Abstract
A DNA chip includes a large number of minute spots formed by dripping sample solutions onto a base plate. The base plate is provided with positional deviation-correcting means for displacing the spots and automatically correcting any positional deviation of each of the spots. The positional deviation-correcting means includes any one of at least one projection, at least one recess and electric field-generating means for providing charged states on the base plate centered at a correct position for each of the spots supplied on the base plate.
Claims5
A DNA chip comprising a plurality of sample spots comprising DNA supplied on a base plate, wherein:
- said base plate is provided with positional deviation-correcting means for displacing said plurality of sample spots and automatically correcting any positional deviation of each of said plurality of sample spots after said sample spots are supplied on said base plate, said base plate comprising a plurality of said sample spots at correct positions,
- wherein said positional deviation-correcting means comprises at least one pointed projection positioned on said base plate, said at least one projection being centered at a correct position for each of said plurality of sample spots supplied on said base plate.
A method for producing a DNA chip comprising a plurality of sample spots comprising DNA supplied on a base plate, comprising the steps of:
- providing a base plate having positional deviation-correcting means for displacing said plurality of sample spots and automatically correcting any positional deviation of each of said plurality of sample spots after said sample spots are supplied on said base plate;
- supplying said plurality of sample spots onto said base plate;
- and
- correcting any positional deviation of each of said plurality of sample spots,
- wherein said positional deviation-correcting means comprises at least one pointed projection positioned on said base plate, said at least one pointed projection being centered at a correct position for each of said plurality of sample spots supplied on said base plate.
