COVID-19

Abstract Objective: Many severe acute respiratory infections are caused by viral pathogens, and viruses are responsible for a large number of deaths worldwide. Among the most common respiratory viruses are the influenza A virus (IAV) and, more recently, the SARS-CoV-2 that emerged in 2019 and…

Background The lipid self-emulsifying system has been advanced as a promising delivery vehicle for improving the solubility and bioavailability of artemether and lumefantrine. However, the observed kinetic instability (propensity of lumefantrine to rapid crystallisation from nano-scale droplets) in…

A library of 16 lipid nanoparticle (LNP) formulations with orthogonally varying lipid molar ratios was designed and synthesized, using polyadenylic acid  as a model for mRNA, to explore the effect of lipid composition in LNPs on (i) the initial size of the resultant LNPs and encapsulation efficiency…
