Dendrimer-encapsulated and cored metal nanoparticles for electrochemical nanobiosensing

• Applying dendrimer-encapsulated metal nanoparticles to electrochemical biosensing.
• Recent advances in electrochemical biosensors are based on nanosized dendrimers.
• Dendrimer-core metal nanoparticles provide platform for electrochemical biosensors.

We discuss nanosized dendrimers from the point of view of electrochemical-biosensor design. We review electrochemical biosensors based on dendrimer-encapsulated metal nanoparticles (NPs) and their various applications (e.g., measurement of small biological and toxic molecules, detection of DNA, and immunosensing of disease biomarkers). Finally, we discuss some future applications of electrochemical biosensors based on dendrimer-encapsulated metal NPs.
