In this editorial, we comment on the recent article by Fei exploring the field of near-infrared spectroscopy (NIRS) research in schizophrenia from a bibliometrics perspective. In recent years, NIRS has shown unique advantages in the auxiliary diagnosis of schizophrenia, and the introduction of bibliometrics has provided a macro perspective for research in this field. Despite the opportunities brought about by these technological developments, remaining challenges require multidisciplinary approach to devise a reliable and accurate diagnosis system for schizophrenia.

Article Synopsis
- - Laser-based mid-IR photothermal spectroscopy (PTS) is a rapid and sensitive analytical method that utilizes advanced laser technology to capture the absorption characteristics of various materials, such as liquids or solids.
- - This study utilizes an external cavity quantum cascade laser (EC-QCL) to analyze a thin film of polymethyl methacrylate (PMMA) on a silicon nitride micro-ring resonator, demonstrating its effectiveness in creating an on-chip photothermal sensor.
- - The research highlights the optimal alignment and focusing techniques for the laser setup, showing that PTS can lead to compact, efficient sensors suitable for real-time monitoring in industrial applications.

Background: Mixed venous saturation (SvO2) is considered the gold standard to assess the adequacy of tissue oxygen delivery (DO2) in shock states. However, SvO2 monitoring is challenging as it requires an invasive catheter and frequent blood sampling. Non-invasive methods, including near-infrared spectroscopy, have demonstrated low sensitivity to tissue dysoxia.
