Abstract:
A multi-photon excitation system for activating a photoactivable precursor composition, the system comprising:a photon source generating a beam of photons, each photon having a wavelength approximately equal to an integer multiple of the wavelength necessary for single photon excitation in a photoactivatable precursor composition comprising at least two entities selected from the group consisting of proteins, peptides, nucleic acids, bioactive molecules and synthetic polymers; wherein the at least two entities may be the same or different; an optical system for directing the beam of photons to a focal point in at least one first location in the precursor composition; a mechanism for causing relative motion in a prescribed coordinate system between the precursor composition and the photon beam; and a controller for controlling the relative motion between the precursor composition and the photon beam.
