Abstract:
A micro sensor device for measuring a concentration of a substance within a sample comprising:at least one integrated sensor head module having a tip portion being sized and adapted to be inserted into a sample through intercellular gaps or through a cell membrane, said module including a light source for emitting a beam of light into and through the tip portion, said tip portion being capable of transmitting light and having an exterior surface treated to interact with a substance within a sample to produce a reflected pattern of light, said module further including a detector for receiving the reflected pattern of light; anda body portion coupled to the integrated sensor head module, the body portion comprising a processor operatively coupled to the light source and the detector, the processor for controlling the light source for emitting the beam of light, for receiving the pattern of reflected light from the detector, and for processing the reflected pattern of light to determine the concentration of a substance within a sample.
