“…Suspensões luminescentes de pontos quânticos coloidais também já foram inseridas visando a aplicações em sensoriamento de temperatura. 101,102 Outra fonte de luz foi demonstrada em fibra optofluídica, através de efeitos ópticos não lineares em água introduzida no núcleo oco de uma fibra de bandgap fotônico. 93 Esta fibra era excitada com pulsos de femtossegundos em 980 nm e efeitos ópticos não lineares na água geravam um enorme alargamento espectral, gerando uma fonte de espectro supercontínuo se estendendo por uma faixa de comprimentos de onda de 600 nm a 1200 nm.…”

“…Além da funcionalização com antígenos e com nanopartículas metálicas, descritas acima, um sensor de temperatura já foi descrito em que pontos quânticos coloidais eram fixados eletrostaticamente com uma técnica layer by layer. 101 Mais recentemente, microflocos de óxido de grafeno em suspensão foram inseridos em fibras de cristal fotônico. [109][110][111][112] Após secagem, o material permanecia nas fibras, recobrindo o interior dos canais.…”

Fiber optic sensors have been developed taking advantage on the synergy between the properties of nanostructured materials and the ones that characterize an optical fiber. The mechanical properties of optical fiber introduce some restrictions to the techniques used for the deposition of materials. As an alternative to the classical deposition procedures, wet coating techniques have been successfully applied in these cases. The current chapter put emphasis on materials that can be incorporated using wet coating techniques. The first one presented is the multilayer based nanostructures: among the different alternatives, we have focused on materials prepared with the Layer-by-Layer technique. Another type of products used for the fabrication of optical fiber sensors is sol-gel matrices, which are made of silica, so that its optical properties are similar to the ones of an optical fiber. The other two described type of products have focused the attention of many researchers in the recent years. Firstly, materials with an enhanced selectivity are presented: the molecularly imprinted polymers (MIPs). Finally, sensors based on metallic nanolayers and particles are presented. All these materials and techniques have acquired a great importance in the field of optical fiber sensors due to their versatility and the good features that offer.

“…As an example, CdTe quantum dots of various sizes have been embedded in polymeric films using the Layer-by-Layer technique in order to obtain temperature sensors by means of different optical fiber configuration schemes. In [72], the structures have been fabricated onto MMF tapered ends while in [73] and [74] the structures have been fabricated in the inner part of HCFs and in the holes of MOFs respectively (see Fig. 3), which protects the QD nanofilm from the environment while it is still sensitive to temperature changes reducing considerably the effects of photobleaching.…”

This work comprehends a review of nanostructured materials employed in the fabrication of optical fiber sensors in the last years. The continuous advances in nanofabrication techniques have enabled to manipulate the matter precisely producing well defined nanostructurated coatings or repetitive patterns at nanoscale level. The interactions of light with these nano-organized materials or patterns at the nanoscale level enable to observe interesting phenomena, such as interferometry, fluorescence, absorbance, resonances and many others which can be exploited in the fabrication of sensing devices. A particular case consists of optical fiber sensors, where the light travelling through an optical fiber interacts with the sensitive layer. The properties of the sensitive layer, such as the organization, physical properties, chemical bounds etc. will determine the sensing characteristics of the final device. The utilization of some of the most common nanostructured materials, such as polymers, nanoparticles, metals, metal oxides or biological coatings are reviewed here.
