An anti-cancer agent includes Au purinyl, indolyl, or azaindolyl analogues encapsulated in sterically hindered phosphine ligands. The pilot switch circuitry grounds the hot node prior to, during, and after the cantilever contact and terminal contact of the MEMS come into contact with one another. The supply regulation circuit also includes an adjustment circuit controlled by the control circuit and configured to adjust the regulated voltage according to the reference voltage. The enclosure also defines an internal cavity, and the internal cavity contains a fluid for insulating the at least one transducer from a downhole environment.
