“…[22][23][24] Meanwhile, its inherent properties of the nontoxicity, good biocompability, bionic characteristics and high electron mobility enable the 1D ZnO nanostructure arrays to be suitable for biosensing applications. [25][26][27][28] Moreover, considering the ability of the ZnO electrodes to capture the target molecules and facilitate the transfer of electrons and signals, [ 12,29 ] the 1D ZnO nanostructure arrays would be an ideal candidate for the electrochemical electrodes to realize effi cient transfer of the electrons from reaction sites to outer collector through the assembled "fast tracks". Furthermore, one could utilize the 1D ZnO nanostructure arrays as matrix to make a composite 1D nanostructure electrode of electrochemical active materials.…”

“…The recent advances in research on these different kinds of nanostructures, focusing on their synthesis, surface functionalization, properties, and applications were reviewed in a few publications during the past few years. For example, nanostructured ZnO and gold nanorods, see also in the reviews of Xu's group [55] and Zhao's group [56] in this issue. We just try to outline the typical related nanostructures and their biomedical applications herein.…”

“…A fluorescência dos QDs é uma ferramenta de extrema relevância para se obter bons resultados de sensibilidade e seletividade na atividade do sensor, 137 sendo uma resposta que traduz as propriedades biológicas ou a composição do meio em sinal óptico. 138 Além disso, os QDs, comparados às moléculas orgânicas, apresentam vantagens importantes para o planejamento de marcadores biológicos, dentre elas: grande deslocamento de Stokes, permitindo que a detecção seja alcançada com sinal de baixa intensidade, região extensa de excitação e uma faixa relativamente estreita de emissão, alta estabilidade, resistência ao fenômeno de fotodegradação ou intermitência da fluorescência, tempo de vida de fluorescência longo e biocompatibilidade, que pode ser atingida diante da funcionalização da superfície ou com o uso direto de QDs não-tóxicos. 139 Nesse sentido, a superfície dos QDs atua como receptora para sistemas conjugados com biomoléculas e a resposta óptica consiste em um resultado que serve para monitorar eventos que ocorrem na superfície.…”
