Handheld raman body fluid analyzer
WO 2007089540 A3
Methods and apparatus for in vitro detection of an analyte in a body fluid sample using low resolution Raman spectroscopy are disclosed. The body fluid analyzer includes a disposable strip for receiving a sample of body fluid on a target region, the target region including gold sol-gel to provide surface enhanced Raman scattering. A light source irradiates the target region to produce a Raman spectrum consisting of scattered electromagnetic radiation that is separated into different wavelength components by a dispersion element. A detection array detects at least some of the wavelength components of the scattered light and provides data to a processor for processing the data. The results of the processed data are displayed on a screen to inform a user about an analyte within the body fluid sample.
