摘要
An impulsive force generated by focusing a femtosecond laser into water through an objective lens was directly measured utilizing an atomic force microscope (AFM). We analyzed the transient bending movement of the AFM cantilever initiated by the impulsive force and suggested a procedure to quantify it. The order was 10(-12) Ns, corresponding to the average force of mu N in mu s timescale. The quantification creates a new way of estimating intercellular adhesion strength, because it is possible to dissociate cell-cell adhesion by the impulsive force.
