動態光散射量測技術

動態光散射 (DLS) 可快速且非破壞地量測溶液中粒子的粒徑分佈，常用於生化、材料科學領域。此技術通過照射雷射溶液中布朗運動的粒子，分析瑞利散射光的擾動變化，並計算粒子的擴散係數，藉此得到粒子粒徑分佈。
Dynamic Light Scattering (DLS) is a rapid, non-destructive technique widely used in biochemistry and materials science to determine the particle size distribution in solution. In a typical DLS measurement, a laser impinges onto the solution with particles undergoing Brownian motion, producing intensity fluctuations of Rayleigh scattering. Analyzing the autocorrelation of the scattered light intensity yields the particle diffusion coefficient, from which the particle size distribution is determined.
