The team of Dr. Elisha Krieg at the Leibniz Institute of Polymer Research Dresden has developed a dynamic DNA-crosslinked matrix (DyNAtrix) by combining classical synthetic polymers with programmable DNA crosslinkers. DNA’s highly specific and predictable binding gives researchers unparalleled control over key mechanical properties of the material. The findings published in Nature Nanotechnology August 7, 2023, are highly relevant to in vitro cell culture materials for biological research.
