Capillary-Based Physicochemical Characterization of Lipid Nanoparticles. [PDF]

Electrophoresis
ABSTRACT Lipid nanoparticles (LNPs) are widely used for the delivery of nucleic acid (NAs), most notably in gene therapy and messenger ribonucleic acid (mRNA)‐based vaccines. Understanding their physicochemical properties is essential, yet current analytical approaches often fall short in capturing their complexity.

Recent Developments in Deep Eutectic Solvents Applications in Liquid Chromatography: 2019-2025. [PDF]

J Sep Sci
ABSTRACT Deep eutectic solvents (DES) are used as mobile phase and stationary phase modifiers, or as for the stationary phase itself for thin layer/liquid/supercritical chromatography. Their specific properties can improve the separation selectivity, reduce peak tailing, and shorten the separation time.
