ABSTRACT:
A method of multiphoton photosensitizing comprises(a) providing a multiphoton-activatable, photoreactive composition comprising(1) at least one reactive species that is capable of undergoing an acid- or radical-initiated chemical reaction, and(2) a photoinitiator system comprising photochemically-effective amounts of(i) at least one type of semiconductor nanoparticle that has at least one electronic excited state that is accessible by absorption of two or more photons, and(ii) a composition that is capable of interacting with the excited state of the semiconductor nanoparticle to form at least one reaction-initiating species; and(b) irradiating the multiphoton-activatable, photoreactive composition with light sufficient to cause absorption of at least two photons, thereby inducing at least one acid- or radical-initiated chemical reaction where the composition is exposed to the light.
