Bladder cancer is becoming more common and is now one of the top 11 cancers worldwide, according to the World Health Organization Cancer report. People who work with certain chemicals like those used in the dye and paint industries are at a higher risk, especially if they also smoke or have improper uro-hygiene. Scientists have discovered that urine from patients with bladder cancer contains specific substances, known as biomarkers, that may help to detect the disease in its preliminary stages. This project focuses on the promising biomarkers found in urine: one is a protein-based biomarker, and the other is a group of chemicals known as Volatile Organic Compounds (VOCs). The goal of this project is to develop a simple and accurate sensing unit that can detect these substances in urine. One will use a method similar to a home pregnancy test by the clinician, and the other will use a small sensing platform to detect the VOC chemicals. These tools could help doctors find bladder cancer earlier, making treatment more effective and saving lives.
