Title :Microrheological measurement of microcrystalline cellulose solution using single particle tracking
Year of Publication :2017

Full Text :
The aim of the research was to develop micro rheological measurement system to determine the alpha apparent and the complex shear modulus of microcrystalline cellulose (MCC) solutions based on a single particle tracking technique (SPT) using video microscopy (VM). The temporal displacement of a micro particle, acted as a probe in MCC solution was recorded, trackedand analyzed using custom-made MATLAB program. Videos were recorded at 30 fps resulted in the output of radial frequency range from 0.4 rad/s to 10 rad/s. The results from the local measurement in MCC solutions were compared with the bulk measurement using rheometer. The measurements were dependent on the local position of the probe in the solution. The results from the developed SPT-based measurement system were comparable to the common measurement using rheometer.
