A system for diagnosing metastasis in a metastatic-suspicious sample, including: a bio-chip, an electrical signal extraction board and a processor. The bio-chip includes a biosensor including a substrate, an array of electrodes, where the array of electrodes is patterned on the substrate and at least one Human Umbilical Vein Endothelial Cell (HUVEC) which is adhered on the substrate and on the array of electrodes forming a biological trap for a metastatic cell. A metastatic-suspicious sample may be introduced onto the bio-chip allowing for diagnosis of metastasis by monitoring the time-lapse electrical signals that are recorded by the processor.

Method and system for metastasis diagnosis and prognosis

A method for metastasis diagnosis, including adhering a plurality of Human Umbilical Vein Endothelial Cells (HUVECs) on an array of electrodes patterned on a substrate to cover the array of electrodes by HUVECs, measuring an initial electrical signal from each electrode of the array of electrodes, introducing a metastatic-suspicious sample onto the substrate and measuring a set of time-lapse electrical signals from the array of electrodes. Each electrode has an On/Off two-state, including an On state for an entirely-covered electrode by a HUVEC and an Off state for a partially-covered electrode by a HUVEC. Diagnosing metastasis responsive to detecting a state change from On to Off for at least one electrode of the array of electrodes.
