✨📄 Reimagining the lateral flow test with luminescent nanomaterials
Excited to share our new paper:
Paper-based immunoassay enabled by silver clusters embedded within zeolites
Lateral flow assays have transformed point-of-care diagnostics, but conventional colorimetric formats often struggle with sensitivity and quantitative analysis.
In our latest work, we introduce a new approach based on silver cluster–zeolite composites that simultaneously perform molecular recognition and luminescent signal generation—eliminating the need for conventional conjugate pads.
Congratulations Cecilia García Guzmán and all the Team!
🔬 Key highlights:
✅ Antibody-functionalized luminescent probes integrated directly into paper-based devices
✅ Sensitive and quantitative detection of human IgG
✅ Robust performance in the presence of interfering proteins and human serum
✅ Smartphone-based fluorescence readout with custom image analysis algorithms
✅ Simplified architecture for low-cost, scalable point-of-care diagnostics
By combining advanced luminescent nanomaterials, paper microfluidics, and smartphone analytics, this work demonstrates a promising route toward the next generation of portable, user-friendly biosensors for decentralized healthcare.
