Embodiments herein relate to chemical sensors, devices and systems including the same, and related methods. In an embodiment, a medical device is included. The medical device can include a graphene varactor. The graphene varactor can include a graphene layer and a self-assembled monolayer disposed on an outer surface of the graphene layer through π-π stacking interactions. The self-assembled monolayer can provide a Langmuir theta value of at least 0.9. The self-assembled monolayer can include polycyclic aromatic hydrocarbons, tetraphenylporphyrins or derivatives thereof, metallotetraphenylporphyrins, or aromatic cyclodextrins. Other embodiments are also included herein.

A fluorescence quenching oxygen sensor (
100
) comprises a support (
102
) having coated thereon;
a compound having hard or soft acid groups (
104
); and
one or more pyrene compounds (
106
) represented by
Y—R-Pyrene (I)
attached to the compound having hard or soft basic groups;
wherein Y is a hard or soft basic group and R is an aliphatic linking group having 1 to 19 carbon atoms. The sensor can be used to prepare a fluorescence quenching oxygen detector.
