Coating of POPC Giant Liposomes with Hydrophobized Polysaccharide
Chemistry Letters, 1998Abstract POPC giant liposomes were incubated with pullulan that was hydrophobized by cholesteryl groups and labelled by a fluorescent marker (FITC). Confocal laser microscopy clearly showed coating of the outer surface of the liposomes with the polymer.

Uniformly-sized giant liposome formation with gentle hydration
2011 IEEE 24th International Conference on Micro Electro Mechanical Systems, 2011This paper describes a methodology that realizes uniformly-sized liposome arrays with gentle hydration. The system consists of a dried lipid pattern on a substrate that is a micropatterned polymer thin film on an indium-tin-oxide (ITO) glass slide. An electrospray deposition (ESD) method was applied to obtain the lipid patterning at the polymer pattern

Spreading of giant liposomes on anisotropically patterned substrates
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2013The dynamic spreading of giant liposomes on anisotropically patterned substrates is investigated experimentally on vertically fixed spreading substrates. The giant liposomes are prepared through electroformation method. The substrates with anisotropic grooves on the surfaces are fabricated on silicon wafers by photolithography and dry etching.

Reconstruction of motile actin networks in giant liposome
2010 International Symposium on Micro-NanoMechatronics and Human Science, 2010To construct a simple model cellular system exhibiting the property of self-propelled motion, cell-sized giant liposomes encapsulating desired amounts of actoHMM, a mixture of actin filament (F-actin) and heavy meromyosin (HMM, an actin-related molecular motor), have been prepared.

Transmembrane transport of multicomponent liposome-nanoparticles into giant vesicles
Chinese Physics B, 2022With the emergence and rapid development of nanotechnology, the nanoparticles hybridized with multicomponent lipids are more and more used in gene delivery. These vectors interact with the cell membrane before entering into the cell. Therefore, the nature of this interaction is important in investigating multicomponent liposome-nanoparticle (MLP ...

Giant liposomes: from membrane dynamics to cell morphogenesis
Current Opinion in Colloid & Interface Science, 1999Although a lipid bilayer is only several nanometers in thickness, giant liposomes (GLs) make it possible to observe the dynamic features of individual membrane vesicles in real time with optical microscopy. Recent progress in GL preparation methods allows one to make reproducible image analyses of essential characteristics of membrane vesicles ...

Novel method to form giant liposome entrapping DNA
Macromolecular Symposia, 1996AbstractWe report a new method to prepare giant liposome with the size of several tens micrometers, entrapping DNA molecule within the closed phospholipid membrane. The formation of such liposomes has been confirmed through the observation with fluorescence microscopy.

Location of Magnetic and Fluorescent Nanoparticles Encapsulated inside Giant Liposomes
The Journal of Physical Chemistry B, 2008In this paper, we demonstrate the production of highly magnetic and fluorescent giant vesicles by encapsulating gamma-Fe2O3-rhodamine B nanoparticles. The liposomes containing the nanoparticles were made of 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC).

In situ precipitation of magnetic fluid encapsulated in giant liposomes
Journal of Colloid and Interface Science, 2010It is well known that adding salt to a colloidal solution stabilized by electrostatic repulsions can induce its destabilization. When this colloidal solution is encapsulated inside liposomes an in situ precipitation can be induced by slightly modification of the environment: application of a magnetic field in the case of magnetic particles or increase ...
