The present invention relates to a method for manufacturing a probe for detecting surface signals or chemical signals through a long and slender rod-shaped nano structure such as tungsten nanowire, carbon nanotube, boron nanotube, etc. A fishing accessory, such as a fish hook retainer, can be attached to a fishing rod using a device with a shape suitable to be clamped between the mounting flange of a fishing reel and a fishing rod andor reel clamp of the fishing rod. A bias generator circuit generates a bias voltage for application to the pair of cascode transistors in the folded cascode architecture. Under the invention, while such a web page is being navigated by such computers, software observes one of them, and looks for the event of scrolling. One seed crystal is put in each of the crucibles to grow the nitride single crystal on the seed crystal. The RF communication mediums facilitate communication of RF signals.
