Abstract
An analytical system-on-a-chip can be used as an analytical imaging device, for example, for detecting the presence of a chemical compound. A layer of analytical material is formed on a transparent layer overlying a solid state image sensor. The analytical material can react in known ways with at least one reactant to block light or to allow light to pass through to the array. The underlying sensor array, in turn, can process the presence, absence or amount of light into a digitized signal output. The system-on-a-chip may also include software that can detect and analyze the output signals of the device.

1-30. (canceled)
A method of detecting a reactant comprising:
- exposing an analytical device having a plurality of materials patterned over an array of pixels of an imaging device to a reactant to selectively block light from the array, the array of pixels comprising light sensitive pixels and at least one reference pixel, and the reactant causing one or more of the materials to at least partially dissolve;
- and
- comparing output signals from the pixels representing an amount of light received at the pixels after being exposed to the reactant to reference output signals from the pixels representing an amount of light received at the pixels before being exposed to the reactant.
