Abstract:
Iranian researchers at Razi Univeristy of Kermanshah made a low-cost nanosensor for detection of the trace of toxic lead ion in water and aqueous solutions by means of gold nanoparticles.

Lead Ions Detected in Water by New Low-Cost Nanosensors

Iran | Posted on December 27th, 2010

This nanosensor, having rapid operation, is produced by supersensitive azacrown ether-functionalized gold nanoparticles with no need to expensive materials and methods.

Noting that the aforementioned nanosensor shows the result without using DNA, dye molecules, enzymes, or any other additive, Dr. Abdolhamid Alizadeh, faculty member at Nanoscience and Nanotechnology Research Center (NNRC), faculty of chemistry, Razi University of Kermanshah told INIC that this nanosensor operates just ocularly.

"The detection precision of this nanosensor is of nanomolar, it operates fast and more importantly, it benefits from low cost fabrication technology," he added.

"First, thiol-bearing arms are added to a receiver able of forming complex with metals. Then, they are bonded with gold nanoparticles surface, which are presynthesized, via thiol-gold bond. Lastly, the performance of sensor is analyzed and validated by studying changes in optical properties of nanoparticles before and after addition of aqueous solution containing various metallic ions," he said, explaining about the procedure of the research.

Alizadeh also referred to a Singaporean company's interest in commercializing the aforesaid nanosensor, and noted, "The initial consultations with the company are underway."
