Lipid nanoparticles (LNPs) are microscopic structures composed of lipids, which are fatty molecules. They are typically spherical and range in size from tens to hundreds of nanometers. LNPs have garnered significant attention in recent years, particularly for their role as delivery vehicles in the pharmaceutical and biotechnology industries.

The primary function of LNPs is to encapsulate and protect therapeutic molecules, such as nucleic acids (like mRNA or siRNA) or small molecule drugs, and facilitate their delivery into target cells. The lipid components of LNPs can be carefully selected to influence their stability, biodegradability, and ability to interact with cell membranes. This controlled release mechanism is crucial for effective drug delivery and minimizing off-target effects.

The development of LNPs has been a key factor in the advancement of nucleic acid-based therapies. Their ability to shield fragile mRNA from degradation in the bloodstream and efficiently deliver it into cells has been instrumental in the success of certain vaccines. Beyond vaccines, researchers are exploring LNPs for a wide range of therapeutic applications, including gene therapy, cancer treatment, and the delivery of various other bioactive molecules. The precise formulation of LNPs can be tailored to optimize delivery to specific tissues or cell types, further enhancing their therapeutic potential.
