IISER Bhopal Team Creates Organic Molecules That Emit Near-Infrared Light

Career & Courses

 A team of researchers at the Indian Institute of Science Education and Research (IISER) Bhopal has achieved a significant breakthrough in the field of organic chemistry. The team has successfully developed a new class of organic molecules that emit near-infrared (NIR) light. This discovery holds great potential for various applications, particularly in the field of biomedical imaging techniques, which rely on the use of NIR light to visualize tissues and cells deep within the body.

Development of Organic Molecules Emitting NIR Light :

The IISER Bhopal team employed innovative synthetic chemistry techniques to design and synthesize a unique class of organic molecules capable of emitting NIR light. These molecules were carefully engineered to possess specific electronic and structural properties that enable them to emit light in the near-infrared range when stimulated. This emission wavelength is particularly advantageous for biomedical applications due to its ability to penetrate tissues more deeply compared to visible light. 

Potential Biomedical Applications :

The development of organic molecules emitting NIR light opens up numerous possibilities in the field of biomedicine. One major application lies in the area of biomedical imaging, where these molecules can be used as contrast agents for imaging techniques such as near-infrared fluorescence imaging (NIRF) and optical coherence tomography (OCT). The enhanced tissue penetration of NIR light allows non-invasive imaging of deep-seated organs and tissues with higher resolution. 

Additionally, NIR light-emitting molecules can be employed in the field of photodynamic therapy (PDT). PDT utilizes light-sensitive compounds to selectively destroy cancer cells. By incorporating these newly developed organic molecules into PDT agents, researchers can potentially improve the precision and effectiveness of cancer treatments.

Furthermore, the ability to emit NIR light can also facilitate advances in optogenetics, a technique that uses light to control and manipulate genetically modified cells. The development of organic molecules emitting NIR light expands the toolbox of optogenetics, enabling researchers to target and control cells in deeper regions of the body.

The groundbreaking research conducted by the IISER Bhopal team in creating organic molecules that emit near-infrared light holds tremendous promise in the field of biomedicine. These molecules provide a novel tool for biomedical imaging techniques, allowing deeper visualization of tissues and cells. Moreover, their potential applications in photodynamic therapy and optogenetics could revolutionize cancer treatment and cell manipulation methods.


The development of these organic molecules is a testament to the innovative capabilities and research excellence of IISER Bhopal. It highlights the institution's commitment to advancing scientific knowledge and contributing to cutting-edge research in various fields. As this breakthrough continues to progress, it is expected to pave the way for future advancements in the biomedical sciences, ultimately leading to improved diagnostic and therapeutic approaches that benefit human health and well-being.
