2-arm-PEG-OligocationsTransiently Shield theLiver Sinusoids to Mitigate Off-Target Hepatic Expression of mRNALipid Nanoparticles

ABSTRACT Ionizable lipid nanoparticles (iLNPs) are powerful platforms for mRNA-based vaccines and immunotherapies; however, their intrinsic liver tropism compromises both safety and efficacy. Off-target hepatic protein expression from delivered mRNA raises safety concerns, and he...

A Programmable Nanovesicle Platform for MegapascalPressure Sensing

Abstract Hydrostatic pressure (HP) is a subtle yet pervasive force that shapes chemistry and biology from the ocean floor to living cells─yet real-time HP sensing at the microscale remains elusive. Here, we report pyrene-modified polyionic complex vesicles (Pyr-PICsomes) as a cla...
