Surface chemistry modulates fibronectin conformation and directs integrin binding and specificity to control cell adhesion
TL;DR: An experimental framework to analyze adhesive mechanisms controlling cell-surface interactions is established and a general strategy of surface-directed control of adsorbed protein activity to manipulate cell function in biomaterial and biotechnological applications is provided.
Journal ArticleDOI
Integrin binding specificity regulates biomaterial surface chemistry effects on cell differentiation
TL;DR: It is demonstrated that surface chemistry modulates osteoblastic differentiation and matrix mineralization independently from alterations in cell proliferation, establishing surface-dependent differences in integrin binding as a mechanism regulating differential cellular responses to biomaterial surfaces.
Journal ArticleDOI
Surface chemistry modulates focal adhesion composition and signaling through changes in integrin binding.
TL;DR: Investigation of the effects of surface chemistry on focal adhesion assembly and signaling in a model system with well-defined chemistries revealed that surface chemistry modulates the structure and molecular composition of cell-matrix adhesions as well as focalAdhesion kinase (FAK) signaling.
Journal ArticleDOI
Suzuki Cross-Coupling Reactions Catalyzed by Palladium Nanoparticles in Aqueous Solution
TL;DR: Palladium nanoparticles stabilized by poly(N-vinyl-2-pyrrolidone) (PVP) are efficient catalysts for the Suzuki reactions in aqueous medium, suggesting that the catalytic reaction occurs on the surface of the Pd nanoparticles.
Journal ArticleDOI
Use of electroactive thiols to study the formation and exchange of alkanethiol monolayers on gold
David M. Collard,Marye Anne Fox +1 more
TL;DR: In this paper, mixed monolayers of hexadecanethiol and 16-(ferrocenyl carbonyloxy)hexadecan-ethiol were treated on gold with solutions of alkanethiols, which resulted in the replacement of approximately one third of the electroactive thiol.
