title: An acoustic based, laser induced breakdown method for determining the sizes and concentrations of nanoparticles.
abstract: An acoustic, laser induced breakdown (LIBD) method has been developed for determining the sizes and concentrations of nano-sized colloids. The size distributions from a mixture of aquatic nanoparticles are determined by measuring amplitudes of plasma shockwave that are fitted to multi-curve Gaussian distributions displayed in separate peaks with positions corresponding to particle sizes and areas being proportional to concentrations.
