FEP tubing (1.9 mm outer diameter and 1.1 mm inner diameter) with M6 screw connectors were attached to the inlet and outlet of the flow cuvette. Two holes were made on the lid of the cuvette holder in DLS instrument, facilitating the two tubing to pass through, while also ensuring that the cuvette environment was well protected from any penetration of light. Furthermore, a lid holder was 3D printed and placed over the lid for better secured and enforced fitting of the lid over the cuvette environment. Inlet tubing carried nanoparticles coming after mixing in micro mixer. The outlet tubing coming out of the cuvette was passed into a waste container. The schematic diagram of the experimental setup for this platform is shown below in Figure . The actual experimental setup is shown in Figure . Table gives the description of flow parts used in the experimental setup.
