(a) Comparison between micro- and nanoparticles as force generation components with microscale (i) and nanoscale (ii) tweezers, respectively. (iii) Modes of force stimulation. (b) Applications of magnetic nano-tweezers (MNTs) in the regulation of biological process on various spatial and temporal scales. (i) Regulation of cell signaling on various biological spatial scales from organisms/tissues, to single cells and to single molecules is possible by manipulating the nanoparticles with an external magnetic field. (ii) Extremely fast or slow mechanotransduction processes can be precisely recapitulated using MNTs.
