    • The present invention provides an apparatus and method for nucleotide or DNA sequencing by monitoring the molecular charge configuration as the DNA moves through a protein that is capable of transcribing the DNA. The apparatus and method provides a nanoscale electrometer that immobilizes the protein. The protein receives the DNA and transcribes the DNA. The nanoscale electrometer is a sensitive device that is capable of sensing and measuring the electronic charge that is released during the transcription process. The apparatus and method of the present invention further provides monitoring means that are attached to the nanoscale electrometer to monitor the electronic charge configuration as the DNA moves through the protein. Once the electronic charge configuration is established, a correlation is computed, using computing means, between the electronic charge configuration and a nucleotide signature of the DNA.

    • A system for scanning and measuring a surface charge of a sample immersed in a conductive medium, such as an aqueous electrolytic solution or a gel, or positioned on a conducting plate. The system has a semiconductor with a probing surface clad in a charge-sensitive layer. The probing surface moves over the sample during scanning while a bias voltage V.sub.BIAS is applied to create a depletion layer in the semiconductor and to induce the system to alter a measurable electrical property. The electrical property is monitored with the aid of a measuring device and the measurement is correlated to the sample's surface charge. In a preferred embodiment the semiconductor is a part of a cantilever structure of the type having a probing tip and the probing surface is located on the apex of the probing tip thereby enabling examination of the topology and surface charge of the sample concurrently.
    • 一种用于扫描和测量浸渍在诸如电解质水溶液或凝胶的导电介质中的样品的表面电荷或定位在导电板上的系统。 该系统具有包含在电荷敏感层中的探测表面的半导体。 探测表面在扫描期间移动到样品上方,同时施加偏置电压VBIAS以在半导体中产生耗尽层并诱导系统改变可测量的电性能。 借助于测量装置监测电气特性,测量与样品的表面电荷相关。 在优选实施例中,半导体是具有探测尖端的类型的悬臂结构的一部分,并且探测表面位于探测尖端的顶点上,从而能够同时检查样品的拓扑和表面电荷。
