A capacitor having a first electrode made of an electroconductive nano-wire, a dielectric layer partly covering the peripheral face of the first electrode, and a second electrode covering the peripheral face of the dielectric layer. The anti-reflective coating structure can be utilized to form various integrated circuit structures. One of the jaw members is adapted to connect to a source of electrical energy such that the jaw members are capable of conducting energy to tissue held therebetween. The pivot arms react oppositely to being struck from each respective direction of rotation. The probe is configured for placement within a living organism for an extended period of time to provide sufficient yield of biological marker for analysis.
