We present a method for manipulating preselected quantum dots (QDs) with nanometer precision by flow control The accuracy of this approach scales more favorably with particle size than optical trapping, enabling more precise positioning of nanoscopic particles We demonstrate the ability to position a single QD in a 100 mu m working region to 45 nm accuracy for holding times exceeding : one hour and the ability to take active quantum measurements on the dynamically manipulated QD
