” Recent developments in the field are moving toward obtaining direct force measurements by detecting light momentum changes. “
D. Craig et al., ACS Photonics, 2015
“ This makes the direct force measurement method a prime choice, e.g., for in vivo measurements in biological samples. ”
G. Thalhammer et al., Opt. Express, 2015
“ With the ultimate goal of making well-calibrated force measurements in vivo, we compared three different calibration methods. Ultimately, we favor the momentum-change approach, which is easier to implement. ”
Y. Jun et al., Biophys. J., 2014
“ The light momentum method has significant advantages, as the calibration performed in water remains valid regardless of the media in which the measurement is performed. ”
