The European Union has launched an innovative research initiative called **Dinamo**, aiming to develop a non-invasive nanotechnology-based platform for real-time monitoring of biomolecules within cancer cells. At the heart of this project is the **nanodiamond**—a material long anticipated for its unique properties in medical applications.
Nanodiamonds, specifically **fluorescent nanodiamond particles (NDPs)**, are being explored as powerful tools for biomedical sensing. A research team led by the EU has been investigating these tiny particles, which exhibit exceptional suitability for use as medical probes. Their small size and high accuracy make them ideal for studying intracellular mechanisms at the molecular level.
Traditionally, detecting biomolecules inside cells was limited to short observation periods. The Dinamo project focuses on replacing conventional fluorescent dyes used in cancer cell studies with more advanced nanodiamond-based probes. This shift offers greater precision and longer-term monitoring capabilities.
One of the most significant advantages of NDPs is their **high biocompatibility**, long-lasting presence within cells, and minimal impact on cellular functions. These nanodiamonds can be engineered with specific surface properties, allowing them to interact with biological molecules such as DNA or proteins. Once inside the cell, their luminescence and magnetic characteristics change depending on their environment, making them excellent indicators of cellular activity.
Scientists have successfully used NDPs to detect early-stage cancer changes and even perform preliminary treatments. This technology is now being tested in several institutions, including the **Gustav Roussy Cancer Institute in France** and **Paris Teachers College (ENS)**. Future developments will be carried out under the **DIAMANT project**, a follow-up to Dinamo.
Experts like **Fedor Jelezko** from Ulm University in Germany believe that the use of nanodiamonds in drug delivery systems could revolutionize treatments for various diseases, especially cancer. The ability to track drug-carrying nanodiamonds using fluorescence microscopy makes them highly valuable for precise intracellular drug delivery.
However, some scientists remain cautious. **François Treussart**, a physics professor at ENS, points out that while nanodiamonds show great promise, they are chemically inert and may not be easily metabolized by the human body. Although successful in lab settings, their application in human trials remains uncertain due to potential unknown risks.
Despite these concerns, many researchers still see strong potential for nanodiamonds in diagnostic tools and regenerative medicine. Recent studies by the **Fluorescence-ND project team** at the Central Research Institute of Taiwan further support this view.
Currently, the theoretical phase of the Dinamo project has concluded, and the **University of Stuttgart** is working on developing actual NDP-based probes. So far, the technology has shown high accuracy in diagnosing breast and colorectal cancers, though it is less effective for other types of cancer.
As the project moves forward, numerous questions will guide future research efforts. The Dinamo initiative continues to push the boundaries of nanotechnology in medicine, offering a glimpse into a future where early cancer detection and targeted treatment may become routine.
