In recent years, researchers have been exploring the use of lipid nanoparticles (LNPs) as a delivery tool for drugs and vaccines. LNPs are small particles made of lipids, which are naturally occurring molecules found in the cell walls of organisms. They are attractive to researchers due to their ability to transport drugs and other molecules across biological barriers, such as the blood-brain barrier. However, there are several barriers that still need to be overcome before LNPs can be used effectively as a drug delivery system. In this article, we will explore some of the challenges associated with using LNPs for drug delivery, as well as potential solutions to these issues.
