Impedance-based biosensing is a powerful technique for detecting biological analytes through changes in electrical impedance at the sensor interface. Gold electrodes are widely used in such sensors due to their excellent conductivity, biocompatibility, and ease of surface functionalization.
This thesis will cover the full development cycle of impedance biosensors, including the design and fabrication of gold electrode structures, their surface functionalization for selective biomolecule recognition, and the characterization of their sensing performance.
The research plan will include:
Design and microfabrication of gold electrode arrays
Surface functionalization of electrodes with bio-recognition elements (e.g., antibodies, aptamers)
Electrical impedance measurements and data analysis for biosensing applications
Optimization of sensor performance based on experimental results
An independent and methodical work style is expected, with a strong interest in bioelectronics and sensor technology.
