Abstract
A method for forming a polymer particle is provided which involved irradiating a polymer solution with a laser beam. The polymer particle is formed at the focal area of the beam. The particle is reversible and disappears upon discontinuing the irradiation. Irreversible particles can be formed by including a reactive monomer in the solution. The particles are trapped by the beam and may be moved for processing and modification by moving the laser beam.
