What is it about?

Sarcosine is told to be a potential biomarker for prostate cancer. Though low in quantity its detection is possible with the help of sensors. The sensors used are colorimetric and electrochemical which means the output will be optical and voltage-based, respectively, for indicating the presence of Sarcosine. The available sensors are enlisted along with its future perspectives and commercial potential.

Why is it important?

Through this review paper, we have provided a list of electrochemical and colorimetric sensors that can be implemented for sarcosine detection while screening for prostate cancer. The essential features and drawbacks of each sensor has been jotted along for comparison purpose.


This article made us explore variety of fields in cancer research, biomedical potential and the future of technology in healthcare. It was a great experience to research on the same and provide the details in layman's terms. The ultimate goal was to deliver a comparative study on the available sensors for sarcosine detection and provide insights on the area of improvement. Hope you find this article helpful while developing or researching on sensors for biomedical applications.
