Nano-Amplification Strategy Using Charge-Based Capacitance Measurement for Pathogenic Bacteria Detection
Öz
Objective: This work will present a nano-amplifi cation strategy for microfabricating Multi-Lab-On-Single-Chip (MLoC) system to enhance the level of
detection and also reduced the number of probe pads for clinical and health care applications, such as pathogenic disease.
Material and
Method:
The Charge-Based Capacitance Measurement (CBCM) technique used Complementary Metal-Oxide-Semiconductor (CMOS) with 350
nm technology, the implementation material is doped silicon. The system employs an interdigitated capacitor structure, charge based
capacitance measurement circuitry to detect and process the variation of the capacitance, which is a function of the permittivity in the
presence of targeted bacteria that is applied to the sensing capacitor but not to the reference one.
Findings and
Results:
The system appeared good sensitivity for low level concentration of bacterial comparing to the literature results. The circuit was measuring
the capacitance changes around 100 aF. The noise at the output of the circuit is around 78.7µV.
Conclusion: CMOS biosensor-based charge-based capacitance measurement system has been fabricated, testing and experimentally validated for
bacterial pathogens cell detection. Three important requirements of such biosensor systems including functionalized sensing capacitance,
passivating the reference capacitance and interface circuit were discussed. The system provides a rapid, low power, and miniaturized
platform that can be mass-produced.
