Method and system of optical manipulation of micrometer-sized objects, which comprises the steps of placing a pattern () of a certain material on a surface (), wherein said material is capable of sustaining surface plasmons; placing a solution () comprising micrometer-sized objects in contact with said surface () and said pattern (); applying at least one optical beam () at a certain wavelength and with a certain incident angle (&#x3a6;) to said surface () for certain time interval, thereby creating surface plasmons forces at said surface (), in such a way that said micrometer-sized objects are trapped by the pattern () in a stable and selective way. Optical trap and use thereof as a tool for optically driven lab-on-a-chip.
