Previously, we developed a multifunctional envelope-type nano device (MEND) for efficient delivery of nucleic acids. For tumor delivery of a MEND, PEGylation is a useful method, which confers a longer systemic circulation and tumor accumulation via the enhanced permeability and retention (EPR) effect. However, PEGylation inhibits cellular uptake and subsequent endosomal escape. To overcome this...
Liposomes are nanocarriers consisting of a phospholipid bilayer, similar in composition and structure to cell membrane. Such feature provides several possibilities related the transport delivery biologically active substances specific cells organisms. It is now becoming more popular modify lipid carrier shells achieve higher specificity efficiency into cells, reduce immunogenicity. The article ...
BACKGROUND Poly (ethylene glycol) (PEG) has attracted broad interest for tissue engineering applications. The aim of this study was to synthesize 4-arm -PEG-20kDa with the terminal group of diacrylate (4-arm-PEG-DA) and evaluate its dual functionality for decellularized porcine aortic valve (DAV) based on its mechanical and biological properties. METHODS 4-arm-PEG-DA was synthesized by graft ...
