Giant liposomes as delivery system for ecophysiological studies in copepods [PDF]
Journal of Experimental Biology, 2006 SUMMARYGiant liposomes are proposed as a potential delivery system in marine copepods, the dominant constituent of the zooplankton. Liposomes were prepared in the same size range as the food ingested by copepods (mean diameter of about 7 μm). The encapsulation of a hydrophilic and high molecular mass fluorescent compound, fluorescein isothiocyanate ...

Dynamic Electrochemiluminescence Imaging of Single Giant Liposome Opening at Polarized Electrodes
Analytical Chemistry, 2022 In this work, the characterization of release events from liposomes has been addressed quantitatively by an electrochemiluminescence (ECL) imaging strategy. First, ECL reagents ([Ru(bpy)3]2+ and tripropylamine) were encapsulated in sealed giant asymmetrical liposomes (100 μm in diameter) made of DOPG/DOPC phospholipids. After sedimentation on an indium

Study of macroscopic and microscopic properties of liposomes produced using microfluidic methods [PDF]
, 2019 For the last decades, lipid vesicles or liposomes, vesicles formed by a bilayer of amphiphilic lipids, have been used as a toy model for studying the cell membrane and for applications in cosmetics and drug delivery.

Angewandte Chemie International Edition, EarlyView.Biomimetic liposome nanoreactors mimicking natural light‐harvesting complexes enable efficient photooxidation of NADH. Membrane‐anchored fluorescein transfers energy via FRET to membrane anchored eosin Y, oxidizing NADH. While symmetric membranes show little improvement, asymmetric chromophore distribution enhances photooxidation rates by up to 27 ...

A minimal biochemical route towards de novo formation of synthetic phospholipid membranes. [PDF]
, 2019 All living cells consist of membrane compartments, which are mainly composed of phospholipids. Phospholipid synthesis is catalyzed by membrane-bound enzymes, which themselves require pre-existing membranes for function.

Advancing design strategies in smart stimulus‐responsive liposomes for drug release and nanomedicine
BMEMat, EarlyView.Schematic illustration of stimulus‐responsive liposomes designed for controlled drug release and nanomedicine. The innermost circle represents different liposomal structures, including unilamellar, multilamellar, and multivesicular liposomes. The middle layer illustrates the responsive phospholipid components.

Marine silicon for biomedical sustainability
BMEMat, EarlyView.Schematic illustrating marine silicon for biomedical engineering. Abstract Despite momentous divergence from oceanic origin, human beings and marine organisms exhibit elemental homology through silicon utilization. Notably, silicon serves as a critical constituent in multiple biomedical processes.
