Chinese researchers develop system for non-invasive monitoring of sodium levels in blood
The device has been tested on laboratory mice and volunteers and has shown high measurement accuracy
A research team from Tianjin University has unveiled a new system that allows real-time, non-invasive monitoring of blood sodium levels. The technology can be used to monitor dehydration, kidney disease and neuroendocrine disorders. This is reported by China Daily, a partner of TV BRICS.
It is noted that the technology is based on terahertz radiation, which is between microwaves and infrared light. It consumes little energy, causes almost no damage to tissue and responds well to changes at the molecular level. However, it was previously difficult to use in medicine because it is strongly absorbed by water and does not pass well through body tissue.
The researchers proposed a solution: a terahertz optoacoustic system that emits waves at frequencies that resonate with sodium ions but exclude signals from water. This allows selective excitation of sodium vibrations and their conversion into ultrasonic signals, which are then recorded by transducers.
This approach provides better penetration through tissues, including muscles and bones, and allows for accurate tracking of sodium levels. It is emphasised that the system can be adapted to analyse other ions, such as potassium and calcium, as well as biomolecules, including sugars, proteins, and enzymes. This expands its potential application in clinical practice.

Ashok MondalNID Director"Signing this Memorandum of Understanding between the National Institute of Design (NID) and TV BRICS marks a pivotal milestone in advancing design diplomacy across the BRICS media space. This moment is especially significant as India hosts the 18th BRICS Summit, following India’s assumption of the BRICS chairship under the visionary leadership of Prime Minister Shri Narendra Modi. The partnership directly embodies his call to elevate Indian design standards through 'Design in India, Design for the World'. Through the global reach and broadcast capabilities of TV BRICS, we are excited to showcase the extraordinary visual storytelling, films, and design research of NID’s Film and Video Communication students to an international audience, while also welcoming and screening film works from BRICS network countries at NID Ahmedabad. This reciprocal exchange strengthens our shared commitment to educational, cultural, and artistic collaboration, fostering sustainable connections among global creative communities. NID Ahmedabad looks forward to leveraging this partnership to deepen cross-cultural dialogue, build international expert networks, and unlock transformative opportunities for filmmakers, researchers, and faculty across member nations" -

So, we have an opportunity to lead by example. We have our development bank, which can demonstrate and develop new ways of financing programmes. We can reduce the risks for private capital to invest in restoration and efforts to combat desertification" -
