A blood sugar detecting system using emission quantum dots is provided. A non-cyclodextran carbohydrate-containing molecule and a glucose-recognizing molecule respectively bind to an emission quantum dot and a light-absorbing molecule to form the blood sugar measuring system. When the non-cyclodextran carbohydrate-containing molecule and the glucose-recognizing molecule bind together to bring the emission quantum dot very close to the light-absorbing molecule, a fluorescence resonance energy transfer effect is happened between them. Glucose can compete with the non-cyclodextran carbohydrate-containing molecule for the binding site of the glucose-recognizing molecule to detect glucose concentration variation.
