Round 1
Reviewer 1 Report
- In Abstract, the term "higher interaction" sounds strange, better use "stronger interaction".
- Probably the introduction can be improved. Till the measurements and results are described, it isn't clear what kind of optical resonances are going to be studied. The term "Fabry-Pérot interferometry" makes an impression that there should be some very sharp optical resonances, but basically it is just thin film interference observed in reflectance.
- I suggest showing the formula used for calculating the porosity by Bruggeman theory (in subsection "Characterization of TiO2 films").
- I suspect there are many papers devoted to the studies of porosity and refractive index of TiO2 thin films. Perhaps the results of this work could be compared to literature data.
- It is stated that the refractive index and the thickness of the porous films were also estimated by the Transfer Matrix Method, but I cannot find such data in the results. Instead, profilometry was used.

Reviewer 2 Report
The manuscript describes TiO2 mesoporous films for the development of optical detection layers.
The manuscript does not present results on applicability of the device as a sensor. There is only one indication that additional work is needed to demonstrate biosensor application.
Authors can provide results on application as a sensor. Furthermore, I suggest improving the quality of the figures, especially those that contain photographs of the surfaces of the devices.
