Dynamic Light Scattering (DLS)

Analytical

Dynamic Light Scattering (DLS) — A technique that measures particle size distribution by analyzing fluctuations in scattered light intensity, used to detect peptide aggregation and nanoparticle size.

What Is Dynamic Light Scattering?

Dynamic light scattering (DLS) measures the size distribution of particles in solution by analyzing the time-dependent fluctuations in scattered laser light intensity. In peptide research, DLS detects aggregation, determines nanoparticle size, and monitors peptide self-assembly in real time without labels or sample destruction.

Applications

Aggregation screening: Detects soluble aggregates (oligomers) before they become visible precipitates
Nanoparticle sizing: Characterizes peptide-loaded PLGA, liposome, and self-assembling peptide nanoparticles (1 nm to 10 µm)
Formulation stability: Monitors particle size over time to detect incipient aggregation during shelf life studies
Thermal stability: Temperature-ramped DLS identifies aggregation onset temperature (Tagg)
