Implantable sensor and method for detecting at least one analyte in a body fluid

Abstract

Disclosed is a fully implantable sensor for detecting at least one analyte in a sample of body fluid. The sensor has a measurement chamber plate that receives the sample of bodily fluid and a quantum cascade laser illumination source that generates an illumination light beam in the spectral range and transmits it to the measurement chamber plate. The illumination light beam at least partially illuminates the measurement chamber plate and the measurement chamber plate generates a reflection light beam in response to the illumination by the illumination light beam. The reflection light beam at least partially illuminates the sample of body fluid within the measurement chamber plate. An optical detector detects at least one property of the reflection light beam and generates a sensor signal dependent on the presence of the analyte. A controlled evaluates the sensor signal. A method using an inventive fully implantable sensor is also disclosed.
