  Abstract. Liposomes that destabilize at mildly acidic pH are efficient tools for delivering water-soluble drugs into the cell cytoplasm. However, their use in vivo is limited because of their rapid uptake from circulation by the reticuloendothelial system. Lipid-anchored polyethylene glycol (PEG-PE) prolongs the circulation time of liposomes by steric stabilization. These findings support the use of sterically stabilized cationic liposomes to significantly enhance the therapeutic ef ficacy of CpG ODN. The Journal of . Volume , Issue 2, 14 August , Pages Biochimica et Biophy Sterically stabilized liposomesCited by:   The blood clearance curve of In encapsulated in sterically stabilized pH-sensitive liposomes (Fig. 5A) was similar to that of previously developed liposomes with prolonged circulation time, and a substantial percentage of liposomes (%) remained in the blood after 24 h. In contrast, the radioactive marker encapsulated in regular pH.

Lipids and lipid-based delivery vehicles, namely liposomes, micelles, and micro/nano bubbles have become the most researched and clinically applied area in the field of nanomedicine.   Versatility in lipid compositions showing prolonged circulation with sterically stabilized liposomes.

Preparation of Liposomes The choice of lipids for liposome research is entirely dependent on the system to be studied. Biological assays may require mixtures of lipids while pharmacokinetics of drug delivery are dramatically affected by the phase .

A liposome is a spherical vesicle having at least one lipid liposome can be used as a vehicle for administration of nutrients and pharmaceutical drugs. Liposomes can be prepared by disrupting biological membranes (such as by sonication).. Liposomes are most often composed of phospholipids, especially phosphatidylcholine, but may also include other lipids, such as egg.   Solubilized paclitaxel amount increased linearly with an increase in lipid concentration.
