S&M3027 Research Paper of Special Issue https://doi.org/10.18494/SAM3751 Published in advance: April 4, 2022 Published: August 15, 2022 Analysis of Local Viscosity in Alginate Gel via Bead-based Diffusometry [PDF] Ayako Koto, Shota Nishimoto, Hiroaki Sakamoto, Han-Sheng Chuang, Hideyuki Uematsu, Shuichi Tanoue, Eiichiro Takamura, and Shin-ichiro Suye (Received November 27, 2021; Accepted February 24, 2022) Keywords: microscopic viscosity, diffusivity, microscope, fluorescent particles, alginate gel
In this study, we evaluated the microscopic viscosity of sol-gel films by observing the diffusion behavior (particle diffusivity) of fluorescent particles dispersed in colloids such as sols and gels. The dynamic viscosity was compared with the particle diffusivity for several alginate solutions of different concentrations, and it was found that the particle diffusivity and solution viscosity were correlated. Localized analysis of the inside of a gel thin film suggested that material phase changes can be evaluated by observing changes in particle diffusivity. Because the diffusion behavior of fluorescent particles was observed by microscopy, it was possible to obtain arbitrary local viscosity information from inside the material. Spatially and temporally continuous characterization of the inside of thin films made of polymeric materials can be performed by a very simple method.
