Biomimetic DNA Nanotechnology to Understand and Control Cellular Responses

At the cellular level, numerous nanocues guide the cells to adhere, interact, proliferate, differentiate, etc. Understanding and manipulating the cellular functions in vitro, necessitates the elucidation of these nanocues provided to the cells by the extracellular matrix (ECM), neighbouring cells or in the form of ligands. DNA nanotechnology is a biocompatible, flexible and a promising molecular level toolkit for mimicking cell-cell and cell-matrix interactions. In this review, we summarize various advances in cell-matrix, cell-cell and cell receptor-ligand interactions using DNA nanotechnology as a tool. We also provide a brief outlook on the current challenges and the future potentials of these DNA-based nanostructures so as to inspire novel innovations in the field.
