Bifunctional biolabels with magnetic and luminescent properties are highly desirable for in vitro and in vivo bioimaging. There are several strategies to use NPs to comprise such biolabels, such as core/shell NPs, for example, the magnetic cores of iron oxide doped with cobalt and neodymium and luminescent shells of Gd203 Eu (Dosev et al., 2005,2007).

The LSCEs represent a new class of macromolecular systems distinguished by macroscopically uniform anisotropy. The concept of LSCE can be furthermore extended to other synthesis routes and to the densely crosslinked systems. Macroscopic uniaxially oriented films can be formed by mechanical force, alignment surface [30], magnetic and electric fields [31], polarized light [32], etc., and then crosslinked to form an anisotropic network (LC network is abbreviated as LCN) if the mixture components contain polymerizable or crosslink-able bifunctional monomers (Figure 9.13). Alternatively, amorphous or liquid crystalline side-group and/or main-chain polymers incorporating additional... 

Europium ions are photoluminescent rare earth ions that exhibit a high yield of luminescence in the visible light region. Several Eu -containing complexes were electrospun with synthetic polymers such as PVA [6], PMMA [48], PAN [49, 50], and PVP [51-53], in some cases in the presence of other functional inorganic particles. As an example. Fig. 5 shows bifunctional magnetic-photoluminescent nanofibers based on Fc203 nanoparticles and an europium complex [52].
