aggregates based on the value of the frequency shift at which there is a peak in the gain, and determining the radius of the elements based on the radius of the bound element-nanoparticle aggregates.
