Addressable arrays

X-ray imagers consist of a phosphor in direct contact with the surface of an array of a-Si H photodiodes. The device is a matrix-addressed array, in which each imaging pixel consists of a photodiode and a TFT [647-649]. These X-ray imagers are very suitable for static and dynamic imaging in medical diagnosis. 

Parallel synthesis is the term loosely applied to the preparation of discrete compounds in the format of a spatially addressable array. It is often used in contrast to "mixture-based" combinatorial synthesis. While it is hue that the term "parallel synthesis" may encompass the preparation of a fully combinatorial multidimensional array of compounds, in practice, it most... 

Microarrays comprise a number of differenf formats, all of which have been adopted in one form or another for commercial use. They can be classified as in situ, ex situ, and electronically active or addressable arrays. A fiberoptic array is an optically addressable, ex situ array (Figure 2.1). While the origin of array-based technology can be traced back several decades (see review by Matson and Rampal, 2003), we examine here the major breakthrough in commercialization that began in the early 1990s. 

The experiments described above demonstrate the ability to deliver soluble analytes to bilayer arrays and to evaluate the ability of these species to prevent surface absorption of proteins. Therefore, we have demonstrated methods of creating spatially addressed arrays of aqueous solutions above phospholipid membranes as well as arrays of phospholipid membranes with unique chemistry in each bilayer.13 These two concepts were carried out in separate assays. To be able to control both surface chemistry and aqueous chemistry... 

FIGURE 6.8. (a) Schematic diagram of bilayer coated PDMS microchannels on a planar glass substrate. The bilayer coats both the glass and polymer surfaces. Protein solutions can then be injected into the channels as indicated by the arrows, (b) Epifluorescence image of a spatially addressed array of eight Egg PC bilayer coated microchannels. The channels are alternately coated with bilayers containing 1 mol% Texas Red and 3 mol% fluorescein labeled lipids.

Functional protein microarrays are useful for direct analysis of biochemical activity (e.g., substrate specificity, Refs. 98 and 99), protein protein interaction (100), or small molecule protein interaction. Proteins of interest are over expressed and applied in pure form on addressable arrays, and assays performed (101).

High density, spatially addressable arrays of planar supported membranes have significant potential in high throughput bioanalytical applications, including screening... 

A small time constant is easy to achieve in a small format array, bnt the RP-dependence on the nnmber of lines qnickly increases the time constant. Typical valnes are Cpp 1-5 pF and Rp 1-10 Q for a conventional metal or Rpp 10-100 kQ for condncting polymers. With conventional metals, the time constant remains small enongh, aronnd 20 [ts, even for arrays where N = 1,000, while condncting polymers conld only address arrays where iV 30 [8]. Therefore, the development of solntion-processed low-resistance condnctors is fnndamental for an all-additive printing process. 

Figure 3.12 shows the glucose sensor in back-detection operation. Six 2 X 2 mm green Alqg OLEDs pixels are lit simultaneously (the use of individually addressable array pixels, any number of which can be lit simultaneously, is unique to OLEDs in its simplicity). As seen in the image, the EL of the OLED pixels is very bright. Consequently, the pixels appear white ... 

In most reported applications, the array concept was apphed in the syntheses, that is, all catalysts were synthesized in spatially addressable arrays of synthesis vials. By the help of synthesis robots, the precursor solutions were dosed to the vials sequentially followed by filtration of the precipitates or by simple drying of the resulting slurries. 

Using this representation model results in a large reduction of the search space if the best combination of space-time mapping and localization must be found. This is indicated in table 1, where the number of domain definitions, dependence vectors and operation definitions that must be considered when iterating over all localization alternatives is compared to what is needed when using the novel representation model. Furthermore, the model can also be used in synthesis environments which do not address array architectures [20].
