Techniques for characterizing a molecule are described herein. In one example, a portion of the molecule is trapped in a nanopore, a variable voltage is applied across the nanopore until the trapped portion of molecule is moved within the nanopore, and the molecule is characterized based on the electrical stimulus required to affect movement of at least a portion of the trapped portion of the molecule within the nanopore.

A method for measuring a neural response to a stimulus. Measurement circuitry is settled prior to a stimulus, by connecting a sense electrode to the measurement circuitry to allow the measurement circuitry to settle towards a bio-electrically defined steady state. Charge is recovered on stimulus electrodes by short circuiting the stimulus electrodes to each other. An electrical stimulus is then applied from the stimulus electrodes to neural tissue, while keeping the sense electrode disconnected from the measurement circuitry. After the stimulus, a delay is imposed during which the stimulus electrodes are open circuited and the sense electrode is disconnected from the measurement circuitry and from the stimulus electrodes. After the delay, a neural response signal present at the sense electrode is measured by connecting the sense electrode to the measurement circuitry.

The object of the present invention is to provide a linear device which is very thin, can be inserted into a desired region of a subject, and minimizes the damage to the subject. The linear device is a linear member, which comprises a base layer extending in the axial directions of the linear member and a plurality of layers formed on the base layer and extending in the axial directions of the linear member. Two or more of said plurality of layers are conductive layers and two or more of said plurality of layers are insulating layers. Each insulating layer is disposed between the conductive layers. When the linear device is embedded in or its front end is inserted into a region of a subject, electric stimuli can be given to the region and the electric resistance of the region can be measured. Because the linear device is very thin, pain or uncomfortable feeling at the region is slight when it is inserted or embedded in a region of the human body or the like.

An evaluation apparatus is taught to nondestructively characterize the electroluminescence behavior of the semiconductor-based or organic small-molecule or polymer-based light-emitting material as the finished light-emitting device functions through electroluminescence. An electrode probe is used to temporarily form a light-emitting device through forming an intimate electrical contact to the surface of the light emitting material. A testing system is provided for applying an electrical stimulus to the electrode probe and temporarily formed device and for measuring the electrical and optical/electroluminescence response to the electrical stimulus. The electrical and optical properties of the light-emitting material can be nondestructively determined from the measured response. Optionally a light stimulus is used to perform the photoluminescence characterization together with the electroluminescence characterization, and both characterizations can be performed at the same sample location or/and at the wafer level.
