Soft matter, such as polymers, liquid crystals, colloids, and biomolecules, are widely used in various fields. In addition, biosystems, in which soft matter cooperates with each other in nonequilibrium, enable living organisms to maintain their biological activities. This session will cover all topics of relevant research focusing on soft matter and biosystems, including physicochemical phenomena, such as phase transitions and self-propulsion, from the viewpoint of fundamentals and applications.

• General Symposia

Symposium 1 (Tue, September 17, AM)

"Biocolloid and Interface Science: Unravelling interactions between biomolecules/colloids and biomembranes"

Various molecular assemblies including exosomes and bile acid micelles are participating in maintaining functions of living bodies. On the other hand, lipid nanoparticles have played an important role for developing the COVID-19 vaccines. It is mandatory to understand interactions between biomolecules/biocolloids and biomembranes for maintaining functions of living bodies. In this symposium, we will focus on the membrane permeation of biomolecules/biocolloids involved in maintaining functions of living bodies and healing diseases, and discuss the role of colloid and interface science in maintenance of human health.
