Biosensors for cancer detection: A review

Abstract

The different types of biosensors and their critical applications across multiple domains for cancer detection have been analyzed in this review. The biosensors have been categorized according to their classes such as electrochemical, optical, mass-based to name a few and have been discussed here to emphasize their crucial applications in cancer detection. Cancer diagnosis has not been affordable and easy around the world due to advanced and expensive diagnostic technologies such as CT scans, MRIs, and other imaging procedures whereas biopsy is invasive and leads to many complications. Biosensors can play important role in early cancer diagnosis due to their portability, ease, low cost, and quick procedure. This article provides an in-depth analysis of several biosensors designed to identify biomarkers, as well as the concepts and detection limits to help detect cancer at its early stages. Latest developed technologies in the biosensing field have also been included in this article.
