Abstract

Lyotropic nonlamellar liquid crystalline nanoparticles (NPs) (LCN), such as cubosomes and hexosomes, are useful tools for applications in drug delivery because of their unique structural properties. LCNs are highly versatile carriers that can be applied for use with topical, oral, and intravenous treatments. In recent years, significant research has focused on improving their preparation and characterization, including controlling drug release and enhancing the efficacy of loaded bioactive molecules. Nevertheless, the clinical translation of LCN-based carriers has been slow. In this review, we highlight recent advances and challenges in the development and application of LCN, providing examples of their topical, oral, and intravenous drug delivery applications, and discussing translational obstacles to LCN as a NP technology.
