A focused laser beam acts as both a “phototrap”, bleaching fluorophore molecules that diffuse into the beam path, and as a confocal probe, detecting the excited, unbleached fluorophore molecules still present in the trap. With this focused laser beam, we observe anomalous asymptotic rate laws similar to those predicted for a diffusion-controlled elementary trapping reaction [Formula Presented] in both one and two dimensions. One-dimensional diffusion-limited trapping kinetics are observed in capillaries with [Formula Presented] [Formula Presented]m diameters, while two-dimensional (2D) diffusion limited trapping kinetics are observed with unstirred samples having a quasi-2D geometry. However, in the presence of stirring, the 2D samples exhibit the classical, constant trapping rate. © 1997 The American Physical Society.
