IIT Guwahati researchers advance the use of modified graphene oxide in biomedical applications

Researchers at the Indian Institute of Technology (IIT) Guwahati have developed cost-effective experiments for modifying graphene oxide (GO) that can be used by other academic institutions to train personnel needed for cutting-edge projects in semiconductors, nanoelectronics, healthcare and quantum technologies.

A team led by Rajiv K Kar, assistant professor, at the Jyoti and Bhupat Mehta School of Health Sciences and Technology in IIT-Guwahati, made these discoveries regarding the use of modified graphene oxide for biomedical applications, according to a recent announcement.


The IIT-Guwahati researchers are focusing on a specific functional modification of graphene involving the attachment of an amino acid, Cysteine or simple amine group.

Speaking on the functionalized Graphene oxide, Kar said: "We studied how amino acid-modified Graphene Oxide behaves in liquid. We found that a particular bond in Cys-GO sheets enhances their stability, reducing random movements. This research has the potential to aid in the development of biomarkers for disease detection". 

The team's extensive knowledge of Graphene-based materials has led to the development of innovative laboratory experiments designed to provide students with hands-on skills and inspire them to explore the possibilities of advanced materials. These experiments are integrated into a Biomedical Science and Engineering (BMSE) course at the Jyoti and Bhupat Mehta School of Health Sciences and Technology, the release added.

Speaking about the innovative course, Kar said: "These low-cost laboratory experiments are applicable also to chemical, material science, nanotechnology and interdisciplinary courses. We believe these techniques will help in developing hands-on skills and inspire budding researchers and future scientists to find innovative solutions in the field of Biomedical Science and Engineering".
