A method for holding samples for analysis and an apparatus thereof includes a testing plate with a pair of opposing surfaces and a plurality of holes. Each of the holes extends from one of the opposing surfaces to the other one of the opposing surfaces. The holes are arranged in groups, where each group has at least two rows and two columns of holes. The groups are arranged in sets, where each set has at least two rows and two columns of groups. To analyze samples, at least one of the opposing surfaces of the testing plate is immersed in a solution to be analyzed. A portion of the solution enters openings for each of the holes in the immersed opposing surface. Once the holes are filled with solution, the testing plate is removed and is held above a supporting surface. Surface tension holds the solution in each of the holes. The solution in one or more of the holes is then analyzed and the solution in one of these holes is identified for further study.

A spatially fixed library of mutated cells and a method for creating such a library. The library is created by creating a set of cells having a genetic diversity, causing the cells to multiply and express phenotypes, preparing a solution containing the cells diluted in a medium, populating a plurality of through-holes of a testing plate with the solution such that surface tension holds the solution in respective through-holes, and analyzing the phenotypes of the cells in the solution on a hole-by-hole basis. Cells expressing specified phenotypes may then be retrieved.
