Nanotechnology Initiative Division

Nanotechnology is the development and use of techniques to study physical phenomena and develop new devices and material structures in the physical size range of 1-100 nanometres (nm), where 1 nanometre is equal to one billionth of a meter. Nanotechnology impacts all areas of our lives. These include materials and manufacturing, electronics, computers, telecommunication and information technologies, medicine and health, the environment and energy storage, chemical and biological technologies and agriculture.
The impact of nanotechnology on the field of electronics is far reaching. Although advances in silicon technology continue to revolutionize micro/ nanoelectronics, there are cases where non-Si device and component technologies provide superior performance. With modern material growth techniques, it is possible to grow and fabricate multilayered nano-structures and devices comprising of different materials with nanoscale thickness. Further, nanotechnology-enabled sensors are providing new solutions in physical, chemical and biological sensing that enable increased detection sensitivity, microsystems integration capability and portability for wide variety of health safety and environmental assessments.
Ministry of Electronics and Information Technology (MeitY) has taken several major initiatives for the promotion of Nanoelectronics research and innovation in the country. Major Nanoelectronics Centres of international standards have been established at premier institutes in the country. The state-of-the-art nanofabrication facilities at these Centres have become very popular both in India and abroad. Also, the Indian Nanoelectronics Users Programme (INUP) initiated by MeitY is being implemented at Centre of Excellence in Nanoelectronics (CEN) at IISc and IIT Bombay and has provided a great opportunity for R&D community all over the country for accessing state of the art nanofabrication facilities for undertaking research and skill development in Nanoelectronics. About 400 researchers are being imparted hands-on training in Nanofabrication at these centres every year. The research activities have so far resulted in a large number of research publications and significant number of innovations for which patents have been filed.
Some of the technologies developed at the CENs have been licensed to a few start-up Indian companies in India. Apart from this, the CENs have worked closely with national laboratories for developing several technologies for strategic applications utilizing the facilities created under MeitY’s initiative. The centres have also started interactions with industry for developing new technologies and products for large scale manufacturing & commercialization. The focus of Nanotechnology Initiatives Division has been towards development of an eco-system for semiconductor manufacturing in India through cutting edge research Projects

Major Research Output
A few of the technologies developed successfully at Centre for excellence IISC, IITB, IITM, IITD under the Nanotechnology Programme are:
Diabetes, Anaemia and Malnutrition, Kidney and Liver disease Monitoring system
Based on electrochemical biosensors research carried out at the Centre for Nano Science and Engineering (CeNSE), a Start-up company PathShodh Healthcare Pvt Ltd has been incubated at IISc Bangalore. PathShodh has introduced first of its kind handheld device with the capability to measure multiple biomarkers specifically targeting Diabetes and its complications, Kidney disease, Anemia and Liver related ailments. The product has already been deployed in the field and is currently going through ISO 13485 and CE certification.
PathShodh's existing platform technology, "anuPath (TM)", to measure multiple bio-markers is proposed to be redesigned and validated to test COVID-19. Since, there is no strip based test available for COVID-19 at present anywhere in the world, a disposable test strips utilizing a novel receptor chemistry to perform highly accurate and sensitive COVID-19 antibody (IgG and IgM) test is proposed. The test may be done with tiny finger prick blood sample in shorter time at substantially low cost lesser than ELISA kit. For more details visit: https://pathshodh.com/media.php

Portable Polymerase Chain Reaction (PCR) Platform
Under the NNetRA project funded by MeitY, a  Polymerase Chain Reaction (PCR) System to detect blood related diseases has been developed by IISc to detect Malaria and other blood related diseases. The system uses PCR-Thermal Cyclers in conjunction with adapter chain and fluorescence reader unit.  Technology for the same has been transferred to a Start-up Shanmukha Innovations Pvt. Ltd incubated at IISc for its commercialization.
This start-up would be developing portable molecular diagnostic lab for COVID-19 testing. Instead of existing RT-PCR for testing COVID-19, it uses PCR-Thermal Cyclers in conjunction with adapter chain and fluorescence reader unit, considered equivalent to that of gold standard technology namely RT-PCR. The system would enable shorter turn-around-time compared to 24-72 hours with central labs with capability of processing and testing larger number of samples/day/unit.

Gas Sensors
Under the NNetRA project of MeitY, Gas sensors (for multiple identified gases NO2, O2 and N2H4 and H2) have been developed by IISc Bangalore with the following deliverables:

  • Scaling up of metal oxide gas sensor technology for routine production.
  • Long term reliability assessment of metal oxide gas sensors.
  • Field deployment of gas sensors with potential partners from strategic sectors and industry.
  • SCL, Mohali has been given the technology for the development of NO2, O2 and N2H4 and H2 sensors for strategic applications. Field trials of these sensors have already been performed at SHAR, Sriharikota. The sensors are also undergoing field trials for their possible use in railway coaches.
  • Since N2 and O2 gases are mixed in different ratios in ventilator, it is important to measure the precise concentration of O2 in the gas pushed by ventilator into patient’s lungs. In a very short time, using 3D printed package, the project team was able to deliver O2 gas sensor chip to be used in ventilators.
  • This sensor chip is also being used in another project on “Oxygen concentrator”, to generate 100% oxygen from ambient air by filtering N2 gas out in a membrane.
