In this paper, novel cell-based biosensing system with a high resolution of two dimensional surface plasmon resonance (2D-SPR) imager is introduced. Response of a model nerve precursor cell (PC12) which was adhered on an Au chip to agonist stimulation was observed by the reflection intensity change in the individual cell regions with the 2D-SPR imager at real-time without any probe reagents. It was further demonstrated that the cell response in 2D-SPR imaging to agonist stimulation might be based on intracellular recruitment of signal transduction proteins such as PKC to cell membrane. These results suggested future wide applications of label-free cell-based biosensing with 2D-SPR imager, such as drug screening, cell state evaluation and so on.
