    摘要: A resonant armature system (109, 114, 116) for generating a vibrating motion in response to an alternating excitation force includes at least two planar suspension members (109), substantially parallel to each other and separated by a distance. The planar suspension member (109) includes a plurality of independent planar spring members (112) arranged regularly about a central planar region (110) within a planar perimeter region (108). The resonant armature system (109, 114, 116) further includes at least one movable mass (114) positioned between and coupled to the at least two planar suspension members (109) for resonating with the at least two planar suspension members (109) at a fundamental mode resonant frequency.

    摘要: An electrode for detecting interactions between members of a binding pair, which electrode has been modified by formation of a non-conductive self-assembled monolayer, and a method of detecting biomolecules, such as nucleic acids or other targets, including receptors, ligands, antigens or antibodies, utilizing such an electrode. When contacted with a target nucleic acid, an oligonucleotide probe coupled to the self-assembled monolayer reacts with the target nucleic acid form a hybridized nucleic acid on the modified electrode surface. The hybridized nucleic acid is reacted with a transition metal complex capable of oxidizing a preselected base in the hybridized nucleic acid in an oxidation-reduction reaction, the oxidation-reduction reaction is detected, and the presence or absence of the nucleic acid is determined from the detected oxidation-reduction reaction.
