IIT Madras Develops CNT-Enhanced Concrete for Sustainable Infrastructure

October 2024

Researchers at IIT Madras have successfully incorporated functionalized Carbon Nanotubes (CNTs) into concrete mixtures, demonstrating a significant increase in compressive strength and durability while reducing the overall carbon footprint of construction. This breakthrough leverages the exceptional mechanical properties of CNTs to create 'smart concrete' that is also capable of self-sensing cracks, offering a sustainable solution for long-lasting infrastructure projects. This aligns with India's push for green building materials and smart city development. [Source: IIT Madras Press Release, 2024]

CSIR-NCL Pioneers CNT-Based Sensors for Early Disease Detection

March 2025

Scientists at CSIR-National Chemical Laboratory (NCL) in Pune have developed highly sensitive and selective biosensors utilizing functionalized Carbon Nanotubes (CNTs) for the early detection of specific disease biomarkers, including certain types of cancer and viral infections. These sensors offer rapid, point-of-care diagnostics, potentially revolutionizing healthcare accessibility in remote areas. The high surface area and excellent electrical conductivity of CNTs enable ultra-low detection limits, promising a significant leap in preventive medicine. [Source: CSIR-NCL Annual Report, 2025]
