Biogenic Synthesis of Nanoparticles and Potential Applications: An Eco- Friendly Approach (2013, background): “In command to immobilize DNA onto the surfaces of nanoparticles, the DNA strands are frequently modified with meticulous functional groups that can work together powerfully with convinced nanoparticles [84].”
Electrochemical sensors based on metal and semiconductor nanoparticles (2009, background): “For example, Fang’s group has early developed an electrochemical DNA biosensor utilizing colloidal Au to enhance the DNA immobilization amount and ultimately lower its detection limit [17].”
A novel impedimetric biosensor based on graphene oxide/gold nanoplatform for detection of DNA arrays (2013, unknown): “[45] assembled the AuNPs (16 nm in diameter) on a cysteamine-modified gold electrode and discovered that the immobilization quantities of thiolated probe DNA on the modified electrode were increased more than that on a bare gold electrode.”
Nanobiosensors: Concepts and Variations (2013, methodology): “In this reference, colloidal gold based nanoparticles have been used to enhance the immobilization of DNA on gold electrodes which has significantly increased the efficiency of an overall biosensor by further lowering the detection limit [35].”
