In addition, the PEGylation of liposomes in Doxil ® supported prolonging the circulation time of this formula after administration.

Because of the encapsulation of doxorubicin inside PEGylated liposomes, the side effects of free doxorubicin, including chronic cardiomyopathy and congestive heart failure, were significantly mitigated. This milestone was reached by Doxil ®, a stealth liposome encapsulating doxorubicin ( Figure 1a) and used for the clinical treatment of ovarian and metastatic breast cancer as well as various forms of myeloma. Though liposomes have been explored for 30 years as an effective carrier for a variety of drug molecules, it was only in the 1990s that the first Food and Drug Administration (FDA) approval came. As a result, the overall efficacy of these liposomes is improved compared to conventional liposomes.

Later, in 1980, the first targeted liposomes, modified by active targeting ligands, were developed and led to significantly improve liposome capacity by increasing accumulation at the target tissues/organs/cells without releasing the drug to other sites. Liposomes were observed under the electron microscope when adding negative stain to dry phospholipids that assembled into spherical shape through a lipid bilayer.

The traditional type of lipid nanoparticles is liposomes which was first described in 1961 by the British haematologist, Alec D Bangham. Lipid nanoparticles are multicomponent lipid systems typically containing a phospholipid, an ionizable lipid, cholesterol, and a PEGylated lipid. More than 50 nanopharmaceuticals have made it to the market consisting of diverse nanoformulations, with lipid nanoparticles being the frontrunner. These formulations exhibit many advantages over free drug molecules, possessing an enhanced solubility and improved pharmacokinetics, efficacy, and minimal toxicity. Nanoformulation was defined by the Food and Drug Administration (FDA) that is the products in combination with nanoparticles ranging from 1–100 nanometers (nm) or other formulations outside of this range showing dimension-dependent properties. Nanomedicine is the convergence of nanotechnology, pharmaceutical, and biomedical sciences and has developed rapidly with the design of new nanoformulations for therapeutic purposes, imaging agents and theragnostic applications. This review serves as a useful guideline for designing new lipid nanoparticles for both preventative and therapeutic vaccines including immunotherapies. We also discuss the physicochemical properties required for specific applications, highlight the differences in requirements for the delivery of different cargos, and introduce current challenges that need further development. We particularly focus on the innovations that have obtained regulatory approval or that are in clinical trials. The lipid-based nanoparticles discussed in this review are liposomes, niosomes, transfersomes, solid lipid nanoparticles, and nanostructured lipid carriers. In this review, we aim to highlight the progress in the development of these lipid nanoparticles for various applications, ranging from cancer nanomedicines to COVID-19 vaccines.

Lipid-based nanoparticles have played a pivotal role in the successes of COVID-19 vaccines and many other nanomedicines, such as Doxil ® and Onpattro ®, and have therefore been considered as the frontrunner in nanoscale drug delivery systems. COVID-19 vaccines have been developed with unprecedented speed which would not have been possible without decades of fundamental research on delivery nanotechnology.
