N2 - We demonstrate the first ever integrated optoelectronic trap in which a particle may be held, guided and interrogated by optical forces alone, using lasers that are microfabricated adjacent to a microfluidic channel, all on a single disposable chip of size less than 1cm2. We demonstrate trapping, shunting and rotation of colloidal and biological matter in this system, and perform spectroscopy of a trapped object. This paves the way for complex multiplexed optical trapping microchips where samples may be analysed and then guided to new interrogation regions with all-optical motion instigated by on-chip lasers, without the need for further external optical apparatus.
