WebDynamic light scattering (DLS) provides a measure of the size of the particles from the scattered light in a solution. DLS can detect the change in conformation of the DNA due to intercalation because of the change in the size distribution caused by it (Chirico, Lunelli, & Baldini, 1990; Newman, 1984). WebThe size distribution of CaP particles was determined by means of dynamic light scattering using a photon correlation spectrophotometer equipped with a 532 nm “green” laser (Zetasizer Nano ZS, Malvern Instruments, Worcestershire, UK). The intensity of scattered light was detected at the angle of 173°.

WebOct 6, 2016 · Dynamic light scattering (DLS), also known as photon correlation spectroscopy (PCS), is a very powerful tool for studying the diffusion behaviour of macromolecules in solution.
