“…DLS is widely used for research in food science, and it plays an essential role in the characterization and evaluation of colloids, emulsions, and suspensions. Rao et al [ 110 ] described DLS as a faster and easier technique with lower limit detection to measure particle size than other techniques. One of the advantages of DLS is that sample preparation is minimal and noninvasive.…”

Colloidal systems and their control play an essential role in daily human activities, but several drawbacks lead to an avoidance of their extensive application in some more productive areas. Some roadblocks are a lack of knowledge regarding how to influence and address colloidal forces, as well as a lack of practical devices to understand these systems. This review focuses on applying dynamic light scattering (DLS) as a powerful tool for monitoring and characterizing nanoparticle aggregation dynamics. We started by outlining the core ideas behind DLS and how it may be used to examine colloidal particle size distribution and aggregation dynamics; then, in the last section, we included the options to control aggregation in the chemically processed toner. In addition, we pinpointed knowledge gaps and difficulties that obstruct the use of DLS in real-world situations. Although widely used, DLS has limits when dealing with complicated systems, including combinations of nanoparticles, high concentrations, and non-spherical particles. We discussed these issues and offered possible solutions and the incorporation of supplementary characterization approaches. Finally, we emphasized how critical it is to close the gap between fundamental studies of nanoparticle aggregation and their translation into real-world applications, recognizing challenges in colloidal science.

“…Dynamic light scattering (DLS) is a non-destructive spectroscopic technique widely used for determining the size distribution of suspended colloids in dispersions or solutions. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] Typical applications for this method include measuring the size distributions of proteins, micelles, polymers, and nanoparticles. [4][5][6][7][8][9][10][11][12][13] In practice, a laser beam is directed towards a sample solution/dispersion, and the intensity of the scattered light is measured by a photon detector set at a fixed angle from the path of the laser and a fixed distance from the scattering sample.…”
