Cells in the body do not grow as isolated entities attached to a flat surface. They reside in a hydrated extracellular matrix, where they continuously experience spatial confinement, material stiffness, adhesion signals, nutrient diffusion, enzymatic degradation, and changes in growth factors. ...
Biomaterial scaffolds commonly used in tissue engineering and cell biology research are often homogeneous: they have uniform composition, uniform stiffness, and uniformly distributed signaling molecules. In real tissues, however, the cellular microenvironment is highly organized.
Polyethylene glycol (PEG) is a hydrophilic polymer composed of repeating –CH₂–CH₂–O– units. Owing to its excellent water solubility, low toxicity, low immunogenicity, and good biocompatibility, pharmaceutical-grade PEG has been widely used in injectable formulations, ...
Polyethylene glycol (PEG) is a family of linear polyether polymers produced by the stepwise addition polymerization of ethylene oxide with water or ethylene glycol.
Poly(ethylene glycol) (PEG) is a widely used hydrophilic polymer that is commonly employed for the covalent modification of proteins, peptides and small-molecule drugs. By introducing PEG chains onto drug molecules or the surfaces of delivery carriers (PEGylation), their physicochemical ...
Thiol PEG is a thiol-terminated polyethylene glycol (PEG)-containing reagent with either a methyl ether, hydroxyl or carboxylic acid group at the other end. These reagents have defined molecular weights and spacer lengths and are used for modifying surfaces such quantum dots, self-assembled ...
Aminooxy PEG Linkers can be used in bioconjugation through the reaction of the aldehyde group with aminooxy to form aldoxime. It is much more stable than hydrazone and imine. In most of cases, it can be used directly without reduction while hydrazine and imines bond normally need be reduced to ...
