Quantum Nanoparticles to Detect and Image Tumors

Electro-Optics post doctoral student, Ahmad Salman Ogli, has been conducting research on imaging and image processing of cancer tumors using quantum nanoparticles.

In a meeting with the Iran Nanotechnology Initiative Council, he said that cancer is diagnosed through clinical tests. But these traditional methods take a long time, and most often are both insensitive and inaccurate. These problems have urged researchers to focus on using nanoparticles to track tumors and process images.

He says his research was a collaboration between engineering and medical students. The wavelength that helped capture images was initially examined. This led to the discovery that infrared spectrum was better than visible light because of its low dissipation and diffraction. This method was therefore followed to help the team create the nanoparticles design to move  the operational wavelength drop into the infrared range. Care also had to be taken to see that the wavelength was not unduly magnified. Infrared wavelength was chosen to capture the image because it enhances the photoluminescence property of the nanoparticles.

The report on this research has appeared in the Journal of Nanoparticle Research.
