Researchers from the STRETCHBIO project 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 vertical light confinement and creating an energy band gap in the near-infrared spectrum, the team developed high-quality optical cavities. This advancement is a major contribution to the broader field of biosensing and force sensing, offering new possibilities for scalable, cost-effective solutions.
Moreover, it marks a crucial step towards achieving the STRETCHBIO project’s goal of measuring mechanical tension forces in cancerous tissues in response to specific drug applications, bringing researchers closer to noninvasive, label-free detection of mechanical changes in biological systems.
