1. A method of using a spatial surface configuration for selective particle interaction, said method comprising:

  • providing a heterogeneous surface comprising a surface member and a plurality of components thereon, said components spaced about said surface member and having a density thereon, said surface heterogeneity providing different interactions of said surface member and said spaced components with a particle exposed thereto;

    exposing a particle to said heterogeneous surface; and

    sensing at least one of physical and chemical interaction of said particle with said heterogeneous surface, said interaction selective for said particle.
