Bottom-Up Synthesis of Mesoporous TiO2 Films for the Development of Optical Sensing Layers

Many optical sensors exploit the interesting properties of porous materials, as they ensure a stronger interaction between light and analyte directly within structure. Most are mainly based on silicon anodized aluminum oxide, showing high sensitivities. However, top-down strategies usually employed to produce those materials might offer limited control over layer, which could affect homogeneity, reducing sensor reproducibility. In this work, we present bottom-up synthesis mesoporous TiO2 Fabry-Pérot displaying sensitivity, low production cost, making platform very promising candidate for development high-performance sensors.
