    • An electrically driven device (10) for surface enhanced Raman spectroscopy includes a first electrode (16), a substrate (12) positioned proximate to the first electrode (16), a plurality of cone shaped protrusions (12') formed integrally with or on a substrate surface (S), a Raman signal-enhancing material (14) coated on each protrusion (12'), and a second electrode (18) positioned relative to the first electrode (16) at a predetermined distance, D. Each of the protrusions (12') has a tip (22) with a radius of curvature, r, ranging from about 0.1 nm to about 100 nm. The second electrode (18) is positioned relative to the first electrode (16) such that the electrodes (16, 18) together produce an electric field (EF) when a voltage bias is applied therebetween. The electric field (EF) has a field distribution that creates a stronger field gradient at a region proximate to the tips (22) than at other portions of the substrate (12).
    • 用于表面增强拉曼光谱的电驱动装置(10)包括第一电极(16),靠近第一电极(16)定位的衬底(12),与该第一电极(16)一体形成或多个形成的多个锥形突起 涂覆在每个突起(12')上的衬底表面(S),拉曼信号增强材料(14)和相对于第一电极(16)以预定距离D定位的第二电极(D)。 突起(12')具有从约0.1nm至约100nm范围内的具有曲率半径r的尖端(22)。 第二电极(18)相对于第一电极(16)定位,使得当施加电压时,电极(16,18)一起产生电场(EF)。 电场(EF)具有在靠近尖端(22)的区域处比在衬底(12)的其它部分处产生更强的场梯度的场分布。
