Computational Design of Oligopeptide Containing Poly(ethylene glycol) Brushes for Stimuli-Responsive Drug Delivery.

ABSTRACT: Stimuli-responsive biomaterials are used to facilitate drug and gene delivery by shielding the drug/gene during circulation times and selectively releasing the cargo at the desired target. Within stimuli-responsive materials, pH-responsive materials are exploited for delivery to specific organs, intracellular compartments, cancer cells, site of inflammation or infection as those sites are characterized by pH that is different from the blood pH. In this paper we use molecular dynamics (MD) simulations to design such pH-responsive biomaterials where the balance between the various intermolecular interactions (e.g., electrostatics, van der Waals) within the biomaterials allow biofunctional molecules to be reversibly shielded and exposed to the environment with change in pH. In our model the s
