Methods and apparatus for enabling a clean, fragile object to be transported while protecting both front and back surfaces of the object are disclosed. According to one aspect of the present invention, a thermophoretic wand that is arranged to carry an object having a first temperature includes a first element, a contact surface, and an air supply. The first element has a first opening defined therein, and is maintained at a second temperature that is lower than the first temperature such that when the first element is in proximity to the object, a thermophoretic forces may be such that particles present between the object and the first element are driven away from the object. The air supply applies a vacuum of a first level through the first opening to suction the object against the contact surface.
