研究目的
To fabricate and characterize an aluminium interdigitated electrode hybrid with ZnO for the detection of cardiac troponin T biomarker.
研究成果
The fabricated aluminium interdigitated electrode hybrid with ZnO demonstrated high sensitivity and selectivity for the detection of cardiac troponin T biomarker. The sol-gel method was effective for the deposition of ZnO thin film on Al IDE. The device has potential applications in early diagnosis of cardiovascular diseases.
研究不足
The study is limited by the sensitivity and selectivity of the device towards cTnT biomarker, which may be affected by the fabrication process and the quality of the ZnO thin film. Further optimization of the fabrication process and device design may be required to improve performance.
