University of Nottingham May 23 2025 Scientists have developed a method for analyzing the structure of lipid nanoparticles that could be used to improve vaccine and drug delivery, targeting a wide range of health issues. A team led by scientists at the University of Nottingham's School of Pharmacy demonstrated a new cryogenic mass spectrometry approach for depth profiling frozen tiny lipid nanoparticles to reveal the layers and orientation of the constituent molecules. The findings have been
