報(bào)告摘要：
Our primary research aim is to create new materials using a combination of principles, many of which are inspired by biology. The combination of unique molecular scaffolds and guanidinium-rich side chains has produced an array of polymers with robust transduction (and delivery) activity. Being a new area, the fundamental interactions between these new scaffolds and the plasma membrane are just beginning to be understood. The synthetic approach easily allows doubling the density of guanidine functional groups, which increases the transduction efficiency of the sequences. Cellular uptake studies on three different cell lines (HEK 293T, CHO, and Jurkat T cells) confirm that these synthetic analogs are highly efficient novel protein transduction domain mimics (PTDMs), that are more effective than TAT49-57 and nonaarginine (R9) and also highlights the usefulness of polymer chemistry at the chemistry- biology interface. It has become clear that the combination of molecular design, biophysical models, and biological evaluation provide a robust approach to novel proteinomimetics. Inspired by elastomeric proteins, we have built highly resilient networks. This was expanded to provide a robust platform for networks with wide bicontinuous compositional windows. Installing metal cations generated anion exchange membranes (AEMs).
