NITK Researchers Develop Advanced Antimicrobial Coating for Orthopaedic Implants
NITK Develops Antimicrobial Coating for Implants

Researchers at the National Institute of Technology Karnataka (NITK) Surathkal have developed an advanced bioactive, mechanically durable, and localised antimicrobial coating technology for orthopaedic implants, with particular application in hip and knee joint replacements. The patented innovation marks a significant milestone in indigenous biomedical engineering and represents a major step forward in improving patient outcomes for millions of orthopaedic implant recipients across India and globally.

Addressing Implant Challenges

The team developed a durable bioactive and antimicrobial composite coating that can be directly applied onto implant surfaces using an optimised high-velocity oxy-fuel (HVOF) thermal spray process. This coating is engineered to deliver localised antimicrobial protection while simultaneously improving mechanical durability, wear resistance, coating adhesion, and bone integration. The enhanced osseointegration enables stronger bonding between bone and implant, while the antimicrobial functionality combats bacterial growth at the implant site, substantially reducing the risk of post-surgical infections.

Promising Preclinical Results

Preclinical studies demonstrated promising performance compared to conventional implants currently available in the market. The technology has the potential to significantly reduce the need for revision surgeries and improve long-term patient outcomes.

From Research to Startup

The innovation has resulted in multiple international research publications and has been granted a patent. The technology was developed by Dr Sudhakar C Jambagi, associate professor in the Department of Mechanical Engineering, and his doctoral student Deep Shankar, who completed his PhD under Jambagi's supervision. Deep Shankar has since founded and leads the deep-tech startup established to commercialise this breakthrough technology. The team is currently working toward clinical translation and commercialisation.

Aligned with National Initiatives

The innovation has been developed under the 'Make in India' initiative and is fully aligned with the Government of India's vision of 'Swastha Bharat' and 'Viksit Bharat'. This indigenous solution promises to enhance the quality of life for orthopaedic implant recipients while supporting national healthcare goals.
