In a glimmer of hope for affordable diagnostics, researchers at Bengaluru's Raman Research Institute (RRI) have created a low-cost electro-fluidic micropore device for initial screening of Sickle Cell Disease (SCD). The development has the potential to revolutionize early detection and mass screening of blood disorders, particularly in rural and underserved regions.

Key Highlights

Low-Cost, High-Resolution Device Created

• RRI researchers developed an electro-fluidic micropore device that quantifies whole-cell stiffness in red blood cells (RBCs).

• The device facilitates high-throughput and high-resolution screening, which is essential to detect abnormalities concerning SCD.

Collaborative Validation on Real Samples

• Development of the device by Gautam Soni, S. Kaushik, and A. Mishra at RRI.

• Testing done in collaboration with St. Johns Medical College Hospital, comparing SCD patient blood and healthy blood.

Accuracy in Differentiating SCD from Healthy RBCs

• The device employs flight-time analysis to monitor changes in RBC stiffness, a primary marker of disease state.

• Treated cells with Latrunculin A validated the relationship between cell flight time and stiffness.

Broader Applications Beyond SCD

• Can be applied to tumor detection, veterinary medicine, and hydrogel research for drug delivery.

• Potential to transform initial blood diagnostics across a variety of fields.

Suitable for Rural and Mass-Screening Programs

• The device's portability and affordability make it ideal for deployment in resource-poor environments.

• Facilitates early intervention and enhanced disease outcomes, particularly among SCD-affected populations.

This indigenous innovation from RRI highlights India's growing potential in low-cost healthcare technologies. With its emphasis on portability, precision, and affordability, the electro-fluidic micropore device presents a scalable solution for mass screening and early diagnosis of Sickle Cell Disease and potentially other health conditions. The RRI team's achievement paves the way for wider deployment and greater research partnerships in the diagnostic sector.
