High-Sensitivity SPR Sensor Based on the Theory of the Solution of Inventive Problems
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThe manuscript entitled High Sensitivity SPR Sensor Based on TRIZ Theory, by Cui-lan Zhu and co-workers, presents a SPR Sensor Based on TRIZ Theory. I think that the work is very innovative. Here are my comments.
1. In the introduction part, more background information about the TRIZ theory should be added.
2. What is the performance improvement for the SPR sensor when the TRIZ theory is introduced
3. The description of optimizing SPR sensors using TRIZ theory is innovative, but the detailed description of the specific application of TRIZ in the method is not enough and may be difficult for non-expert readers to understand.

Reviewer 2 Report
Comments and Suggestions for AuthorsReferee Report on the paper “High sensitivity SPR sensor based on TRIZ theory” by C.-I. Zhu et al. submitted to Photonics.
In the paper, the authors briefly discuss the SPR fiber sensor based on single-mode optical fiber covered by gold (nano)layer, and gold nanoparticles layer. Similar sensors are quite well known, see e.g. papers “Optimization of gold-nanoparticle-based optical fibre surface plasmon resonance (SPR)-based sensors” by M.H. Tu, T. Sun, K.T.V. Grattan, Sensors Actuators., 2012 B164, 43, or “Ultra-high sensitivity SPR fiber sensor based on multilayer nanoparticle and Au film coupling enhancement”, Feng Xia, Hang Song, et al., Measurement, 164, (2020) 108083 (by the way, these authors work in the same University as the authors of the paper under review), or many others. There will be nothing to discuss provided the paper is limited to the theory only. But the good point of the paper is that the authors present an experimental realization and brief characterization of such a sensor (without its detailed comparison with analogues) – but, in my opinion, this still does not warrant the publication in Photonics. For example, I was not able to understand what exactly gold nanoparticles are used (what does “a gold nanoparticle dispersion” in line 308 in reality mean? By the way, what does the sentence “the functional analysis by simulation using the villain method” at line 245 mean?).
Instead of this necessary for the Photonics discussion, the authors at length present the use of “TRIZ theory” (by the way, such an abbreviation in the title is inacceptable), which is the Russian abbreviation of the “Theory of solution of the invention (or inventors’) problems”. The present reviewer does not feel himself competent to judge how interesting this discussion is in general and for some other journals. But it is not relevant for the Photonics journal. I recommend rejection.
