Sonoporation is applied to enhance the permeability of the cell to bioactive materials by employing the acoustic cavitation of microbubbles. This phenomena would be helpful in molecular biology, delivery of large molecules into the cells and gene therapy. Many methods have been applied to monitor the biological effects and trace of sonoporation on the cells such as scanning/transmission electron microscopy, confocal imaging and flow cytometry. Here, we monitored the effect of sonoporation on the cells using electrochemical method with an integrated three electrode system. Electrochemical responses of stimulated cells, compared to flow cytometry and electron microscopy results, presented different patterns of sonoporation in the cells detectable by cyclic voltammetry. In addition, confocal microscopy from actin stress fibers and young's modulus measured by AFM revealed the correlation of cell mechanics and amount of induced sonopores in the cells. This method could be applied as a new trend in cellular mechanochemical studies.
