Abstract Carbon Quantum Dots (CQDs), which was synthesized from succinic acid and glycerol through the esterification reaction, was used to increase the efficiency of fluorescence intensity as well as with chitosan encapsulation. The results showed the achieved highest fluorescence intensity. The encapsulation of 0.10 mg/mL CQDs and 0.20% chitosan showed the highest the percent of encapsulation was 17.954±0.73. The cytotoxicity of Carbon Quantum dots and chitosan had been studied with Staphylococcus aureus by using 0.25 mg/mL Carbon Quantum dots, 0.20% chitosan and CQDs-CH (0.10 mg/mL CQDs, 0.20% w/v chitosan). These results indicated that 0.25 mg/mL Carbon Quantum dots, 0.20% chitosan and CQDs-CH (0.10 mg/mL CQDs, 0.20% w/v chitosan) are exhibited non-toxicity for Staphylococcus aureus, which confirms that the Carbon Quantum dots and chitosan acted as eco-friendly biological. Moreover, the trial of antibiotics (vancomycin) together with the main material (CQDs-CH) was determined as being a biosensor for S. aureus detection. The results of this research can be used as a guideline for the use of Carbon Quantum dots for further biosensor applications.
