Two-dimensional inorganic networks can shown intracrystalline reactivity, i.e., simple ions, large species as Keggin ions, organic species, coordination compounds or organometallics can be incorporated in the interlayer region. The host-guest interaction usually causes changes in their chemical, catalytic, electronic and optical properties. The isolation of materials with interesting properties and making use of soft chemistry routes have given rise the possibility of industrial and technological applications of these compounds. We have been using several synthetic approaches to intercalate porphyrins and phthalocyanines into inorganic materials: smectite clays, layered double hydroxides and layered niobates. The isolated materials have been characterized by elemental and thermal analysis, X-ray diffraction, surface area measurements, scanning electronic microscopy, electronic and resonance Raman spectroscopies and EPR. The degree of layer stacking and the charge density of the matrices as well their acid-base nature were considered in our studies on the interaction between the macrocycles and inorganic hosts.

Os autores apresentam a possibilidade do uso da videolaparoscopia em ratos. Foram utilizados 10 ratos Wistar. Empregaram uma óptica de 3mm, 30 graus, usada em artroscopia. Obtiveram boa visibilização dos órgãos da cavidade peritoneal. A introdução de agulhas especiais e instrumentos delicados permitiram realizar os procedimentos operatórios. O modelo experimental proposto tornou-se viável, em ratos.
