1. Researchers from Beihang University and RMIT University have developed a super-resolved photonic force microscopy (SRPFM) method capable of measuring forces as small as 108.2 attonewtons in water. 2. The method utilizes lanthanide-doped nanoparticles and optical tweezers to explore minute forces within biological systems. 3. This innovation improves the resolution and sensitivity of force measurements, potentially benefiting studies in biomechanics and early disease detection.
