Abstract

In this paper, we propose the concept of a microrobot that resembles a cell, fabricated by integrating functional biomaterials that occur naturally within cells, most notably DNA and proteins. This strategy offers a promising avenue for constructing robotic devices on the micrometer scale. Furthermore, we present the distinctive molecular systems and cell-like microrobots we have engineered, which display unique functions that arise from the rational combination of components derived from DNA and proteins.
