Copolymer Coatings for DNA Biosensors: Effect of Charges and Immobilization Chemistries on Yield, Strength and Kinetics of Hybridization by Luka Vanjur, Thomas Carzaniga, Luca Casiraghi, Giuliano Zanchetta, Francesco Damin, Laura Sola, Marcella Chiari, Marco Buscaglia

“…Copolymers of <i>N</i>, <i>N</i>-dimethylacrylamide bringing either a different type or density of sites for covalent immobilization of DNA probes, or different backbone charges, were used to functionalize the surface of a Reflective Phantom Interface multispot biosensor made of a glass prism with a silicon dioxide antireflective layer. By analyzing the kinetic hybridization curves at different probe surface densities and target concentrations in solution, we found that all the tested coatings displayed a common association kinetics of about 9 × 10⁴ M⁻¹·s⁻¹ at small probe density, decreasing by one order of magnitude close to the surface saturation of probes. …”
