Thiolated Polyethylene Glycol

Photochemical reactions can cause significant transformations of manufactured nanomaterials and their surface coatings in sunlit environments. In this study, loss of thiolated polyethylene glycol from gold nanoparticle surfaces by chain scission was observed under UV irradiation and resulted in diminished colloidal stability.

Here we present the use of surface nanopatterning of covalently immobilized BMP-2 and integrin selective ligands to determine the specificity of their interactions in regulating cell adhesion and focal adhesion assembly. Gold nanoparticle arrays carrying single BMP-2 dimersare prepared by block-copolymer micellar nanolithography and azide-functionalized integrin ligands (RGD peptides or α<sub>5</sub>β<sub>1</sub>integrin peptidomimetics) are immobilized on the surrounding polyethylene glycol alkyne by click chemistry.
