biological research requires dynamic and wide-field optical microscopy with resolution down to nanometer to study the biological process in a sub-cell or single molecular level. to address this issue, we propose a dynamic wide-field optical nanoimaging method based on a meta-nanocavity platform (mncp) model which can be incorporated in micro/nano-fluidic systems so that the samples to be observed can be confined in a nano-scale space for the ease of imaging. it is found that this platform can support standing wave surface plasmons (sw-sps) interference pattern with a period of 105 nm for a 532 nm incident wavelength. furthermore, the potential application of the ncp for wide-field super-resolution imaging was discussed and the simulation results show that an imaging resolution of sub-80 nm can be achieved.
