Fibrous structures with fine particles

A fibrous structure comprising surrogate particles bearing functionally active, fine particles, wherein said surrogate particles are entrapped in and bonded to a fibrous matrix in a three dimensional arrangement, wherein the average size of said functionally active, fine particles is on the order of approximately 0.01 to 0.0001 of the average size of said surrogate particles, wherein said functionally active, fine particles are disposed on said surrogate particles in a significantly greater amount than on said fibrous matrix, and are immobilized on said surrogate particles.
