Abstract
We observed an enhancement of two-photon excited fluorescence of biological label molecules in aqueous solution, brought about by the addition of a small concentration of silica micro-spheres. The effect is attributed to the so-called photonic jets, a region of high light intensity formed in the vicinity of the spheres as a consequence of near-field focusing.
