From: Machine learning to determine optimal conditions for controlling the size of elastin-based particles

ELP/ELP-PEI800 and ELP/ELP-PEI10K systematically form nano-and micro-aggregates above LCST when the solution conditions of salt concentration, polymer concentration, and pH are carefully controlled. The PEI block provides the ability to crosslink the copolymers and to achieve particles that remain stable below LCST even after removal of the harsh (high salt or pH) conditions used to create them.
