Abstract: Optoinjection method for transiently permeabilizing a target cell by (a) illuminating a population of cells contained in a frame; (b) detecting at least one property of light directed from the frame; (c) locating a target cell by the property of light; and (d) irradiating the target cell with a pulse of radiation.

Abstract: The invention provides methods for purifying one or more cells based on the level of one or more products secreted by the cells.

Abstract: This invention provides a method and apparatus for selectively identifying, and targeting with an energy beam, specific cells within a cell population, for the purpose of inducing a response in the targeted cells. Using the present invention, every detectable cell in a population can be identified and affected, without substantially affecting non-targeted cells within the mixture.

Abstract: The invention relates to methods and apparatuses for introducing and releasing substances into and out of cells, and more specifically to methods and apparatuses for transiently permeabilizing a living cell so that any one or more of a variety of substances, such as ions, proteins, and nucleic acids, can be loaded into or released out of the cell.

Abstract: The invention provides an apparatus for electromagnetically affecting a particle of interest in a specimen. The apparatus includes (a) a stage capable of supporting the specimen; (b) a detector including at least one camera, wherein the detector is capable of resolving a particle of interest within the specimen; (c) a means for locating the particle of interest in three dimensions; (d) a means for focusing electromagnetic radiation to a focal volume within the specimen; and (e) a means for adjusting the relative positions of the stage and electromagnetic radiation focusing means, thereby positioning the particle of interest within the focal volume.
