🔬 Current methods like trypan blue staining are time-consuming and damage samples.
🌡️ Goossens’ thermal and impedance sensor offers real-time, non-destructive measurements. It correlates sensor output with cell count and viability.
📊 While there are errors, it provides good estimations and potential for improvement.
Introduction:
The article discusses advancements in monitoring cell number and viability, a crucial aspect in biological research and bioprocessing. It highlights an innovative approach developed by researchers at Hasselt University, which utilizes a multi-sensor system to enhance the monitoring of cell health without traditional limitations associated with existing methods.
- Current cell viability assessment methods, such as trypan blue staining and impedance flow cytometry, have limitations including time consumption, sample destruction, and inability to perform continuous monitoring.
- Juul Goossens and colleagues developed a novel multi-sensor that integrates thermal and impedance measurements for real-time tracking of cell health.
- The multi-sensor was tested on yeast cells, showing that sensor output correlates with both cell number and viability.
- Multivariate-regression models derived from the sensor data can estimate cell counts and percentages of viable cells, though with some inherent errors.
- This approach eliminates the need for staining, enables real-time data collection, and minimizes sample damage, making it a promising tool for high-throughput applications.
Conclusion:
The multi-sensor system developed by Goossens and his team represents a significant advancement in cell monitoring technologies, addressing key limitations of traditional methods. Future improvements in sensor fabrication could enhance its accuracy and reliability, potentially leading to broader applications in the fields of research and bioprocessing.
