automated in vitro zytotoxizitu00e4tstest

摘要

arrangement for testing of new materials and surface coatings on the effect of biological living cells (zytotoxizitu00e4tstest)in a mikrotiterplatte by a cell culture is provided, the zellenkultur up to 80% coverage grows (start of tests)then with a nutrient medium - agarose mixture u00fcberschichtet,subsequently, the test material by agardiffusion indirectly brought into contact with the cells (agardiffusionstest), characterizedin an indication that a mikroskopanordnung with xyz positioners, the samples in the form of tapes automatically and ausgeschoben,in the microscope the digital image is created, the data packets through an interface for external, by an algorithm with a software package is used.with the digital data of the time-dependent cellular structure (shape and size) and zellbedeckung directly under the new material in the material surfaces with defined distances from the new material, time-dependent, and 2 - dimensional ortsaufgelu00f6st is depicted.
