| Research Abstract |
When a colloidal solution consisting of nano-sized acicular materials and bacterial cells is stimulated with sliding friction, at the interface of the hydrogel, the nano-sized acicular material and bacterial cells form a chestnut-bur shaped complex. When the sliding friction force becomes a driving force, the chestnut-bur shaped complex grows and penetrates the bacteria to form a penetration-intermediate. This phenomenon, with the formation of a penetration-intermediate, is known as the "Yoshida effect". This research demonstrated the Yoshida effect was utilized for quantitative detection method of asbestos and the occurrence of the Yoshida effect may be a driven force for prokaryote evolution during providing seismic stimulation.
