“…The technique of consecutive adsorption of anionic and cationic layers has been well documented by, for example, Decher et al [2][3][4] who reported on various systems involving these electrostatic interactions. Films with alternating layers of the anion cobalt phthalocyanine tetrasulphonate and cationic polydimethyldiallylammonium chloride prepared by electrostatic layer-by-layer adsorption were reported by Lvov et al [5]. Heteropolyanions (HPAs) are still a rapidly growing class of compounds with various applications ranging from catalysis to analytical chemistry and medicine [6,7], their use as the anionic moiety in self-assembled multilayers has been studied extensively.…”

“…Uma vez controlados os parâmetros de deposição, diversas estruturas podem ser idealizadas através da deposição de multicamadas de vários compostos, 1,4 como biomoléculas, complexos de coordenação, polímeros sintéticos e condutores, cristais líquidos poliméricos, entre outros. Em alternativa à técnica LB, Decher 20,25,28,[42][43][44] imobilizadas em filmes finos LbL apresentam processos redox bem definidos, elevada estabilidade química e um arranjo geométrico quadrado planar, onde os grupos pirrois, no plano equatorial, apresentam-se inertes em relação às reações de substituição.…”

“…7,8 A automontagem ganhou atenção especial devido a vantagens tais como fácil manipulação, baixo custo operacional, reprodutibilidade, versatilidade dos materiais utilizados e elevado controle da arquitetura molecular. 2,[9][10][11][12][13][14][15][16][17][18][19][20] Diversos materiais têm sido empregados na técnica LbL visando construção de filmes nanoestruturados, como metaloftalocianinas, 1,2,11-31 porfirinas, [32][33][34] polímeros condutores, 1,10 diazo-resinas, 15 nanopartículas metálicas 3,16,35 e moléculas biológicas. 14,16,17 Em especial, compostos de coordenação, quando imobilizados em filmes LbL, apresentam comportamento químico diferenciado quando comparados em solução e no estado sólido, situações nas quais efeitos supramoleculares devem ser levados em consideração.…”

“…As a novel method proposed by Decher and co-workers, layer-bylayer (LBL) adsorption method has been widely used in the assembly of nanoscale films composed of polyelectrolytes, such as proteins, DNA and, etc. It has been proved that LBL method is a promising way especially for the immobilization of biomolecules [15][16][17][18][19]. LBL method, which is based on electrostatic being forced between oppositely charged polyelectrolytes has been utilized on the immobilization of enzymes and construction of a biosensing system [20,21].…”
