Liposome-like nanostructures for drug delivery

Summary

This review compares five families of drug carriers inspired by conventional liposomes: polymer-stabilized liposomes, nanoparticle-stabilized liposomes, core-shell lipid-polymer hybrids, natural membrane-derived vesicles, and natural membrane-coated nanoparticles. The central question is how newer structures preserve useful lipid-membrane behavior while addressing limitations of standard liposomes through added mechanical stability, controlled release, synthetic cores, or biological surface functions. The authors discuss distinctive strengths and recent biomedical progress for each category, emphasizing designs reported to improve therapeutic efficacy. The principal contribution is a common framework for understanding platforms that sit between classical liposomes, synthetic nanoparticles, and cell-derived materials. This is significant because the five architectures offer different balances of cargo compatibility, structural control, biological interaction, and manufacturability, so they should not be treated as one interchangeable technology. However, the abstract describes a narrative review rather than a systematic or quantitative comparison. It provides no search strategy, evidence grading, head-to-head performance, clinical outcomes, or product-level safety data, and does not specify which platform is superior for a given drug. Stability, release, biodistribution, immunogenicity, source variability, scale-up, sterilization, and regulatory maturity likely differ substantially but are not resolved in the abstract.
