MAGNETIC NANOLIPOSOMES: A REVIEW ON PREPARATION AND CHARACTERIZATION METHODS

Magnetic nanoliposomes are versatile nanocarriers for targeted drug delivery. These liposomes can enhance the efficacy of bioactive compounds by improving pharmacokinetic parameters. Chemical ingredients of magnetic nanoliposomes include ferrofluid, cholesterol and phospholipid molecules. The preparation of magnetic nanoliposomes involves two steps viz. synthesis of magnetic nanoparticles and then combination with prepared nanoliposomes. The magnetic nanoliposomes are synthesized by various chemical methods including co-precipitation, thermal decomposition, microemulsion and hydrothermal synthesis. The nanoliposomes are prepared by sonication, extrusion, micro-fluidization techniques. Characterization studies included size, nanoparticle tracking analysis, flow cytometry, size exclusion chromatography, DSC, encapsulation efficiency. This study provides an overview of the preparation and characterization techniques of magnetic nanoliposomes.

BIOAVAILABILITY ENHANCEMENT AND LIPID NANOCARRIER BASED DELIVERY OF PEPTIDES AND PROTEINS

Peptides and proteins are vital biomacromolecules that perform several bodily functions in various physiological and biological processes. Being biocompatible and biodegradable, these macromolecules are considered promising platforms for delivery of drugs and genes. However, peptides and proteins suffer from major limitations including enzymatic degradation, short circulation half-lives, and poor membrane permeability that leads to poor bioavailability, challenging their effective delivery. This article briefly discusses the inherent challenges in peptide and protein delivery along with strategies for bioavailability enhancement and lipid nanocarriers as prospective systems for peptide and protein drug delivery.
