We have successfully demonstrated a chemically modified PVA-PEG-b, where the modification by the PEG-b linker resulted in the altered decay of nanofibers.
With the modifications by hydrophilic PEG, the contact angle was dramatically dropping to 84.6 and 88.2 in mPEG-PCL-mPEG and mPEG-PCL-mPEG/HA scaffold, respectively.
The influences of initial P concentration, slag dose and modification by polyethylene glycol (PEG), an effective agent for generation of porous materials, were investigated to determine the optimal conditions for P removal by AOD slag.
In addition, the half-life can be further extended by PEG modification.
A study concluded that the biological toxicity of chemical modifications of PEG-CNTs is influenced by PEG.
Some of examples regarding PEG modification by covalent and noncovalent bonding are presented elsewhere [ 98].
A novel method of surface modification by grafting hydrophilic poly ethylene glycol) (PEG) chains onto the surface of a thin-film composite (TFC) polyamide reverse osmosis (RO) membrane was performed.
We have recently reported that PEGylated liposomes (PL) are cleared rapidly from the blood circulation when they are administered twice in the same rat at certain intervals, even if the liposomes are sterically stabilized by a surface modification with PEG (referred to as the accelerated blood clearance (ABC) phenomenon, J. Control.
Going further in the surface modifications, the application of polymer coatings on the surface of Au nanoparticles and nanorods can significantly reduce the cytotoxicity, e.g., by PEG, PAA, PAH, starch modifications.
Thus, the molecular size, which was determined by the degree of PEG modification and PEG molecular weight, influences the specific activity and anti-tumour effects of hybrid TNF-alpha.
