Provided is a target transport system which is advantageous in simplifying and downsizing a configuration in production of radio-isotopes using an accelerator and in which components are hardly affected to be damaged by radiation. The target transport system includes: a transport pipeline through which a target body is transported; a target holding part that holds the target body and allows the target body to be irradiated with particle beams; and a pump, the transport pipeline, and a target entry port that transport the target body to the target holding part by a cooling water. The pump, the transport pipeline, and the target entry port cause the cooling water to flow in the transport direction, and the target body is recovered from the transport pipeline by the cooling water.

The invention, provides a method, apparatus and system for separating blood and other types of cellular components, and can be combined with holographic optical trapping manipulation or other forms of optical tweezing. One of the exemplary methods includes providing a first flow having a plurality of blood components; providing a second flow; contacting the first flow with the second flow to provide a first separation region; and differentially sedimenting a first blood cellular component of the plurality of blood components into the second flow while concurrently maintaining a second blood cellular component of the plurality of blood components in the first flow. The second flow having the first blood cellular component is then differentially removed from the first flow having the second blood cellular component. Holographic optical traps may also be utilized in conjunction with the various flows to move selected components from one flow to another, as part of or in addition to a separation stage.
