Nanotechnology is currently a field of endeavour that has reached a maturation phase beyond the initial hypotheses with an undercurrent challenge to optimise the safety, and scalability for production and clinical trials. Lipid-based nanoparticles (LNP), namely solid lipid nanoparticles (SLN) and nanostructured lipid (NLC), carriers are presently among the most attractive and fast-growing areas of research. SLN and NLC are safe, biocompatible nanotechnology-enabled platforms with ubiquitous applications. This review presents a modern vision that starts with a brief description of characteristics, preparation strategies, and composition ingredients, benefits, and limitations. Next, a discussion of applications and functionalization approaches for the delivery of therapeutics via different routes of delivery. Additionally, the review presents a concise perspective into limitations and future advances. A brief recap on the prospects of molecular dynamics simulations in better understanding NP bio-interface interactions is provided. Finally, the alliance between 3D printing and nanomaterials is presented here as well.
