Abstract
A system and method for bonding and unbonding of small objects using small adhesive particles. The system and method includes the use of a plurality of optical tweezers to manipulate objects to be bonded and adhesive particles suspended in a fluid. The objects to be bonded (or unbonded) and the adhesive particles are positioned by lower power optical tweezers and then an intense bonding optical tweezer is activated to cause the adhesive to join the objects together (or used to unbond objects).
Claims17
A method for bonding objects, comprising:
- providing a plurality of light beams for manipulating purposes;
- providing a fluid medium;
- providing at least two objects for bonding to each other and the objects being suspended in the fluid medium;
- providing at least one adhesive particle different than the at least two objects to be processed and the at least one adhesive particle suspended in the fluid medium and all of the adhesive particles being unattached to objects;
- and then
- manipulating each of the at least two objects to be processed by using the light beams to directly trap each of the at least two objects to establish a joint area;
- and then
- bonding the two objects together with the at least one adhesive particle by using a bonding light beam to move the at least one adhesive particle to a location near the joint area for establishing a joint bond.
A method for operating on a object, comprising:
- providing a plurality of light beams;
- providing a fluid medium;
- providing an object to be processed and the object being suspended in the fluid medium;
- providing at least one adhesive particle different than the object to be processed and the at least one adhesive particle being suspended in the fluid medium and all of the adhesive particles being unattached to any objects;
- manipulating the object by interacting with the plurality of light beams and then interacting the at least one adhesive particle with the object by using a bonding light beam to manipulate the at least one adhesive particle;
- and then
- forming a combined structure selected from the group consisting of a bonded structure, a chemically reacted structure and an unbonded structure after a bonded structure is established.
