The following data repository contains raw data produced for the development of a passive nanorheological tool, where gold nanoparticles were used as nanoprobes to characterise localised dynamic rheology at the micro/nanoscale of the different investigated hydrogels through the experimental values of diffusion coefficient.
This data is presented in the form of videos, of 100 nm gold nanoparticles (nanoprobes) in different media (simple fluids and hydrogels), recorded using an optical inverted microscopy. Also, bulk rheological characterisation of the investigate media is presented in excel files.
