Biosensors and Biomarkers: Promising Tools for Cancer Diagnosis

Abstract

Due to its high death rate, cancer has been one of the most researched diseases all over the globe. A biosensor is an analytical device, used for the detection of an analyte that combines a biological component with a physicochemical detector. Nowadays, there is an increasing interest in developing cancer biosensors as they show superior analytical performance and real-time measurement. Further with recent advances in molecular biology and bioengineering, biosensors diagnosis of cancer has taken a new direction. Due to high specificity and promise of early diagnosis, biosensors are prime candidates for current and future cancer diagnosis. With ever increasing list of biomarkers associated with various types of cancer and innovation in bioengineering, the future for diagnosis of cancer seems promising. In present article we have discussed various biosensors and biomarkers as a promising tool for cancer diagnosis.
