Current treatments for retinal and choroidal neovascular diseases suffer from insufficient durability, including anti-vascular endothelial growth factor-A (VEGF-A) agents. It is, therefore, of interest to explore alternative methods that could allow for robust improvement in visual acuity with fewer injections required. Amongst various pre-clinical and clinical studies in the literature, a promising approach is the use of suprachoroidal injection with viral and non-viral gene delivery vectors.

pH-sensitive lipids are important components of lipid nanoparticles, which enable the targeted delivery and controlled release of drugs. Understanding the mechanism of pH-triggered drug release at the molecular level is important for the rational design of ionizable lipids. Based on a recently reported pH-switchable lipid, named SL2, molecular dynamics (MD) simulations were employed to explore the microscopic mechanism behind the membrane destabilization induced by the conformational change of pH-switchable lipids.

The main issues with current and traditional cancer therapy delivery systems include a lack of selectivity towards tumors, causing harm to healthy cells, low efficiency in loading drugs, and the inability to visually track the drug's localization after administration. These limitations negatively impact the effectiveness of therapy and result in increased treatment costs. Furthermore, conventional cancer therapies typically target tumor cells through a single mechanism, which eventually leads to the emergence of drug resistance.

Small extracellular vesicles (sEVs) are promising nanocarriers for drug delivery to treat a wide range of diseases due to their natural origin and innate homing properties. However, suboptimal therapeutic effects, attributed to ineffective targeting, limited lysosomal escape, and insufficient delivery, remain challenges in effectively delivering therapeutic cargo. Despite advances in sEV-based drug delivery systems, conventional approaches need improvement to address low drug-loading efficiency and to develop surface functionalization techniques for precise targeting of cells of interest, all while preserving the membrane integrity of sEVs.

Over the last two decades, lipid nanoparticles (LNPs) have evolved as an effective biocompatible and biodegradable RNA delivery platform in the fields of nanomedicine, biotechnology, and drug delivery. They are novel bionanomaterials that can be used to encapsulate a wide range of biomolecules, such as mRNA, as demonstrated by the current successes of COVID-19 mRNA vaccines. Therefore, it is important to provide a perspective on LNPs for RNA delivery, which further offers useful guidance for researchers who want to work in the RNA-based LNP field.
