Sensors and methods are provided that include a diamond material containing a nitrogen vacancy center, the diamond material being configured to be exposed to an environment comprising one or more gases, an optical light source configured to excite the nitrogen vacancy center of the diamond material with an optical light beam produced therefrom, a detector configured to detect a signal originating from the diamond material in response to the optical light beam exciting the nitrogen vacancy center, and the capability of analyzing the signal to identify a specific gas in the environment. Also included are levitated spin-optomechanical systems capable of elevating in a vacuum a diamond material containing a nitrogen vacancy center, applying microwave radiation to the diamond material for controlling and flipping the electron spin of the nitrogen vacancy center, and monitoring electron spin of the nitrogen vacancy center.
