In general, the change in the index of refraction can be measured more accurately than the change in the absorption spectrum, for example, using microring resonators and fiber Bragg gratings. Therefore, sensors based on the refractive index change could be more sensitive than the sensors based on the absorption spectrum change. The details of how nitroaromatic explosive molecules interact with the chromophores in the polymer matrix requires further study. Initial observations suggest that because nitroaromatic explosive molecules are highly electron-deficient, that chromophores have an electron-rich donor and bridge, and that both nitroaromatic explosives and chromophores are highly polar, explosive molecules and chromophores have a strong tendency to interact with each other.

The interaction between explosives and the polymer takes place in two steps.
