Linear coupling of alignment with transport in a polymer electrolyte membrane.

Polymer electrolyte membranes (PEMs) selectively transport ions and polar molecules in a robust yet formable solid support. Tailored PEMs allow for devices such as solid-state batteries,'artificial muscle' actuators and reverse-osmosis water purifiers. Understanding how PEM structure and morphology relate to mobile species transport presents a challenge for designing next-generation materials.

Poly(glycoamidoamine) vehicles promote pDNA uptake through multiple routes and efficient gene expression via caveolae-mediated endocytosis.

The use of synthetic polymers for the delivery of nucleic acids holds considerable promise for understanding and treating disease at the molecular level. This work aims to decipher the cellular internalization mechanisms for a series of synthetic glycopolymer DNA delivery vehicles we have termed poly(glycoamidoamine)s (PGAAs). To this end, we have performed cellular delivery experiments in the presence of pharmacological endocytosis inhibitors.
