Abstract: In one embodiment, a method for correcting feature overlap in biological probe array data is described that comprises (a) receiving a first set of data comprising an intensity value for each of a plurality of features associated with a probe array; (b) calculating a crosstalk parameter for the first set of data using the intensity values of one or more test features and a plurality of features that neighbor each test feature; and (c) applying the crosstalk parameter to each intensity value in the first set of data to produce a second set of data.

Abstract: A method and apparatus are disclosed which precisely characterizes the physical properties of particles (20) (21). The apparatus balances the force of gravity (22) (23) against an induced upward force (24) (25) and measures the elevation (27) (28) of suspended particles. The upward force is generated by a structure (26) containing elements and signals that repel the particles.
