In this work, ZnSe nanodots were synthesized in the cavity of the ferritin from horse spleen (HsAFr), where the ferritin is a self assembled iron storage protein with a 6 nm polypeptide cage and two-dimensional ZnSe-ferritin nanodots by simple touch method with modification of silicon wafer surface was obtained. Then, the PL intensity of the QDs in soultion and array were studied accompanying its conjugation reaction with gammaaminobutyric acid (GABA) in order to utilize this material as a biosensor. In addition, GABA was conjugated to QDs surface by an active ester coupling reaction. Finally, the PL study was performed on the mixtures of GABA and other neurotransmitters to confirm the selectivity of the ZnSe-ferritin nanodot array for GABA. |
