Here we report the use of optoelectronic tweezers and dynamic virtual electrodes to address multiwalled carbon nanotubes (MWCNTs) with trap stiffness values of approximately 50 fNmum. Both high-speed translation (>200 mums) of individual-MW...
Observation of polarization-gate based reconstruction quality improvement during the process of turbidity suppression by optical phase conjugation [0.03%]

We present experiments that study the impact of polarization selection on the phenomenon of turbidity suppression by optical phase conjugation. Counter to intuition, we discovered that the preferential utilization of multiply scattered ligh...
Structure of YSi(2) nanowires from scanning tunneling spectroscopy and first principles [0.03%]

We report on a selective and nondestructive measurement of mRNA (messenger ribonucleic acid) expression levels within a living cell. We first modify an atomic force microscope tip to create a tapered nanoscale coaxial cable. Application of ...
Optically actuated thermocapillary movement of gas bubbles on an absorbing substrate [0.03%]
