Abstract
Graphene quantum dots GQD can be used for diagnosis for its high Optical properties. Quantum dots which were synthesized by pyrolysis method, used for detection of acetone as in diabetes mellitus breath. In this projects, the Graphene quantum dots were characterize by TEM, FTIR and UV-vis. The TEM graphs reveal that the sizes of GQDs are in average about 4.48 nm.The UV-vis and FTIR spectrums show that the responses to exhaled breath cause to quenching or decrease optical intensity due to acetone. Acetone molecules as simplest ketone are deexcited to initial state because of collision with other molecules, especially with oxygen-containing functional groups and the spectrum plots show the optical quenching of GQDs solution.
