Types of Biosensors and their Importance in Cardiovascular Applications

First published: 22 April 2022

Abstract

Cardiovascular disease (CVD) is a general nomenclature given to the group that includes diseases of the heart or blood vessels and describes any disease that affects the circulatory system. Biosensors can play a significant role in the early diagnosis of CVD as an alternative to time-consuming and expensive laboratory analysis. This chapter focuses on recent developments in biosensors used to detect cardiovascular biomarkers. An ideal cardiovascular biomarker should be highly specific with definite reference limits in order to provide valuable information for clinical assessment. The application of novel detection biosensors, such as electrochemical biosensors, piezoelectric biosensors, thermometric biosensors, and optical biosensors, is in the developmental stages, and there is the potential for rapid growth. The discovery of new potential biomarkers for CVDs along with current ones has increased the importance of fully validated cardiac biomarker biosensors and has led to new approaches for CVDs-based research.
