Fast assembly of non-thiolated DNA on gold surface at lower pH
Jiang, Hui; Materon, Elsa M.; Sotomayor, Maria Del Pilar Taboada; Liu, Juewen (Elsevier, 2013-12-01)In a typical protocol for attaching DNA to a gold electrode, thiolated DNA is incubated with the electrode at neutral pH overnight. Here we report fast adsorption of non-thiolated DNA oligomers on gold electrodes at acidic ... -
