Abstract
We synthesized silica nano powder using ICP plasma and evaluated its adsorption ability for biotic substances such as proteins and molecular histamine. The silica particles with negative electric charge adsorbed cytochrome C and histamine which have a positive electric charge. On the other hand, OVA which has a negative electric charge was not adsorbed. We considered that electrostatic interactions dominate the adsorption process between silica particles and biotic substances.
