Claim:
1. A method for sampling and separating submicron-sized particles in an environmental sample, said method comprising the steps of: collecting a sample suspected of containing submicron-sized particles from the environment, wherein said submicron-sized particles are in the size range of from about 5 to 1,000 nanometers; separating the submicron-sized particles based on size into at least one size range; counting the size separated submicron-sized particles using a microscale particle counter, said particle counter comprising at least one cantilever each corresponding to submicron-sized particles of a particular size range, said cantilever being deflectable from a first to a second position to permit passage of the submicron-sized particle therethrough, wherein the corresponding deflection of the cantilever generates a count signal; and collecting and storing the submicron-sized particles passed by the cantilever in a particle holder.
