Nanotechnology, a transformative force, has steadily gained traction across multiple scientific disciplines, including physics, chemistry, engineering, and biology. It offers unprecedented capabilities, especially in the realm of nanoscale particles, ushering in new paradigms in various applications. One of the most revolutionary applications of nanotechnology is in the pharmaceutical sector. Here, nanoparticles have transformed drug and vaccine delivery systems, offering both efficacy and precision. Among these nanoparticles, lipid nanoparticles (LNPs) have stood out, especially for their role in delivering nucleic acid-based drugs and vaccines. These LNPs are intricate assemblies composed of lipids and nucleic acid complexes, offering an amalgamation of stability and deliverability. Such properties have rendered LNPs as invaluable tools in enhancing therapeutic efficacy while minimizing off-target side effects. The myriad of nanoparticles available includes the likes of silver, gold, and lipid nanoparticles. However, the emphasis of this research lies with lipid nanoparticles, given their widespread success in the pharmaceutical arena. LNPs have showcased their potential in delivering drugs with low therapeutic indices, emphasizing their capability to act as versatile platforms for novel drug development. Recent advances have further expanded the horizons of LNPs, paving the way for novel antisense oligonucleotides, innovative vaccines, and complex lipid nanoparticle formations. Characterizing these nanoparticles is paramount, not only for the development of novel drugs but also to comprehend their in vivo behavior. Their multifaceted nature, stemming from their unique excipients, core-bilayer design, and varying sizes, makes their characterization a critical step in the research and development pipeline.
