System for detection using an array of cells expressing odorant receptors

摘要

Provided herein are arrays, devices, systems, and methods for detecting compounds such as odorant compounds. The arrays, devices, systems, and methods described herein can provide a pattern of electrical signals so that the presence or probability of presence of a given compound or mixture of compounds can be determined A pattern can be associated with the given compound or mixture of compounds. Cells expressing odorant receptors can be present in an array of chambers, each chamber measuring cells that have been modified to express a unique odorant receptor profile and electrical signals in the cells. And an electrical component configured as described above.
