Move the water molecules and sodium and chloride ions to model how water dissolves salt. Tape the molecules and ions to the paper to represent water dissolving salt. Project the animation Sodium ...

Scientists have pioneered a new way to monitor sodium levels in the blood—without drawing a single drop. By combining terahertz radiation and optoacoustic detection, they created a non-invasive system ...

TIANJIN -- A Chinese research team has developed a novel system to enable non-invasive and dynamic monitoring of blood sodium ...

As the sample absorbs these waves, it vibrates the sodium ions connected to water molecules in the blood, creating ultrasound ...
