An optical detection and orientation device is provided comprising housing having an excitation light source, an optical element for reflecting the excitation light to an aspherical lens and transmitting light emitted by a fluorophore excited by said excitation light, a focussing lens for focusing the emitted light onto the entry of an optical fiber, which serves as a confocal aperture, and means for accurately moving said housing over a small area in relation to a channel in a microfluidic device. The optical detection and orientation device finds use in identifying the center of the channel and detecting fluorophores in the channel during operations involving fluorescent signals.

The present invention concerns devices, apparatus and methods for transferring liquids. One aspect of the present invention is a device comprising a plate having a plurality of transfer elements. Each of the transfer elements comprises an aperture in the plate where the aperture is capable of being electrically activated. The plate has one of more attaching elements for attaching the plate to a multiwell plate to form a sealed system except for the apertures of the transfer elements. Usually, the device is adapted for sealing attachment to a multiwell plate. In a method in accordance with the present invention a quantity of liquid is disposed to a second side of a plate having a plurality of apertures in the plate. The apertures are capable of being electrically activated. The liquid is present in a closed well except for the apertures in the plate. To simultaneously expel liquid from the apertures, the apertures are electrically activated. Also disclosed are kits comprising a device in accordance with the present invention.

摘要:
A device for simultaneously dispensing a solution containing a sample to a test device and aspirating the sample from the device. In one embodiment the device is hand-held and includes a control mechanism, e.g., button for activating the dispensing and aspiration of the sample. The testing device may take the form of a multi-well plate with a plurality of wells arranged in rows and columns, with the bottom of the wells formed as a photonic crystal biosensor. The device can be configured with dispense and aspirate manifolds and associated dispense and aspirate ports which are positioned in all the wells along a row or column of wells so as to simultaneously aspirate and dispense solution to all the wells in a row or column of the multi-well plate.
