文摘
- •
We demonstrate and characterize multiparticle-induced MS where the sizes of particles are in a log-normal distribution using microsphere resonators.
- •
We experimentally confirm that the total linewidth broadening is proportional to the number of adsorbed particles.
- •
The signal is immune to the angular positions of particles as well as the thermal fluctuations, which exhibits a more robust mechanism.
