1. A device for determining exposure of an object to an environmental condition comprising:
- a fluorescent marker that is capable of a change in fluorescence output upon exposure to an environmental condition; and
an object associated with said fluorescent marker wherein said change in fluorescence output is capable of being associated with said object'"'"'s exposure to said environmental condition.

Abstract
The present disclosure relates to a fluorescence marker such as quantum dots and their use as sensors which may rely upon a change in fluorescence output upon exposure to a given environmental condition. The variation in fluorescence output may then be utilized as an indication of exposure to a given environmental condition.
