| Summary: | 碩士 === 國立成功大學 === 材料科學及工程學系 === 102 === Our main goal on this project is to observe the dynamic extracellular polymeric substance (EPS) secretion process during Streptococcus mutans’ biofilm formation. By Peakforce quantitative nanomechanical property mapping mode (Peakforce QNM) of Atomic force microscopy we obtained the mechanical property data which changed with EPS secretion. From our result, we found that adhesion force and dissipation energy distribution is related to the amount of expolysaccharides accumulation, adhesion force has the highest value at the place with larger height difference and each EPS layer with certain adhesion range are accompanied by EPS formation and consumption.
