Purpose

Why a Biosensor?

Modern medicine has an increasing demand for real-time detection of chronic disease biomarkers such as cancer, diabetes, and heart disease. In the United States alone, about 1,660,290 cancer cases are expected to be diagnosed in 2013 [1]. Early detection improves survival rates and helps reduce treatment costs. The estimated economic impact for the next 10 years due to diseases combine to an estimated $4.2 trillion in 2023. With better prevention, detection, and treatment of chronic diseases, the estimated avoided cost in 2023 would be $1.1 trillion [2]. Current detection methods accrue high costs because of equipment and lab procedures necessary for readings. Few medical facilities in remote or underdeveloped areas are capable of running required equipment for these lifesaving tests. This limits the service to developed areas. Affordable alternatives lack sensitivity and are limited in range and real-time detection. The desire for an effective point-of-care system is ever growing. As disease diagnostics become readily available, the possibility of early disease detection will increase and eventually improve chances of remission and prevention.

Photonic Biosensor aims to design and test a  point-of-care biosensor that meets the requirements set by previous research on a photonic biosensor at LeTourneau University: label-free, low cost, highly sensitive, highly selective, and easy to integrate with a sample handling system.
