Printed Graphene Inks for Scalable Digital Diagnostics: Bridging Printed Electronics and Cloud-Connected Digital Healthcare

Printed graphene-based biosensors are transforming molecular diagnostics by enabling amplification-free, label-free detection of nucleic acid targets in real-time, outside of traditional laboratory settings. This talk introduces a scalable diagnostic platform that uses screen-printed, functionalized graphene inks to deliver highly sensitive and selective results—without the need for PCR, enzymes, or fluorescent labels.

We will explore how functionalized graphene inks, tailored for screen printing, provide the electrical and chemical properties necessary for real-time detection without amplification. The presentation will cover:
Ink formulation and stability challenges
Integration with ssDNA probes and fluidics systems
Signal transduction mechanisms
Use cases in infectious disease, oncology and beyond
Validation, regulatory and commercialization pathways
This work demonstrates how nanomaterials and additive manufacturing can disrupt conventional molecular testing—making rapid, on-site diagnostics possible anywhere, from clinics and farms to industrial sites and homes.
