IRG2 is organized to carry out a broad exploration of the sequence-directed self-assembly of functional materials using Click Nucleic Acids (CNAs). CNAs are a new DNA analog system, invented by Center investigators, in which oligomer chains with DNA-style sequences of selected bases are synthesized using thiol-ene click chemistry.</span></p></div></div></div> Sun, 13 Mar 2016 22:50:40 +0000 ucolorado 5516 at https://mrsec.org Covalent Adaptable Networks (CAN) for Sustainable and Regulatable Functional Materials https://mrsec.org/research/covalent-adaptable-networks-can-sustainable-and-regulatable-functional-materials <div class="field field-name-body field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even" property="content:encoded"><p><span><img src="https://lh7-us.googleusercontent.com/vKx8pQY8aGOVqP4GJt_h1qlU0Oo9RpY_YSje9suTYrUVwUwOmqF67UORVeW5V8DBZlbScTJOM3omE9kWgU0IcAOBt9qBd5fWFCMxZCyTuY0REgR80C7mWhsQc34n-1PtSpihM84lNerX8OWoFiUzez0" /></span></p></div></div></div> Tue, 31 Oct 2023 21:16:36 +0000 umichigan 6854 at https://mrsec.org Directed Polymer-Based Assemblies https://mrsec.org/research/directed-polymer-based-assemblies Sun, 13 Mar 2016 22:50:40 +0000 umass 5531 at https://mrsec.org Dynamics of Novel Self-Assembling Protein-Polymer Hydrogels https://mrsec.org/research/dynamics-novel-self-assembling-protein-polymer-hydrogels <div class="field field-name-body field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even" property="content:encoded"><p>Hydrogels are extensively used in medical applications and they are an important class of biomaterials that are under significant study for regenerative medicine applications.
