A team of nanoelectronics researchers from Sharif University of Technology has introduced two advanced diagnostic systems for measuring blood hemoglobin, one of which operates completely non-invasively, requiring no blood sampling. The unveiling took place at the 16th International Nanotechnology Exhibition of Iran (Iran Nano 2025).

The two systems utilize optical and photonic technologies designed to achieve greater precision in biomedical parameter measurement.
Mahboobeh Esmaeilpour, a PhD candidate in nanoelectronics at Sharif University of Technology, explained that one system performs the measurement using only a single drop of blood, while the second device functions entirely non-invasively, estimating hemoglobin levels through the skin.
She noted that the non-invasive system operates on a mechanism similar to a pulse oximeter, commonly used for blood oxygen monitoring. The device integrates nanomaterials that significantly enhance the sensitivity and accuracy of the optical sensor. “Our goal in participating in the Iran Nano Exhibition,” Esmaeilpour added, “is to gather technical feedback from the nanotechnology community on the effectiveness of these nanomaterials in improving non-invasive diagnostic systems.”
Rapid, accurate, and non-invasive measurement of hemoglobin
No blood sampling or consumable materials required
Lightweight and portable, suitable for field use
Reduced diagnostic time and cost
Strong export potential to regional healthcare markets
These systems represent a significant step toward integrating nanomaterials with optical sensing technologies, paving the way for faster, more accessible, and affordable medical diagnostics in the field of digital and portable healthcare.
