The flexibility of the substrate, the ease, and the low costs of fabrication of this DFB-polynter laser offer a very promising way to novel surface-emitting laser devices which take full advantage of the properties of conjugated polymers.

Besides the polymerization techniques discussed above, other polymerization methods have been used for the preparation of surface grafts. Recently, ring-opening metathesis polymerization (ROMP) became popular. This polymerization type will be discussed by Buchmeiser in Chapter 8. Recently, interesting accounts have appeared on solventiess polymerization techniques applying (living) ROMP on surfaces to prepare structured brush surfaces of conjugated polymers [331, 332]. 

When a 7i-conjugated polymer has long alkyl or alkoxy side chains and forms the stacked structure, it tends to be aligned on the surface of substrates (e.g., Pt plate) with the alkyl or alkoxy chains oriented toward the surface of the substrate [95,128,134,135], presumably because of a strong tendency for the alkyl chain to stand upright on the surface of substrates [95,136]. Actually, the PAEs shown in No. 19 in Table 2 are aligned on a Pt plate with the OR chains oriented toward the surface of the Pt plate [95]. A model for the alignment is depicted in Fig. 1. 

Another coupling method, i.e. cross-linking or entrapment in polymeric films, which has been used to create a more permanent nucleic acid surface, is described in some chapters (e.g. conductive electroactive polymers for DNA immobilization and self-assembly DNA-conjugated polymers). One chapter reviews the basic characteristics of the biotin-(strept)avidin system laying the emphasis on nucleic acids apphcations. The biotin-(strept)avidin system can be also used for rapid prototyping to test a large number of protocols and...
