ChEMS Seminar: Abiotic Synthetic Polymers -- Functional Alternatives to Antibodies, and Applications for Protein Stabilization, Inhibition of Signal Transduction and as Broad-Spectrum Antivenom
Departments of Chemistry and Chemical Engineering & Materials Science
University of California, Irvine
Abstract: Advances in polymer synthesis, structural biology and nanotechnology have progressed to the point where we can design synthetic polymer nanoparticles (NPs) with antibody-like affinity and selectivity for targeted biomacromolecules.
The talk will describe abiotic protein/peptide affinity agents (“plastic antibodies”).
These agents, synthetic polymer NP hydrogels, are formulated with functional groups complementary to the biomacromolecule target. Unique to these materials is that their biomacromolecule affinity can be switched on/off by external stimuli including temperature, pH and ionic strength. The talk will be concerned with exploring the applications of these materials for protein separation and as potential therapeutic agents to replace antibody drugs.
