Abstract: An exemplary embodiment of the present disclosure provides an extended reality (XR) system comprising an autonomous robotic device and a user interface. The autonomous robotic device can be located in a physical environment. The user interface can be configured to display an XR environment corresponding to at least a portion of the physical environment and receive an input from the user based on the user's perception in the XR environment. The autonomous robotic device can be configured to perform an autonomous action based at least in part on an input received from the user.

Abstract: Methods, devices, and kits are provided for identifying, selecting, and/or manipulating live cells in a sample comprising a suspected mixed population of cells by subjecting the sample located in a first position to a linear gradient of a cellular stimulus to induce a change in a live cell sufficient to induce movement of the cell from a first position to a second position, wherein a dead cell, if present in the sample, is not induced to move to the second position in the presence of the cellular stimulus; and identifying or selecting the live cell in the second position.
