1. Lamgmuir-Blodgett (LB ) films is a monomolecular layer or mulitimolecular layer thin film material of organic high polymer with orientation arrangement structure.

2. The cleaning-solution composition comprises: a water-soluble polymer including a monomolecular acid compound expressed in chemical formula 1 or a repeating unit expressed in chemical formula 3; and a solvent.

3. The present invention relates to a method for analyzing the activation sate of a signaling pathway in a cell or tissue separated from a subject through real time monomolecular protein-protein interaction analysis, and a method for selecting a personalized medicine or predicting a therapeutic reactivity to a medicine using the same.
