Innovative researchers from Tianjin University have unveiled a groundbreaking terahertz photoacoustic system that triumphantly overcomes the challenge of water interference. This system enables non-invasive, real-time monitoring of sodium ion concentrations in the blood of both living mice and humans. By seamlessly integrating terahertz spectroscopy with photoacoustic technology, the system detects acoustic signals stimulated by terahertz energy, thereby circumventing the need for traditional physical water removal methods. This advancement opens up a novel path for the utilization of terahertz waves in the biomedical realm. The research team anticipates that this technology could pave the way for detecting a myriad of biomolecules, including ions, sugars, and proteins, with vast potential for clinical applications.
