A team of researchers at UCLA has developed a new sensor that can track important body molecules, called metabolites, in real-time. These molecules play a key role in keeping our bodies functioning properly. Unlike older methods that require lab tests and give only short-term results, this new sensor can monitor multiple metabolites continuously.
Why Metabolites Matter
Metabolites help produce energy, control cell activity, and keep our body balanced. Tracking them can help doctors understand diseases, check overall health, and see how treatments are working. However, current methods are limited. Most tests only provide single-time results, and only a few sensors can continuously track metabolites, mostly focusing on blood sugar.
How the TMR Sensor Works
Researchers from the California NanoSystems Institute at UCLA have created a new technology called Tandem Metabolic Reaction-based Sensors (TMR Sensors). This sensor works by using natural body processes to track different metabolites at once.
- Tiny Carbon Nanotube Electrodes: The sensor is built using tiny cylinders called carbon nanotubes, which act as small biochemical labs.
- Enzymatic Reactions: These electrodes use enzymes and helper molecules to detect and measure metabolites.
- Accurate Detection: The sensors create an electrical current when detecting metabolites, ensuring real-time and reliable tracking.
- Preventing False Signals: Other enzymes help neutralize interfering molecules, making the results more accurate.
Future of Health Monitoring
This new sensor could change how doctors monitor diseases and treatments. It allows continuous tracking of multiple metabolites, helping improve patient care. With further development, this technology could lead to more advanced and non-invasive health monitoring tools.
