2.4. Dynamic Light Scattering (DLS)

DLS is a proven non-invasive technique, which can be used to determine the size distribution of small particles in suspension or in solutions of polymers. It can be used to investigate effectively particles of less than 1 nm diameter. The measurements of the size of silver nanoparticles in pre-incubated dispersion were performed at a temperature of 25 °C. The size of nanoparticles, as well as their volume distribution profiles were analysed. The DLS technique and measurement procedure have been described in previous works [19]. The size and volume distribution of silver nanoparticles were determined with the dynamic light scattering technique (DLS) with a PSS Nicomp 380 particle sizer (PSS NIKOMP, Santa Barbara, CA, USA) system. The DLS analysis of the size of silver nanoparticles was done based on Nikomp Distribution with PS Nikomp software’s CW 388 application (v. 1.55).
