Methods and apparatus for reacquiring a target on a microscope slide
Methods and apparatus for reacquiring a target on a slide in the field of view of a microscope are provided. The methods and apparatus include a housing, a linear potentiometer positioned in the housing, a contact slidably mounted in the housing and adapted to selectively contact the linear potentiometer, wherein a position of the contact on the linear potentiometer determines the signal output by the linear potentiometer; a linkage having a first end operatively connected to the contact and a second end operatively connected to the slide having the target, wherein the slide is translatable in a first direction; and a receiver adapted to receive a signal output by the linear potentiometer and, using the signal, determine a position of the slide. The linear potentiometer may be a membrane-type linear potentiometer. Aspects also include methods and devices for re-positioning a slide on a stage in a predetermined position.

MICRO FLOW PATH DEVICE, TESTING METHOD USING MICRO FLOW PATH DEVICE, AND TESTING APPARATUS USING MICRO FLOW PATH DEVICE
A testing method using a micro flow path device configured for a test liquid containing a specimen to be brought into contact with a drug therein and for a test on an action of the drug on the specimen includes: preparing the micro flow path device including: a plurality of micro flow paths, first and second openings which are disposed at both ends of each of the plurality of micro flow paths and communicate with an outside, a storage unit which is provided in each of the plurality of micro flow paths and stores the drug, and a gas-permeable membrane covering the first opening; applying a fluid pressure higher than an external pressure to the test liquid through the second opening from a syringe pump connected to the second opening to pressure-feed the test liquid to the storage unit; and observing a target region set in the micro flow path.
Method for embedding a biological sample in a transparent matrix for analysis using single plane illumination microscopy
The invention is directed to method for positioning and aligning a preferably biological sample in the detection area of the objective of a microscope arrangement. According to the invention, the method mentioned above has the following method steps: a sample is introduced into a transparent medium, preferably agarose gel, which is initially liquid; the medium is changed from the liquid state to the solid state, wherein the sample is fixated within the medium, but the transparency of the medium is retained; the solidified medium is positioned in the microscope arrangement in such a way that the sample enclosed therein is situated in the detection area of the objective. Further, a device is proposed for positioning and aligning a preferably biological sample in the detection area of the objective of a microscope arrangement.
