Light-triggered switching of liposome surface charge directs delivery of membrane impermeable payloads in vivo

Abstract: Surface charge plays a fundamental role in determining the fate of a nanoparticle, and any encapsulated contents, in vivo. Herein, we describe, and visualise in real time, light-triggered switching of liposome surface charge, from neutral to cationic, in situ and in vivo (embryonic zebrafish). Prior to light activation, intravenously administered liposomes, composed of just two lipid reagents, freely circulate and successfully evade innate immune cells present in the fish. Upon in situ irradiation and surface … Show more

“…In particular, the nanoscale size of nanoparticles (NPs) enhances cellular uptake and can optimize intracellular pathways due to their intrinsic physicochemical properties, and can therefore increase drug delivery to target tissues. 47 , 48 However, the inherent targeting ability resulting from the physicochemical properties of NPs is not enough to target specific tissues or damaged tissues, and additional studies on additional ligands that can bind to surface receptors on target cells or tissues have been performed to improve the targeting ability of NPs. 49 Likewise, nanoencapsulation with cell membranes with targeting molecules and encapsulation of the core NPs with cell membranes confer the targeting ability of the source cell to the NPs.…”

“…It needs to be emphasized here that the correlation of in vivo behaviors in zebrafish and mice is qualitative. [12,38] First, the differences in blood components, temperature, scale, flow rate, and shearing force in these two models resulted in much faster disassembly kinetics and elimination of polymeric NCs in the mouse model than zebrafish model. However, the disassembly rate, circulation time, and elimination rate of these three polymeric NCs in the zebrafish model had the same tendency as the mouse model.…”

“…Figure S2A), electrostatic repulsion may contribute to the barrier function of HA and possibly also of other glycocalyx components. 24 The charge of the glycocalyx at the interface with the surrounding fluid, where the Stern counterion layer is generated, is the most relevant for target particle engagement. We therefore measured the zeta potential (i.e., the potential difference between the dispersion medium and the Stern layer of both cells and their targets) using electrophoretic light scattering.…”
