Methods, compositions and kits for determining the developmental potential of one or more embryos or pluripotent cells and/or the presence of chromosomal abnormalities in one or more embryos or pluripotent cells are provided. These methods, compositions and kits find use in identifying embryos and oocytes in vitro that are most useful in treating infertility in humans.

A beam device, in particular a particle beam device, for analyzing an object is provided, as well as a system comprising a particle beam device and an optical microscope for optically analyzing an object. The beam device simplifies the exchange and reduces the time of the exchange of objects to be examined. The beam device includes at least one beam generator that generates a beam, at least one objective lens that focuses the beam on an object arranged in a holding element. The objective lens comprises at least one connecting element. The holding element may be connected to the connecting element so that the holding element is removable from the connecting element for modification of the object. Alternatively, the holding element may be mounted to a beam column.

Exemplary embodiments provide solid-state microscope (SSM) devices and methods for processing and using the SSM devices. The solid-state microscope devices can include a light emitter array having a plurality of light emitters with each light emitter individually addressable. During operation, each light emitter can be biased in one of three operating states including an emit state, a detect state, and an off state. The light emitter can include an LED (light emitting diode) including, but not limited to, a nanowire based LED or a planar LED to provide various desired image resolutions for the SSM devices. In an exemplary embodiment, for near-field microscopy, the resolution of the SSM microscope can be essentially defined by the pitch p, i.e., center-to-center spacing between two adjacent light emitters, of the light emitter array.
