Introduction

Abstract

As implied in the title of this textbook, Biosensors: From Electric Circuits to Immunosensors, we are going to learn both electric circuitry (in relation to conventional sensors such as temperature sensors) and biosensors (such as antibody-based immunosensors), with equal emphasis on both. The overarching aim is to build an antibody-based immunosensor from scratch. Before we begin this textbook, let us define two important terms: sensors and biosensors. Let’s start with sensors.
