Abstract:
The present invention is designed for use with a biolistic bombardment device having a cold gas shock wave splitter that divides a cold gas shock wave into two or more separate pressure waves that burst into one or more macrocarrier disks so as to create two or more separate microparticle groups. In various embodiments, the present invention provides a divider that is configured to define two or more separate bombardment areas, each configured to contain a respective target and to receive a separate one of the microparticle groups created by a cold gas shock wave splitter. In such a manner, the present invention avoids mixing of microparticles between microparticle groups and allows for independent biolistic bombardment of the targets.
