This breakthrough was made possible through decades of research into RNA biology and delivery systems. The journey began in the 1990s with the first successful in vitro transcription of mRNA, followed by crucial discoveries addressing stability issues and immune response challenges in the early 2000s.

Lipid nanoparticles (LNPs) emerged as the gold standard for mRNA delivery around 2010, offering protection from enzymatic degradation and facilitating cellular uptake. The technology has since evolved from simple liposomal formulations to sophisticated multi-component systems incorporating ionizable lipids, helper phospholipids, cholesterol, and PEG-lipids, each serving specific functions in the delivery process.

Electrode dynamics represent a critical yet underexplored aspect of mRNA LNP production and delivery. The electrokinetic properties at the interface between delivery systems and biological membranes significantly impact transfection efficiency. Traditional methods for LNP production, such as thin-film hydration and ethanol injection, have been increasingly replaced by microfluidic and electroformation techniques that offer better control over particle size distribution and loading capacity.

The electrode-based manufacturing processes introduce unique challenges related to surface charge distribution, electrochemical stability, and the formation of electrical double layers that influence LNP characteristics. Understanding these dynamics is essential for optimizing delivery efficiency and reducing variability in therapeutic outcomes. Recent advances in electrode materials and configurations have shown promise in enhancing reproducibility and scalability of LNP production.

Our technical objectives focus on comprehensively analyzing electrode dynamics in mRNA LNP delivery systems to develop next-generation manufacturing processes. Specifically, we aim to characterize the electrochemical interactions between different electrode materials and lipid components, quantify the impact of electrical parameters on LNP size distribution and morphology, and develop predictive models correlating electrode properties with transfection efficiency.

Additionally, we seek to investigate novel electrode configurations that could enable precise control over LNP surface charge and stability. This includes exploring pulsed electric field applications, microelectrode arrays, and biocompatible electrode materials that minimize contamination risks while maximizing production efficiency. The ultimate goal is to establish standardized electrode-based manufacturing protocols that ensure consistent, high-quality mRNA LNP production at commercial scale.

The findings from this research will address critical knowledge gaps in the field and potentially unlock new capabilities in mRNA therapeutics beyond vaccines, including protein replacement therapies, cancer immunotherapies, and genetic disorder treatments.
