Purpose of the Study:
- To fabricate and characterize a conductive gold leaf-based microfluidic platform.
- To evaluate its potential for controlled drug delivery using essential oils.
Main Methods:
- Fabrication of a microfluidic chip using xurography and gold leaf.
- Electrochemical impedance spectroscopy (EIS) to analyze chip response.
- Exposure of the chip to peppermint and eucalyptus essential oils (EOs) at varying concentrations and time intervals.
Main Results:
- Increased electrical resistance observed with longer exposure to EOs.
- Eucalyptus oil exhibited stronger degradable effects, leading to higher resistance than peppermint oil.
- Specific resistance values recorded for different EO concentrations and exposure times.
Conclusions:
- The gold leaf microfluidic platform shows promise for controlled drug delivery.
- The device's electrical response is sensitive to essential oil exposure.
- Findings support the development of microfluidic devices for diverse biomedical applications.
