Sub-Diffraction Limit Imaging of Inorganic Nanowire Networks Interfacing Cells




Sub-diffraction limit imaging of SnO2 nanowires (NWs) interfacing cells is studied using stochastic optical reconstruction microscopy. This method allows the estimation of the dimension of the NWs with a rather high resolution compared with previous imaging methods. In addition, since this strategy is compatible with biological environments, the NWs can be imaged with cell membrane proteins simultaneously and the effect of the NWs on the cell adhesion efficiency can be analyzed.
