This approach is highly efficient, as thousands to hundreds of thousands or even millions of compounds can be generated easily. In this review, we shall briefly discuss the preparation of these chemical microarrays and follow with a more detailed discussion on the various screening methods. Applications of these microarrays to various biological systems will also be described. The approaches that have been employed for preparing microarrays and the methods used to detect activity in different applications are summarized in Table 1. Schematic representations of the generation of planar chemical arrays and bead-arrays are shown in Figure 1. DNA and...

Figure 3.5 Schematic representation of tissue microarray (TMA) fabrication. The tissue cylinders are taken by a sampling needle and embedded into the acceptor block, followed by immunostaining and evaluation of staining intensity.

Faraggi et al. [785] demonstrated fabrication of a CP-LED pixel microarray having the CP sandwiched between ITO and Al, with pixel size as small as 20 /im X 20 /im and claimed extendable to the nm-range. A photo-ablation method employing a 193 nm excimer laser was used. A schematic representation of the procedure is shown...
