Development of GTP-responsive liposomes by exchanging the metal-DPA binding site in a synthetic lipid switch

Abstract

We report stimuli-responsive liposomes that selectively release encapsulated contents upon treatment with guanosine triphosphate (GTP) over a wide variety of phosphorylated metabolites, validated by fluorescence-based leakage assays. Significant changes in liposome self-assembly properties were also observed. Our results showcase the potential of this platform for triggered release applications.
