Electrochemical genosensors for biomedical applications based on gold nanoparticles
Two cold nanoparticles-based genomagnetic sensors designs for detection of DNA hybridization are described. Both assays are based on a magnetically induced direct electrochemical detection of gold tags on magnetic graphite-epoxy composite electrodes. The first design is a two strands assay format that consists of the hybridization between a capture DNA strand which is linked with …
