This chapter presents the main physicochemical and functional mechanisms substantiating
the understanding and proper modelling of the process of obtaining composite materials with functional oriented structure. These mechanisms were substantiated on the theoretical
and experimental data obtained by the team of authors and their collaborators inside applicative projects for the sensitising and detection of biochemical structure and for the separation of organic pollutants in contaminated waters. The chapter proposes a new analytical method with invariant metrics for sensitization and
biochemical monitoring, based on using magnetically stimulable functionalized
nanostructures, able to prelevate a great number of biochemical analytes, undifferentiatedly and undestructively. Biochemical invariance sensitization-detection is provided by imposing analytical and practical constraints at the level of analytical acquisition and
processing systems, according to the configuration of the magnetic field of the discriminator, molecular weight, specific biochemical fluorescence spectrum. We have presented the analytical structure and the elements that model the process for obtaining
magnetically stimulated functionalised composites, orientated towards the detection and undestructive biological reticulation. The second part of this chapter presents the modelling and the obtaining of new polyvalently functionalized types of materials oriented to the reticulation, encapsulation and separation of organic pollutants in contaminated waters. The obtained material has a strong, biodegradable character, being modelled morphostructurally and morphofunctionally, so as to separate by reticulation a large number of organic pollutants, toxins and microorganisms. The chapter describes the main physicochemical mechanisms that model the conditions of separation, degradation and encapsulation of pollutants.
