Application:

Nanoparticle Size Analysis: Measures particle size distribution and zeta potential of nanoparticles to ensure stability and efficacy.
DLS helps monitor protein aggregation, which is essential for drug development, biopharmaceutical manufacturing, and quality control.
DLS is widely used to characterize colloids and emulsions, which are common in paints, pigments, food products, and cosmetics.
Measures molecular weight, size, and aggregation behavior of proteins and polymers in biotechnology and biomedical research.
Assesses nanoparticles in water samples, helping detect contaminants or pollutants and study colloidal behavior in environmental systems.
Assess the polydispersity index of the colloidal suspensions, which is important for all biological or biomedical applications.
