Photonic technologies have emerged as powerful tools for advancing biochemical sensing and micromanipulation, offering novel approaches in life sciences, diagnostics, and environmental monitoring. In this talk, we will present multidisciplinary work from the Centre of Applied Photonics at INESC TEC, focusing on the development of state-of-the-art photonic platforms. Key innovations in optical fiber sensors, integrated microresonators, and optical tweezers for micromanipulation and sensing will be introduced, with a focus on their specific applications.

Building on these developments, the capabilities of femtosecond (fs) laser microfabrication in creating high-sensitivity monolithic optofluidic platforms will be showcased, with examples such as high-Q resonators coupled with suspended integrated waveguides being introduced. The application of fiber optic technology for high-sensitivity plasmonic sensing of relevant biomolecules will also be explored.

Finally, we will discuss the potential of optical tweezers in extracting valuable information from target bioparticles, demonstrating their utility as a powerful diagnostic tool. These advancements illustrate how photonic technologies continue to push the boundaries of biochemical sensing and micromanipulation, offering exciting possibilities for future research and real-world applications. Ultimately, the integration of these technologies holds the promise of revolutionizing diagnostic capabilities and enhancing our understanding of complex biological systems. By fostering collaboration across disciplines, we can accelerate the development of innovative solutions to pressing global challenges.
