Abstract:
An optical sensor assembly adapted for sensing analyte content of a plurality of samples, said optical sensor assembly comprising:a substrate web of predetermined length, said substrate web being substantially gas impermeable and optically transparent in a predetermined spectral range; a plurality of elongated sensor stripes extending in parallel, spaced relation along the length of said web, each one of said plurality of sensor stripes adapted for providing an optically discernible response to presence of at least one analyte, said optical sensor adapted for selective analyte-sensing contact with the plurality of samples, wherein each one of the plurality of samples are selectively superimposable with each one of said plurality of elongated sensor stripes at one of a plurality of discrete sample positions along the lengths thereof; and at least one sample chamber superimposable with each of said plurality of elongated sensor stripes at one of said plurality of discrete sample positions along the lengths thereof, said optically discernible response being substantially identical at said plurality of discrete sample positions and wherein said at least one sample chamber is adapted for alternately maintaining individual ones of the plurality of samples in said analyte-sensing contact.
