Peg long circulation
WebPoly (ethylene glycol) (PEG) is the polymer of choice to produce stealth nanocarriers. This neutral, flexible, and hydrophilic material can in fact properly produce surface barrier layers that reduce the adhesion of opsonins present in the blood serum on the nanoparticles making them “invisible” to phagocytic cells. WebSep 28, 2008 · Incorporation of PEG-PE reduced the rate of total liver uptake about 4-fold for liposomes of either size and shifted the H/M ratio to 60:40 for the smaller vesicles and to 40:60 for the larger ones. For both liposome sizes, PEG-PE apparently causes a shift in intrahepatic distribution in favor of the macrophages.

WebPolyethylene glycol (PEG; / ˌ p ɒ l i ˈ ɛ θ əl ˌ iː n ˈ ɡ l aɪ ˌ k ɒ l,-ˈ ɛ θ ɪ l-,-ˌ k ɔː l /) is a polyether compound derived from petroleum with many applications, from industrial manufacturing to medicine.PEG is also known as polyethylene oxide (PEO) or polyoxyethylene (POE), depending on its molecular weight.The structure of PEG is commonly expressed as … WebPEGylated RESOMER ® can be used also for the formulation of emulsifier free nanoparticles and nanocapsules. The particles are known to show long circulation times due to the stealth effect of PEG which reduces the interaction with the system. In conclusion, RESOMER ® polymers are biodegradable and diverse materials for a wide range of applications.
