Opis

Opis ogólny

Poly(ethylene glycol) (PEG) is a synthetic, hydrophilic, biocompatible polymer with widespread use in biomedical and other applications. PEGs are non-toxic, FDA-approved, generally non-immunogenic, and frequently used in many biomedical applications including bioconjugation, drug delivery, surface functionalization, and tissue engineering. In drug delivery, PEGs can be used as linkers for antibody-drug conjugates (ADCs) or as a surface coating on nanoparticles to improve systemic drug delivery.

Zastosowanie

Poly(ethylene glycol) (PEG) has been used as a coating agent for the synthesis and in vitro safety assessment of magnetic bacterial cellulose (MBC) pellicles, performed on porcine aortic smooth muscle cells (PAOSMC). PEG provides a compatible surface for cell culture, since uncoated iron oxide NPs are considered cytotoxic to cells. It has also been used as a plasticizer in investigating the effectiveness of polyvinylpyrrolidone microneedles for transdermal delivery of functional collagen using porcine skin, adult human skin analog and human foreskin. Microneedles obtained, were reportedly characterized by various analytical and bio-analytical techniques.
