6 Biosensors Based on Nanomaterials and Nanodevices
introduce electrochemiluminescence (ECL) biosensors in Chapter 9, where photoemis-
sion is generated by an electrochemical reaction triggered with proper electropotentials.
In particular, this chapter highlights the enhancement of ECL by various nanomaterials. It
also links optical methods with electrical methods in the next section.
1.5.2 Section II: Electrical Biosensors
The electrical methods are attractive since the signal can be directly recorded using
modern electronics for multiplex portable systems. This book gives a thorough review
of carbon materials, such as diamond, CNTs, graphene ...
