General overview of lipid-polymer hybrid nanoparticles, dendrimers, micelles, liposomes, spongosomes and cubosomes.

INTRODUCTION: In recent years, the wider use of nanotechnology has attracted greater attention from scientists in multi-disciplinary fields. Nanotechnological research has come a long way in the past decade, with major advances being made, both in terms of diagnostic and therapeutic potential of nanoparticles. Areas covered: Some of the prominently discussed nanoparticles in this day and age are polymeric micelles, liposomes, lipid-polymer hybrid nanoparticles, dendrimers, spongosomes and cubosomes. This review attempts to focus on the conventional advantages and exemplary features that these particles possess, thus making them some of the most ideal vehicles for drug delivery. Expert opinion: Particulate systems, which have been extensively studied in this article, have been employed to enhance the pharmacokinetic and pharmacodynamic characteristics of various hydrophobic and hydrophilic drug moieties, thus attempting to prolong the blood circulation times and increase their efficacy over unmodified drug molecules. These modification techniques have enabled these drug molecules to be delivered to the pharmacological sites of action at an optimised controlled rate, thus trying to minimise the potential for any toxicity resulting from the non-specific distribution of drug to various organs.
