Researchers at the University of Otago have developed an innovative method combining atomic force microscopy (AFM) with artificial intelligence (AI) to detect oral cancer earlier and more accurately by identifying nanoscale changes on cancer cell surfaces. The study, led by Simon Guan, Peter Mei, Dawn Coates, and Richard Cannon, published in the journal ACS Nano, highlights how this approach enhances diagnostic accuracy compared to traditional methods, potentially improving patient outcomes and advancing precision medicine.
With approximately 390,000 new oral cancer cases globally in 2022, the researchers emphasize the need for reliable early detection tools and hope to expand the clinical application of AFM technology. The findings also suggest potential pathways for novel cancer therapies based on the nanophysical properties of cancer cells.
Researchers from the University of Otago have developed an innovative method for oral cancer detection by integrating atomic force microscopy (AFM) with artificial intelligence (AI).

Early detection’s potential to improve treatment outcomes underscores its significance. Published in the prestigious journal ACS Nano, this study highlights the method’s credibility and impact on advancing cancer diagnostics.
Globally, oral cancer affects hundreds of thousands annually, with significant mortality rates. The new AFM-AI approach addresses this critical need, offering a more reliable diagnostic tool that could reduce these statistics significantly.
Looking ahead, researchers aim to adapt AFM technology for routine clinical use, potentially expanding its application beyond oral cancer. This could pave the way for novel therapies targeting the nanophysical properties of cancer cells, revolutionizing treatment approaches.
The project was supported by various grants and collaborations across dentistry, nanoscience, and AI, demonstrating the power of interdisciplinary research in addressing significant health challenges.
The researchers utilized atomic force microscopy (AFM) to examine nanoscale mechanical and thermodynamic properties of cancer cells, providing unprecedented insights into their physical characteristics. By integrating AFM data with artificial intelligence algorithms, they developed a system capable of identifying subtle changes in cell behavior that are indicative of malignancy. This approach allows for the detection of oral cancer at an earlier stage than conventional methods, which often rely on visual inspection or biopsy.
The combination of AFM and AI enables precise characterization of cancer cells by analyzing their nanomechanical properties, such as stiffness and adhesion forces. These measurements reveal differences between healthy and malignant cells that are not easily discernible through traditional diagnostic techniques. The use of AI further enhances the system’s ability to interpret complex data patterns, improving diagnostic accuracy and reliability.
This method has the potential to significantly reduce delays in diagnosis, which are often associated with poor treatment outcomes. By enabling earlier intervention, it could contribute to better patient survival rates and improved quality of life. Furthermore, the technology’s adaptability may extend its application beyond oral cancer, offering new possibilities for diagnosing other types of malignancies.
