“…Um dos grandes desafios para a construção de biossensores mais sensíveis, robustos e de maior confiabilidade é a imobilização das biomoléculas sobre superfícies condutoras, em sua forma estável e com a manutenção de suas propriedades biológicas de reconhecimento 100 . Os procedimentos de adsorção, ligação cruzada, ligação covalente e encapsulamento em géis ou membranas são os métodos de imobilização de biomoléculas mais empregados 101,102 . Contudo, estes processos produzem uma superfície altamente desorganizada, com as biomoléculas orientadas randomicamente, provocando mudanças conformacionais que afetam a atividade funcional do componente bioativo 103 .…”

“…Examples include the quality of a pure NTA SAM 27 , conjugation chemistry for grafting NTA headgroups onto substrate surfaces 29 and the sequential surface activation step 28 . When combined with additional results from immunoassay 24,27 and molecular recognition experiments 32 , the bioactivity and orientation of proteins at solid/ liquid interfaces can be deduced. Surface structural information and NTA headgroup surface concentrations have not been addressed and related to protein specific immobilization and dissociation in flow assay conditions.…”
