Lipid nanoparticles (LNPs) are a form of drug delivery vehicle, notable for their use in COVID-19 vaccines. LNPs encapsulate and protect nucleic acids (NA) and enable their delivery to cells. Currently, interactions within the core of LNPs are poorly understood, particularly between NA, water, and lipids, which are integral to the long-term stability and release efficiency of LNP formulations. This work analyzes physical properties of LNPs before and after stress treatments, and how LNP composition modifies the response to these stresses. This work suggests that the presence of NA alters the internal structure of LNPs, and that some physicochemical properties of lipids present in LNP formulations, as well as the conditions of the buffer surrounding the LNP, can impact NA release.
