PMID: 21990942
Appl Phys Lett. 2011 Sep 05;99(10):103702-1037023. doi: 10.1063/1.3635783. Epub 2011 Sep 08.

An organic-inorganic hybridization strategy has been proposed to synthesize polymerizable lipid-based materials for the creation of highly stable lipid-mimetic nanostructures. We employ atomic force microscopy (AFM) to analyze the surface morphology and mechanical property of electrospun cholesteryl-succinyl silane (CSS)...

Penetratin (RQIKIWFQNRRMKWKK) enters cells by different mechanisms, including membrane translocation, thus implying that the peptide interacts with the lipid bilayer. Penetratin also crosses the membrane of artificial vesicles, depending on their phospholipid content. To evaluate the phospholipid preference of...
