Process and apparatus for fragmenting biomaterials
First Claim
1. In a process for fragmenting a biomaterial and isolating and recovering a component thereof, the improvement comprising performing said fragmenting by nebulizing a liquid containing said biomaterial, said nebulizing including directing the liquid containing the biomaterial against a nebulization barrier so as to cause the biomaterial to be fragmented.

Abstract
Described is an improved process for fragmenting a biomaterial and isolating and recovering a component thereof. The preferred improved process includes the step of performing the fragmentation by nebulizing a liquid medium containing the biomaterial. A preferred process for fragmenting isolated DNA includes the step of nebulizing a fluid containing the DNA. This preferred process provides randomness superior to prior known DNA fragmentation methods, as well as other important advantages. An improved nebulization device is also described.

22. A process for determining a sequence of a DNA strand, comprising the steps of (i) nebulizing a liquid containing multiple copies of the DNA strand to thereby form DNA fragments, said nebulizing including directing the liquid containing the copies of the DNA strand against a nebulization barrier so as to cause the copies of the DNA strand to be fragmented, and (ii) determining by analysis of said fragments, a sequence of said DNA strand.
