ABSTRACT:
A multi-layer blood culture sensor includes two matrices. The first matrix is a polymer that is permeable to carbon dioxide and water, but impermeable to protons. A pH sensitive absorbance based dye is encapsulated or isolated in the polymer. The second matrix is a polymer with a pH insensitive fluorescent dye encapsulated or isolated in the polymer. The matrices are spectrally coupled and are useful for the determination of microorganisms in a blood culture bottle.
