L'objectif de ce mémoire de thèse est de présenter une nouvelle méthode de synthèse des polymères à empreintes moléculaires, permettant le contrôle de la formation de l'empreinte et la formation du réseau polymère au plus proche de la cible, dans le but d'améliorer leurs capacités. Pour atteindre cet objectif, nous avons choisi d'utiliser la polymérisation radicalaire contrôlée pour la formation du réseau, et le procédé de polymérisation par précipitation pour le contrôle de la morphologie des particules contenant les empreintes. / The objectif of this thesis was to find another method for the preparation of imprinting polymers allowing the control of the formation of the recognition sites, as well as the enhancement of their capacities. We think that beginning the polymer network near the template will permit to increase the recognition. In this purpose, we have used atom transfer radical polymerization and precipitation polymerization for the control of particle's morphologies.

Devido a sua natureza, possui diversas aplicações cosmológicas. Neste trabalho, o estudo de tais espinores é realizado sob universo de Friedmann-Robertson-Walker plano, homogênio e isotrópico. À luz da Teoria Quântica de Campos em Espaços-Tempo Curvos, com as transformações de Bogoliubov, obteve-se a densidade de partículas criadas em uma métrica modelo de regime assintóticamente plano no passado e no futuro, permitindo-se comparar com soluções exatas presentes na literatura para produção de partículas escalares e férmions de Dirac. Discute- se, também, a compatibilidade do fenômeno de criação de partículas provenientes da Teoria Quântica de Campos em Espaço Curvos com os estudos de Prigogine para descrição deste fenômeno à escala cosmológica, considerando-se um universo termodinamicamente aberto. / The ELKO spinor field associated with spin 1/2 particles and mass dimension 1, con- structed on a complete set of dual helicity eigenspinors of the charge conjugation operator, is a candidate for describing dark matter. Due to its nature, it has several cosmological applications. In this work, the study of such spinors is performed under a homogenous and isotropic Friedmann-Robertson-Walker universe. In the light of the Quantum Field Theory in Curved Space-Time, with the Bogoliubov transformations, we obtained the density of particles created in a model of asymptotically plane metric in the past and in the future, allowing to compare with exact solutions present in the literature for the production of scalar particles and Dirac fermions. It is also discussed the compatibility of the phenomenon of particle creation from the Quantum Field Theory in Curved Space with the studies of Prigogine to describe this phenomenon at the cosmological scale, considering a thermodynamically open universe.
