Technology
Researchers at the University of Iowa have developed a device for the accurate measurement of analytes in a biological or non-biological solution. This device, which could be implanted, is an optical sampling cell that contains a electromagnetic radiation source and a microspectrometer. The microspectrometer collects one or more parameters of the analyte in the infrared spectrum and reports the concentration data for this analyte in real-time. Because this device uses light absorption data for the analyte, it requires no additional reagents for analyte determination and thus provides continuous data without any recycling of components.
Background
The accurate, reproducible, real-time measurement of specific analytes present in biological fluids would provide physicians with the most-relevant and useful information on which to base treatment decisions. This type of analysis would prove particularly valuable for the measurement of glucose, important in diabetes maintenance, but could also be applied to other physiologically-relevant compounds, such as urea, lactate, triglycerides, cholesterol, etc.
