Apparatus and methods of determining the chemical properties of a composite material using infrared spectroscopy are disclosed. The apparatus includes a signal generator controlled by a master microcontroller, a plurality of data acquisition channels, each channel containing a microcontroller, a host computer that processes and stores measured values, and a communication line between the host computer and the master microcontroller. More specifically, the cache server compares transform criteria to a uniform resource identifier portion and a header portion associated with the request. The subject system thus reduces computation and the number of bits required to represent features by first scaling the image and then tiling the image in the same proportion. The structure is formed by providing a mesoporous template, filling the mesopores with an organic precursor, polymerizing the organic precursor, pyrolyzing the polymerized organic precursor, and etching away the template. A biosensor according to example embodiments may have a reduced analysis time.
