Abstract: A method for targeted drug delivery. The method includes injecting a drug composition into a cancer patient's body including forming an ion of an anticancer agent of the drug composition in bloodstream of the cancer patient, placing an electrically conductive element in a region next to a tumor location inside the cancer patient's body, and delivering the drug composition to the tumor location. Delivering the drug composition to the tumor location includes electrostatically trapping the drug composition within the tumor location by applying an electrostatic field with an opposite sign of electric charge to a sign of electric charge of the ion of the anticancer agent to the electrically conductive element.

Abstract: A method for detecting cancerous status of a biological sample. The method includes calculating a charge transfer resistance (Rct) of an electrochemical impedance spectroscopy (EIS) associated with lipid secretion of a biological sample, detecting a cancerous state for the biological sample responsive to the calculated Rct being equal to or more than a threshold value, and detecting a normal state for the biological sample responsive to the calculated Rct being less than the threshold value. The biological sample includes a biological sample suspected to be cancerous.

Abstract: A method for diagnosing COVID-19 infection of a person. The method includes acquiring a sputum sample of the person, measuring a level of reactive oxygen species (ROS) in the sputum sample, and detecting a COVID-19 infection status of the person based on the measured level of ROS. Measuring the level of ROS in the sputum sample includes recording a cyclic voltammetry (CV) pattern from the sputum sample and measuring a current peak of the recorded CV pattern. Detecting the COVID-19 infection status of the person based on the measured level of ROS includes detecting the person is infected with COVID-19 if the measured current peak is in a first range of current peaks and detecting the person is not infected with COVID-19 if the measured current peak is in a second range of current peaks.

Abstract: A method for detecting sentinel lymph nodes during surgery. The method includes injecting a crystalloid solution into a region, measuring a plurality of electrical parameters utilizing a sensor, and detecting a sentinel lymph node among a plurality of lymph nodes based on the plurality of electrical parameters. The region is associated with a tumor in a patient's body. Measuring the plurality of electrical parameters includes measuring each respective electrical parameter of a respective lymph node of the plurality of lymph nodes. The plurality of lymph nodes are associated with the tumor. The sentinel lymph node is located at a shortest distance from the tumor among the plurality of lymph nodes.

Abstract: A method for detecting cancerous status of a suspected lymph node (LN) to be cancerous. The method includes measuring fatty acid oxidation (FAO) in the suspected LN by measuring a charge transfer resistance (RCT) associated with the suspected LN, and detecting, utilizing one or more processors, a cancerous status of the suspected LN. Detecting the cancerous status of the suspected LN includes detecting the suspected LN is cancer involved if the measured RCT is less than a reference RCT value, or detecting the suspected LN is healthy if the measured RCT is more than the reference RCT value.
