Researchers from the H2020 FET-OPEN project STRETCHBio project, led by Prof. Albert Romano-Rodríguez (Micro and Nanotechnology and nanoscopies for Electronic and Electrophotonic Devices (MIND)), have made a significant leap in force sensing and biosensing technologies with their latest study published in ACS Nano, titled “Strong Cavity-Optomechanical Transduction of Nanopillar Motion.”
The study presents an innovative approach to transducing the motion of nanopillar resonators, which are key for ultra-sensitive force measurements. By engineering silicon nanopillars to achieve light confinement and creating an energy band gap in the near-infrared spectrum, the team developed high-quality optomechanical cavities. This advancement is a major contribution to the broader field of biosensing and force sensing, offering new possibilities for scalable, cost-effective solutions.
