Lipid Nanoparticle Overview

Application Note

Lipid nanoparticles (LNPs) stand as the most advanced non-viral gene delivery system within clinical practice. They have proven their capability to safely and efficiently transport nucleic acids, addressing a significant obstacle that previously hindered the progress and utilization of genetic medicines. Genetic medicine encompasses various applications, including gene editing, the expedited development of vaccines, immuno-oncology, and the treatment of rare genetic and previously untreatable diseases. All of these applications have traditionally faced challenges due to inefficiencies in nucleic acid delivery.

Lipid Nanoparticles (LNPs) are a class of nanoscale delivery systems designed to transport and protect therapeutic molecules, such as drugs and RNA, to specific target sites within the body. They have gained significant attention in the field of medicine and biotechnology due to their ability to enhance the bioavailability and efficacy of drugs by improving stability and ability to target points of interest for drug delivery. The basic structure of an LNP consists of a lipid bilayer surrounding a hydrophobic core. This structure allows the LNPs to encapsulate hydrophobic drugs or nucleic acids within the core while keeping the hydrophilic components on the surface, making them stable and compatible with the aqueous environment of the body.

LNP Formulation & Preparation Protocol

Conventionally, solvent injection and thin film rehydration are two common methods for liposome synthesis. Due to the simplicity of equipment requirements, such as sonicators or rotary evaporators, solvent injection and thin film rehydration methods are widely adopted in both research and production process. However, these traditional methods meet the challenges of low homogeneity of resulted LNPs, hash processes for delicate biomolecules, such as DNAs, RNAs or proteins. To address these challenges, microfluidic mixing method has been rapidly developed in the past decade.

Genetic drugs, including small interfering RNA (siRNA), mRNA, or plasmid DNA, hold promise for treating a wide array of diseases by either suppressing harmful genes, producing therapeutic proteins, or employing gene-editing techniques. Currently, lipid nanoparticle (LNP) systems stand at the forefront among non-viral delivery methods, enabling the clinical utilization of genetic drugs.


LNP for vaccine

Lipid nanoparticle has played a pivotal role in expediting the development of vaccines, as demonstrated by Pfizer and Moderna in the COVID-19 pandemic response. It allows for precise and high-throughput screening of potential vaccine candidates. The technology facilitates rapid testing, antigen formulation, and optimization of vaccine delivery systems.

Cell Therapy

Cell Therapies entail the transformation of cells, commonly immune cells, obtained either from the patient (autologous) or a compatible donor (allogeneic). These modified cells undergo isolation, amplification, and are later reintroduced into the patient. Lipid Nanoparticles (LNPs) present a versatile approach to cell reprogramming, facilitating the transfer of RNA responsible for protein expression or gene editing. 

Other Areas
