Grasp one end of a dust-free 22 mm X 40 mm microscope glass coverslip with forceps. Lower one end near the cDNA probe until it touches the surface outside the printed area and slowly lower the opposite end of the coverslip onto the slide. The solution will spread across the entire print area beneath the coverslip. Use a yellow tip to carefully adjust the position of the coverslip over the printed area. Large air bubbles can be moved away from the hybridization area by a gentle tapping on the coverslip with a yellow tip. Small air bubbles will be released during hybridization. 

There are several ways in which to apply the bleach. One is to dip a piece of cotton into the bleach and squeeze until it is almost dry. Beginning at the top, so the bleach will run down over the area to be reduced, lightly wipe the cotton over the area for 2 or 3 seconds. Do not use friction, which could abrade the wet print. Instead, let the chemical action do the work. If you have the correct dilution of bleach it should take several applications to achieve the results you want. However, if the print is exceptionally dense in the area being worked on you can strengthen the working solution by adding more ferricyanide. 

The first half of this chapter focuses on thermal imaging, describing the technique and the strenuous requirements of suitable laser-printable materials. We illustrate the latter with polyaniline composites specifically tailored for high-resolution printing over large areas with moderate throughput. Their use in active matrix backplane circuits for large, mechanically flexible sheets of electronic paper is then described. 

Galvanostatic measurements on the C-MEMS array in a half-cell with lithium as both the counter and reference electrode [32] show a large irreversible capacity loss on first discharge followed by good cycling properties consistent with the behavior of conventional bulk coke electrodes. The lithium capacity normalized to the foot print area of the electrode array is 0.125 mAhcm". This value is nearly twice that of an unpattemed pyrolyzed film of SU-8 photoresist [32], The higher capacity is due to the greater active volume, contributed by the carbon posts over the footprint area (Fig. 2.10). 

Screen-printing is a commonly used industrial technique for fast and inexpensive deposition of films over large areas. The principle of screen-printing is shown in Fig. 11.2. 

Ink adhesion n. The tendency of printing ink to stick to the printed surface and not smear or rub off. An informal test of ink adhesion consists of pressing pressure-sensitive tape over the printed area, waiting a few minutes, then stripping it off and observing the a real fraction of ink coming away on the tape.
