Solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC) for the delivery of bioactives sourced from plants: part I - composition and production methods.

INTRODUCTION

Nanoparticles (NPs) are widely used in the pharmaceutical field to treat various human disorders. Among these, lipid-based NPs (LNPs), including solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC), are favored for drug/bioactive delivery due to their high stability, biocompatibility, encapsulation efficiency, and sustained/controlled release. These properties make them particularly suitable as carriers of compounds derived from plant sources.

AREAS COVERED

This study comprehensively explores updated literature knowledge on SLN and NLC, focusing on their composition and production methods for the specific delivery of drug/bioactive compounds derived from plant sources of interest in pharmaceutical and biomedical fields.

EXPERT OPINION

SLN and NLC facilitate the development of more effective natural product-based therapies, aiming to reduce dosage and minimize side effects. These delivery systems align with the consumer demands for safer and more sustainable products, as there are also based on biocompatible and biodegradable raw materials, thereby posing minimal toxicological risks while also meeting regulatory guidelines.
