    • A vibrating tip surface enhanced Raman spectroscopy (SERS) apparatus, system and method employ a nano-needle configured to vibrate. The apparatus includes the nano-needle with a substantially sharp tip at a free end opposite an end attached to a substrate. The tip is configured to adsorb an analyte. The apparatus further includes a vibration source configured to provide an alternating current (AC) electric field that induces a vibration of the free end and the tip of the nano-needle. Vibration of the nano-needle under the influence of the AC electric field facilitates detection of a Raman scattering signal from the analyte adsorbed on the nano-needle tip. The system further includes a synchronous detector configured to be gated cooperatively with the vibration of the nano-needle. The method includes inducing the vibration, illuminating the vibrating tip to produce a Raman signal, and detecting the Raman signal using the detector.
    • 振动尖端表面增强拉曼光谱(SERS)装置,系统和方法采用配置为振动的纳米针。 该装置包括在与连接到基底的端相对的自由端处具有基本尖锐的尖端的纳米针。 尖端构造成吸附分析物。 该装置还包括一个被配置为提供交流(AC)电场的振动源,其引起自由端和纳米针的尖端的振动。 在AC电场的影响下,纳米针的振动有助于检测吸附在纳米针尖上的分析物的拉曼散射信号。 该系统还包括配置为与纳米针的振动协同地选通的同步检测器。 该方法包括引起振动,照亮振动尖端以产生拉曼信号,并使用检测器检测拉曼信号。
