Abstract

A microfluidic analysis system (100, 500) for optically analyzing a substance includes a light source (225) having a plurality of selectable single-wavelength light sources (225), a substance presentation member optically coupled to the light source (225), and an optical detection system associated with the substance presentation member.

Description

Background technique [0001] More recently, trends in biomedical diagnostics and drug discovery indicate a rapid increase in the use of high-speed and high-throughput chemical detection, chemical screening, and compound synthesis. Several systems utilize instruments that require large sample volumes, are difficult to transport, and are expensive. Efforts are underway to speed up drug delivery and treatment, curb high healthcare costs, and provide decentralized biomedical diagnostics such as diagnostics for healthcare, among other futuristic technologies. These efforts generally focus on increasing the miniaturization, integration, and automation of fluid analysis systems. [0002] Fluid analysis systems traditionally use several components, including a light source, a wavelength selective system, a sample presentation system, and a detection system to analyze a patient's fluid. However, each of these components sometimes adds prohibitive costs to the overall fluid analysis sy...
