Chappelle earned a Masters in Science with a focus on biochemistry in 1954 but never completed a Ph.D. He added the chemicals to different substances, and if those substances emitted light, that meant there was a living thing present. Unbeknownst to her or her family, a sample of her cells had been sent to a nearby tissue lab, where instead of dying quickly, they doubled every 20 to 24 hours according to Johns Hopkins. Working in NASA's Remote Sensing Division, he was a specialist in the field of luminescence light without heat and bioluminescence warm light produced by living organisms.

The susceptibility of bacteria, particularly those derived from body fluids, to antimicrobial agents is determined in terms of an ATP index measured by culturing a bacterium in a growth medium, assaying the amount of ATP in a sample of the cultured bacterium by measuring the amount of luminescent light emitted when the bacterial ATP is reacted with a luciferase-luciferin mixture, subjecting the sample of the cultured bacterium to an antibiotic agent and assaying the amount of bacterial adenosine triphosphate after treatment with the antibiotic by measuring the luminescent light resulting from the reaction, whereby the ATP index is determined from the values obtained from the assay procedures.
