New method for detecting viral infections in cells UPSC NOTE

 One Health Approach: 

  • Monitoring animal, plant, and human health together is crucial to prevent pandemics like COVID-19.

New Light-Based Detection Method: 

  • Researchers developed a method using light and basic physics principles to identify virus-infected cells.

How it Works:

  • Viral infection changes the shape and size of cells.

  • Shining light on the cells reveals these changes through diffraction patterns (light patterns).

  • The difference in patterns between healthy and infected cells acts as a "fingerprint" for viral infection.

Advantages of the New Method:

  • Faster: Takes only 2 hours compared to 40 hours for traditional methods.

  • Cheaper: Costs about 1/10th compared to traditional methods using chemical reagents.

  • Easier to use: Requires only light and a microscope.

  • More widely accessible: Benefits low- and middle-income countries with limited resources.


Potential Applications:

  • Early detection of viral infections in animals, including livestock and pets.

  • Selecting healthy animals for breeding.

  • Monitoring outbreaks like bird flu.

Future Considerations:

  • The method is new and real-world testing is needed.

  • It's not specific to a particular virus but detects viral infections in general.
