Abstract
Designing a biosensor is a complex engineering process requiring careful
consideration. This chapter takes a brief look at the design-to-fabrication process of
electrochemical biosensors and the evaluation of their performance. This review helps us
to build a roadmap for designing reliable and valuable biosensors for various
applications. The design roadmap consists of ten steps. The first section discusses the
importance of these steps, then some of them will be discussed in detail. This chapter
helps researchers to study the field of biosensors in a systematic and practical manner.
