AI-powered nanosensor to find cancer in saliva and blood
A miniaturized neural network enabled nanoplasmonic spectroscopy platform for label-free cancer detection in biofluids
This project uses a small AI-powered sensor to read molecules in saliva or blood to spot head and neck cancer early.

What this research studies
Researchers are building a tiny, low-cost device that reads infrared molecular fingerprints from a drop of saliva or blood without extra chemicals. The sensor uses plasmonic nanostructures to boost signals and a neural network to recognize patterns tied to head and neck cancer. Over the grant period the team will refine the hardware, train the AI with clinical samples, and compare results to current diagnostic methods. The goal is a portable, label-free liquid biopsy that could be used in clinics or at the point of care.
Who could benefit from this research
Good fit: Ideal candidates are people at risk for or diagnosed with head and neck cancer who can provide saliva or blood samples for testing and monitoring.
Not a fit: Patients with cancers outside the head and neck region or whose tumors do not release detectable metabolites into saliva or blood may not directly benefit from this work.
Why it matters
Potential benefit: If successful, this could enable quick, low-cost, non-invasive screening and monitoring of head and neck cancer using saliva or blood samples.
How similar studies have performed: Related methods like mass spectrometry and infrared spectroscopy have shown promise for detecting cancer biomarkers, but a miniaturized nanoplasmonic device with onboard AI for label-free liquid biopsy is largely novel and less tested in patients.
