13. Desenvolvimento das barras imunosorventes de agitação e avaliação das técnicas extração sortiva em barra de agitação, microextração em sorvente empacotado e cromatografia líquida para análise de antidepressivos em amostras de plasma / Development of immunosorbent stir bars and evaluation of stir bar sorptive extraction, microextraction by packed sorbent and liquid chromatography for the analysis of antidepressants in plasma samples
In this work, polyclonal and monoclonal anti-fluoxetine antibodies were developed in rabbits and mice by immunization with fluoxetine-bovine albumin conjugate, respectively. The developed antibodies were characterized on the basis of the specificity against the drug by ELISA (enzyme linked immunosorbent assay) and, subsequently they were purified by labmade

14. Synthesis, characterization and application adsorptive of a new sililante agent immobilized on silica gel by different routes. / Síntese, caracterização e aplicação adsortiva de um novo agente sililante imobilizado na sílica gel por rotas distintas
The reaction between 3-aminopropyltriethoxysilane (AMPTS) with thioglycolic acid (TGA) resulted in a new sililante agent, AMPTGA. This matrix has nitrogen, oxygen and sulfur as basic centers, that have ability to adsorb metallic cations in solution. Immobilization of AMPTGA onto silica gel surface was developed by using conventional heterogeneous method, usi

15. Detecção condutométrica sem contato: uma nova ferramenta para monitoramento de interações biomoleculares em microssistemas analíticos / Contactless conductivity detection: a new tool for monitoring biomolecular interactions on analytical microsystems
The study reported in this thesis shows the application of a capacitively coupled contactless conductivity detection (C4D) for monitoring biomolecular interactions on analytical microsystems. Initially, the analytical performance of the microsystems fabricated in glass, poly(dimethylsiloxane) (PDMS) and polyester-toner (PT) was investigated in order to choos

16. Estudo da labilidade de Cu(II), Cd(II), Mn(II) e Ni(II) em substâncias húmicas aquáticas utilizando-se membranas celulósicas organomodificadas
In this work commercial filters papers were organomodified with tetraethylorthosilicate (TEOS) and 3-aminopropyltriethoxysilane (3-APTS), aiming at the development of a new analytical procedure for in-situ speciation of labile and inert metal species in aquatic systems. Parameters that exert influence on the metal lability such as pH, chelating time, concent

17. Filmes híbridos orgânico-inorgânicos a partir de óleo de soja funcionalizado
Organic-inorganic hybrids materials can be prepared by the sol-gel process and have applications in biomaterials, catalysis, optics, membranes, chromatography, electrochemistry and coatings. Vegetable oils can be used as organic component for the preparation of these materials and, as they are biodegradable and obtained from natural and renewable sources, th

19. ImobilizaÃÃo de invertase em cinzas de carvÃo sinterizadas para hidrolise de sacarose: propriedades e aplicaÃÃo em biorreatores
Ceramic sinterized proceeding from coal fly ashes was used as a support for immobilization of invertase. The attainment of an insoluble support with chemical physical properties to bind invertase into sinterized coal fly ashes is an alternative to decrease environmental pollution with the storage and dissemination through thermal power plants. Of point view,

20. Europium incorporated in silica matrix obtained by sol-gel: luminescent materials
In this work we report some aspects of the chemistry involved in the preparation of modified silicon oxide by the sol-gel process. Europium III compounds were used as luminescent probe. An organic-inorganic hybrid was obtained by hydrolysis of tetraethylorthosilicate (TEOS) and 3-aminopropyltriethoxysilane (APTS). The Eu III compounds were added in different

21. A new method for straightening DNA molecules for optical restriction mapping.
We have developed an improved method of straightening DNA molecules for use in optical restriction mapping. The DNA was straightened on 3-aminopropyltriethoxysilane-coated glass slides using surface tension generated by a moving meniscus. In our method the meniscus motion was controlled mechanically, which provides advantages of speed and uniformity of the s
