A new study shows that a nanosensor can tell the difference between Autism Spectrum Disorder (ASD) and Intellectual Disability (ID) by measuring nitric oxide (NO) in patient stem cells — even when both conditions share the exact same genetic mutation. This could lead to objective, early diagnosis.
The Research
Researchers at Ohio University's Department of Chemistry and Biochemistry, led by Howard D. Dewald and Abdullah Asif Khan, used a carbon-fiber nanosensor to measure real-time NO production in induced pluripotent stem cells (iPSCs) from patients with ASD, ID, and healthy controls. The study, published in NeuroMarkers on June 29, 2026, found clear differences: ASD cells produced about 6 nanomoles (nM) of NO, ID cells produced 11 nM, and healthy controls produced 65 nM. Remarkably, the sensor could distinguish ASD from ID even when the patient cell lines carried identical genetic mutations. The team used undifferentiated iPSCs, bypassing the need to mature them into neurons, which simplifies the lab process. By using stem cells, the method avoids confounds like age, diet, or medications that affect blood-based biomarkers.
Why It Matters
Currently, ASD and ID are often diagnosed through behavioral observation, which can take years. This nanosensor approach could enable differential diagnosis within the first months of life using a somatic cell sample. For parents and clinicians, an objective biomarker could mean earlier intervention and tailored support. For cognitive science, it shows that real-time molecular analysis can unravel complex neurodevelopmental conditions.
