Immobilization of DNA molecules on the metal surface through alkyl amine for biosensor applications

Efforts to immobilize DNA molecules directly onto the metal surface have been carried out by many researchers. At present, deposition of DNA onto the metal surface of gold is usually carried out through alkylthiol molecules. In this work, DNA molecules were succesfidly deposited on the metal surface...
