Definitions
- This invention relates to the sorting of biological cells into spatially separate sub groups.
- the criteria for sorting may be applied to measurements obtained by any technique or techniques suitable for microfabricated or electronic implementation on a substrate.
- Microfabrication and microelectronic techniques offer a number of actual and potential measurement techniques that may be applied to characterize biological cells.
- PCT/GB91/00289 and morphological measurements.
- morphological measurements When suitably implemented such techniques can be applied on a cell by cell basis.
- microelectromechani ⁇ al structures and their formation by selective CVD techniques, are disclosed in: "Selective Chemical Vapor Deposition of Tungsten for Mi ⁇ roelectromechani ⁇ al Structures" by N. C. MACDONALD et al. , Sensors and Actuators, 20 (1989) 123-133.
- the so-called “microtweezers” are activated by control voltages applied to electrodes.
- such a machine is implemented by utilising a microfabricated moveable structure, preferably microfabricated beams, to direct cells between distinct spatial locations.
- FIG. 1 is a topologi ⁇ al plan view of a substrate on which a cell sorter is formed.
- the cells to be sorted whose diameters may be only a few micrometres, are fed sequentially from an entry port 1, via a guiding structure 2, past a generalised sensing device or zone 3.
- the deflectable beams 4, 5, 6, are set into appropriate states to direct the cell into a particular destination, for example, a hole 7, 8, 9 or 10 etched through the substrate.
- the destination is structure 9.
- the beams, along with associated bifurcations can be extended to a tree structure of ' n' levels thereby yielding 2 possible sorting sub ranges.
- the absolute lengths of the channels are as short as possible while maintaining compatibility with interconnecting structures.
- the shafts 1, 3, 7-10 may be fabricated by selective etching as disclosed in the copending International Patent Application referred to above; the etched substrate is closed by a glass/silica cover, thereby forming the channels as tunnels.
- Typical dimensions of the entry port 1 are 500 ⁇ m or less square; of the sensing zone about 100 ⁇ m square; of the channels about 5 to 10 ⁇ m in width and depth; of the holes (shafts) 7 - 10 about 500 ⁇ m or less square; and of the beams, which are typically of constant rectangular section, about 150 ⁇ m long by 3 ⁇ m square.
- the overall dimensions of the device could be l ⁇ m square.
- the beams are activated by selective control voltages applied as signals for control circuitry (not shown) operated, for example, under the control of a microprocessor or other computer.
- the computer is programmed to control the beams' deflection in response to the desired cell-sorting procedural steps.
