Universal transduction scheme for nanomechanical systems based on dielectric forces
NationallizenzNature Publishing Group | 2009|example, trapping microscopic particles in an optical tweezer, where the trapping force is controlled via the intensity of a laser beam, or ... -
The bacteriophage φ29 portal motor can package DNA against a large internal force
NationallizenzNature Publishing Group | 2001|use optical tweezers to pull on single DNA molecules as they are packaged, thus demonstrating that the portal complex is a force-generating ... -
The dynamics of partially extended single molecules of DNA
NationallizenzNature Publishing Group | 1997|single molecules of DNA held in a partially extended state with optical tweezers. We find that the motion of the DNA can be described by linearly ... -
Elasticity and unfolding of single molecules of the giant muscle protein titin
NationallizenzNature Publishing Group | 1997|done mechanical experiments on single molecules of titin to determine their visco-elastic properties, using an optical-tweezers technique. On a ... -
Polymer physics of the cell

Peptide bond formation destabilizes Shine–Dalgarno interaction on the ribosome
NationallizenzNature Publishing Group | 2007|repetitive cycles of transfer RNA selection, peptide bond formation and translocation. Here we demonstrate an optical tweezer assay to measure the ... -
Isolation of a hyperthermophilic archaeum predicted by in situ RNA analysis
NationallizenzNature Publishing Group | 1995|staining59 and cloning by 'optical tweezers'10,11. Our result validates polymerase chain reaction data on the existence of large archaeal ... -
A diffusion barrier maintains distribution of membrane proteins in polarized neurons
NationallizenzNature Publishing Group | 1999|proteins using optical tweezers, we show here that some membrane proteins exhibit markedly reduced mobility in the initial segment of the axon ... -
Fast axonal transport is required for growth cone advance
NationallizenzNature Publishing Group | 1993|reversible, inhibition of fast axonal transport with laser optical tweezers inhibits growth cone motility if cytoskeletal attachment to the cell body ... -
The motor protein myosin-I produces its working stroke in two steps
NationallizenzNature Publishing Group | 1999|‘rocks’ into one or more subsequent, stable conformations,. Here we use an optical-tweezers transducer to measure the mechanical transitions made ... -
Diffusion of point defects in two-dimensional colloidal crystals
NationallizenzNature Publishing Group | 2001|two-dimensional colloidal crystals by manipulating individual particles with optical tweezers. Direct imaging of these defects verified that ... -
Automated electrorotation: dielectric characterization of living cells by real-time motion estimation
