In the hemostatic phenomenon induced by low-temperature atmospheric pressure plasma jet treatment, it has been reported that, in addition to activation of the coagulation system and hemolysis, aggregation of serum proteins occurs. This study focused on the protein aggregation phenomenon. Plasma irradiation experiments were conducted on serum protein (BSA) solutions under varying buffer conditions, using solutions with different pH levels and conductivities. The results showed that the volume of aggregates tended to increase with decreasing pH, differing from the simple colloidal aggregation behavior where aggregates reach maximum volume near the isoelectric point.
