Recently, a research paper by Professor Wang Yiping's team from the College of Physics and Optoelectronic Engineering at Shenzhen University was featured as the cover article in theNano Lettersjournal. The paper introduces a novel fiber optic-based ultrasensitive nano-vibration sensor. This sensor creates micro-cantilevers at the tip of optical fibers using 3D printing achieved through femtosecond laser-triggered two-photon polymerization. It's applied for quick sensitivity tests of antibiotics and antibacterial drugs. This innovation not only greatly speeds up testing but also streamlines and miniaturizes the experimental apparatus.
