A team of researchers from the U.S. and India has developed a powerful new sensor that can identify dangerous levels of iron in water faster, cheaper, and with far greater accuracy than existing methods. The project was led by Fei Yan, professor at North Carolina Central University (NCCU). Yan is also part of the NSF PREM for Hybrid Nanoscale Systems.
The collaboration—funded by NSF and the U.S. Army Research Office—brought together experts in chemistry, materials science, and computer modeling from NCCU, Pennsylvania State University, and IIIT Bhopal. Postdoctoral fellows Amit Kumar Shringi and Rajeev Kumar, along with Rajneesh Chaurasiya and PhD student Justin Lin, played key roles. They recently published their research in the journal Nanoscale.
