  Subwavelength imaging by microsphere lenses is a promising label-free
super-resolution imaging technique. There is a growing interest to use live
cells to replace the widely used non-biological microsphere lenses. In this
work, we demonstrate the use of yeast cells for such imaging purpose. Using
fiber-based optical trapping technique, we successfully trapped a chain of
yeast cells and bring them to the vicinity of imaging objects. These yeast
cells work as near-field magnifying lenses and simultaneously pick up the
sub-diffraction information of the nanoscale objects under each cell and
project them into the far-field. Blu-ray disc of 100 nm feature can be clearly
resolved in a parallel manner by each cell, thus effectively increasing the
imaging field of view and imaging efficiency. Our work will contribute to the
further development of more advanced bio-superlens imaging system
