A quantum pipette
Curved quantum waveguides are known to bind particles. We show that a number of charged fermions in such a trap can be tuned by an external electrostatic eld; if the latter is slowly increased, the bent duct can serve as a single particle ejector.
متن کاملA mechanical pipette.
An automatic pipette is a very useful equipment for any laboratory carrying out Kahn tests on a large number of sera. A number of devices were tried in a field laboratory which was functioning as a serological laboratory for the CeylonArmy Command during the years 1945 and 1946. A mechanical pipette which can easily be prepared with materials salvaged from a small workshop is described below. T...
متن کاملA multifunctional pipette.
Microfluidics has emerged as a powerful laboratory toolbox for biologists, allowing manipulation and analysis of processes at a cellular and sub-cellular level, through utilization of microfabricated features at size-scales relevant to that of a single cell. In the majority of microfluidic devices, sample processing and analysis occur within closed microchannels, imposing restrictions on sample...
متن کاملSingle-cell electroporation using a multifunctional pipette.
We present here a novel platform combination, using a multifunctional pipette to individually electroporate single-cells and to locally deliver an analyte, while in their culture environment. We demonstrate a method to fabricate low-resistance metallic electrodes into a PDMS pipette, followed by characterization of its effectiveness, benefits and limits in comparison with an external carbon mic...
متن کاملSALSA - A Simple Automatic Lung Segmentation Algorithm
This section contains a concise description of the algorithm, that is divided into 6 steps. After the original image is loaded, a simple thresholding operation is performed to discard data that we are confident that do not belong to the lungs (Figure 1a). After the thresholding, we select the outermost boundary voxels in the axial slices of this pre-segmented volume. The seeds found in Step 1 a...
