Ozonization and cyclic voltammetry as efficient methods for the regeneration of gelatin-coated SPR chips.

The application of ozonization and cyclic voltammetry for the regeneration of gold chips containing a chemisorbed gelatin layer is reported. The efficiency of the regeneration process was analyzed using various surface analysis techniques indicating a complete removal of the biopolymer layer. The current findings open up perspectives for regeneration and multiple application of gold chips for SPR measurements.

Immobilization of cytochrome c on cysteamine-modified gold electrodes with EDC as coupling agent.

Cyclic voltammetry has been applied for the characterization of cross-linked horse heart cytochrome c (HHC) on cysteamine-modified gold electrodes. The cross-linking, i.e.
