- Seemesh Bhaskar and Brian Cunningham's team used photonics and nanotechnology to detect microRNA signals linked to cancer up to 8 years before traditional diagnosis, enabling earlier intervention.
- The Nanosensors Group engineered photonic crystal substrates and nano-assemblies that interact with biological systems, allowing detection of molecular changes long before disease symptoms emerge.
- Bhaskar emphasized that magnetic flux in electromagnetic radiation was historically ignored in biosensing, but their lab's simulations successfully accessed it using custom nano-assemblies.
- The research, published in Chemical Reviews, reviewed over a century of scientific work to understand delays in cancer diagnosis and identified photonics as a tool to detect cellular changes at the RNA and DNA level.
- Cunningham's lab fosters a mentorship-driven environment where researchers are treated as faculty and encouraged to focus on societal impact, contributing to the team's breakthrough.
Why it matters: Early cancer detection shifts treatment from reactive to preventive, giving patients and doctors more time for effective interventions. This method targets molecular signals years before tumors form, potentially reducing late-stage diagnoses and improving survival rates through a technology grounded in accessible physics and scalable nanomaterials.
