Iranian Researchers Utilize Simple Method to Detect Cancer anywhere in Body
"Producing quantum dot (QD) superluminescent light emitting diode (SLED) for optical and biological applications" is the title of a project completed by Mehdi Molaei, a professor of Valiasr University in Rafsanjan, in the Southeastern province of Kerman.
Molaei said that the technique has applications such as detecting the location of cancerous tumors in addition to their uses in lasers, sensors and cells.
“In the field of nanomaterials, nanosemiconductors, especially nanosemiconductors of group II-VI, have attracted more attention due to their broad applications,” he said according to public relations department of Iran National Science Foundation (INSF)
He added nanosemiconductors have broad applications in different optical, electronic and biological fields.
Semiconductor quantum dots (QDs) are exciting choice for bioimaging applications, notably in cancer imaging, the Iranian researcher said.
“Among nanosemiconductors, quantum dots are of particular importance due to their property of emitting light in the visible range and the tunability of their emission. These nanosemiconductors with size control are broadly used in new-generation light-emitting diodes, which are used in QLED displays as the latest generation of displays, as well as for biological applications, especially for detecting the location of cancerous tumors,” the professor said.
“Presenting new low-temperature methods for the synthesis of nanoparticles with high light emission has attracted lots of interests and is of great importance. For this reason, our goal in this research is to provide a low-temperature, fast, and low-price method to produce quantum dots with high light emission so that they can be used in various optical, electrical, and photocatalytic applications,” the researcher added.
“In this research, the methods used to produce superluminescent light emitting diode (SLED) are among the simple, low temperature, very fast and cheap methods. The costs of producing quantum dots are much lower compared to normal methods, and the yield of production quantum dots will also be very good,” Molaei concluded.
