    Abstract: A method, apparatus and probe for examining tissue for the presence of target cells, particularly cancerous cells, by subjecting the tissue to be examined to a contrast agent containing small particles of a physical element conjugated with a biological carrier selectively bindable to the target cells. Energy pulses are applied to the examined tissue. The changes in impedance and/or optical characteristics of the examined tissue produced by the applied energy pulses are detected and utilized for determining the presence of the target cells in the examined tissue. In a described preferred embodiment, the applied energy pulses include laser pulses, and the physical element conjugated with a biological carrier is a light-sensitive semiconductor having an impedance which substantially decreases in the presence of light. The same probe used for detecting the targeted cells may also be used for destroying the cells so targeted.

    Abstract: The present invention relates to a device for tissue-characterization, designed for effective sensor-to-tissue contact. The device includes an element, having a rigid surface of a linear cross-section, on which at least one sensor is arranged, and a mechanism for applying a force to a soft tissue, the line of force being at an acute angle with the rigid surface, for stretching or stretching and pushing the soft tissue against the rigid surface, thus achieving effective contact between the tissue and the at least one sensor. In consequence, the accuracy of the sensing is improved. In accordance with another embodiment, a plurality of sensors is employed, arranged along a curved element, for providing three-dimensional information regarding the tissue, for example, by small-scale computerized tomography.
