July 15th: upcoming webinar on DWS - High frequency microrheology of hyaluronan
Join us on July 15th for a live webinar!
Prof. Samiul Amin (Manhattan College) will be presenting new applications of DWS optical microrheology in cosmetic formulations. The microstructure of surfactant/biosurfactant systems and its characterization through high frequency rheology will be highlighted.
This webinar will feature a Q&A session, and your questions can be submitted at any time through the live chat.
The webinar recording is now available! Check the link here below!
Hyaluronan is a linear polysaccharide widely used in cell culture, medical devices, and pharmaceutical applications such as eye drops, viscoelastic devices, and drug delivery. In the semi-dilute regime, hyaluronan chains form hydrogen bonds, which control the stiffness of the polymer and in turn, the viscoelastic properties of the material under consideration.
A pioneering work of the Willenbacher group at the Karlsruhe Institute of Technology has uncovered the high frequency rheological behavior of hyaluronan using the DWS RheoLab.
In particular, the chain flexibility in the entangled regime, was determined from the modulus data. Read more in the original article!
