Abstract:
Iranian researchers found a new method to improve the photoluminescence properties of quantum nanoparticles used for tumor imaging which, as a result, contributes to better and more precise diagnosis of cancer.

Scientists Increase Photoluminescence Intensity of Quantum Nanoparticles

Tehran, Iran | Posted on March 23rd, 2011

Ahmad Salman Ogli, postgraduate in Electro-Optics, has been extensively researching on cancer tumor imaging and image processing with the help of quantum nanoparticles (CdSe/ZnS/CdSe/ZnS).

"Cancer diagnoses are being made via medical tests. As these practices are doomed to some weaknesses (for instance, low precision and sensitivity, their time-consuming nature, etc.), researchers are getting increasingly interested in application of nanoparticles in cancer tumor imaging and processing," Salman Ogli told the Iran Nanotechnology Initiative Council.

Emphasizing that "the work was the outcome of a close cooperation between engineering and medicine", he added, "In an initial step, the wavelengths used for filming was studied and it was revealed that infrared spectrum was superior to visible light due to its lower dissipation and diffraction."

"As a result, it was followed to design the nanoparticles structure so that the working wavelength falls in the infrared scope. In addition, extreme enlargement of the nanoparticle dimensions had to be avoided."

Salman Ogli pointed to the choice of infrared wavelength for imaging, which intensifies photoluminescence power of the nanoparticles substantially, as a significant result of the research.

Technical details of this research work have been published in the Journal of Nanoparticle Research.
