Claim 1:
2. A method for detecting cancerous status of a biological sample, comprising:
calculating a charge transfer resistance (Rct) of an electrochemical impedance spectroscopy (EIS) associated with lipid secretion of a biological sample, the biological sample comprising a biological sample suspected to be cancerous, calculating the Rct of the EIS associated with the lipid secretion of the biological sample comprising:
putting the lipid secretion of the biological sample in direct contact with an array of hydrophobic conductive nanostructures grown on three-integrated electrodes of a biosensor by dropping peripheral aqueous media of the biological sample on the array of hydrophobic conductive nanostructures, the peripheral aqueous media of the biological sample comprising the lipid secretion of the biological sample;
recording the EIS of the lipid secretion of the biological sample being in direct contact with the array of hydrophobic conductive nanostructures using an electrochemical analyzer; and
measuring a diameter of a semicircular curve of the recorded EIS; and

detecting a cancerous state for the biological sample, comprising:
detecting a cancerous state for the biological sample if the calculated Rct is equal to or more than a threshold value of 10 KΩ; or
detecting a normal state for the biological sample if the calculated Rct is less than the threshold value of 10 KΩ.
