Abstract :
Optoelectronic tweezers (OET) is a new optical manipulation technique to trap individual particles with sizes ranging from tens of nanometers to hundreds of micrometers [1]. Using optically-controlled dielectrophoretic force, OET enables complex, dynamic manipulation functions using light intensities up to 100,000 times lower than that of conventional laser tweezers. This paper will review the principle of the OET, and highlight recent advances in manipulating semiconductor nanowires and biological cells in culture media.
