Abstract
A method for depositing particles coated with biological substances onto the concave inner surface of a length of tubing includes the steps of preparing a uniform suspension of coated particles, introducing the particles into the tubing, placing the tubing into a generally horizontal position, removing the evaporable liquid after the particles have settled, and drying the particles. When dry, the tubing is cut into sample cartridges of appropriate length for use in a particle acceleration instrument. An apparatus for performing the method is also disclosed.
