The chain ends of the star polymers can be functionalized. So it is possible to link these sites and form networks or gels of stars. Depending on the chemical nature of the chain end, the crosslinking can be permanent or stimuli-switchable. Patrick-ios et al. [105] have prepared crosslinked double hydrophilic star copolymers made from methacrylic acid (MAA) and poly(ethyleneglycol methacrylate) (PEGMA). Meyer et al. [106] synthesized photocrosslinkable PMAA stars, which could serve as well-defined model polyelectrolyte networks. The polyelectrolyte stars can also be used as template for some nanomaterials. Want et al. [107] prepared strong anionic polyelectrolyte stars by sulfonation of the PS stars. They were used as the template for the preparation of conducting polyaniline.

An alternative to in situ polymerization involves direct intercalation of macromolecules into layered structures. Silicates are most often used. The insertion of polymer molecules into layered host lattices is of interest from different points of view. First, this insertion process leads to the construction of organic-inorganic polylayered composites. Second, the intercalation physical chemistry by itself and the role intercalation plays in the gain of electronic conductivity are of interest. This becomes important in the construction of reversible electrodes " or when improving the physicomechanical properties of nylon-layered silicate nanocomposites, hybrid epoxide clay composites," and nanomaterials based on hectorite and polyaniline, polythiophene or polypyrrole. ... 

After the immunological event has taken part, it has to be transduced. As was commented in Section 9.1, a sensor consists of two parts recognition and transduction, usually very selective and sensitive. Both are commonly combined in a single device (except in the case of the so-called magnetoimmunosensors or automatized devices) with complicated architectures. Surface is carefully engineered to get better performance and the best analytical features. Therefore, the primary transducer (e.g., a SPE) is converted into a different one that could be called the secondary transducer. Connection with the primary transducer is often achieved with the help of conductive nanomaterials (e.g., CNTs, molecular wires, etc.) or polymers (e.g., polyaniline). In this section that is devoted to the important transduction of the immunological events, the main electrode materials and types, the approaches for the detection, the use of labels and label-free formats, as well as the main techniques are summarized.
