Disclosed herein is a method of positively detecting toxic materials within a sample, the method including contacting sub-mitochondrial particles with an electron donor. The electron donor is reacted with an electron transfer system of the sub-mitochondrial particles to produce a reactant. A pH indicator has its pH adjusted to be in a range of 9 to 11. The pH indicator is added to each reactant. Color changes in the pH indicator permit the detection of toxins present in the sample.
