A groundbreaking study has demonstrated the potential of optical spectroscopy to assess COVID-19 severity rapidly. By employing Brillouin light scattering (BLS) spectroscopy, researchers have shown that subtle changes in blood plasma viscosity can serve as a valuable biomarker for disease progression.
BLS is a non-invasive technique that analyzes the interaction of light with acoustic waves within a sample. In this case, researchers used it to measure the blood plasma viscosity of COVID-19 patients. They discovered significant differences in viscosity compared to healthy individuals, particularly at elevated temperatures. These changes are believed to be linked to alterations in plasma composition, which can impact blood flow and potentially contribute to severe complications.
The speed and sensitivity of BLS spectroscopy offer significant advantages for patient monitoring. The technique requires only minuscule sample volumes and delivers results in less than a second, making it suitable for real-time assessment of critically ill patients. Moreover, the insights gained from this study could inform the development of targeted therapies and improve our understanding of COVID-19 pathogenesis.
While further research is necessary to translate these findings into clinical practice, the study represents a promising step forward in leveraging optical spectroscopy technologies for disease diagnosis and management. By expanding the application of BLS to other diseases and delving deeper into the underlying biophysical mechanisms, researchers aim to unlock the full potential of this powerful technique.
