  Zeptonewton force sensing with nanospheres in an optical lattice 

  Ranjit, Gambhir; Cunningham, Mark S.; Casey, Kirsten; Geraci, Andrew A. (2016)

  Optically trapped nanospheres in high vacuum experience little friction and hence are promising for ultrasensitive force detection. Here we demonstrate measurement times exceeding 10(5) s and zeptonewton force sensitivity ...
