Abstract: The techniques described herein relate to systems, apparatus, articles of manufacture, and methods for gaze angle triggered fundus imaging. An example method includes detecting a pupil of a subject in a stereo image, controlling at least one actuator to align an imaging path of a fundus camera with the pupil after detecting the pupil in the stereo image, and capturing a fundus image of a retina of the subject at a gaze angle after determining that the pupil is oriented towards a target direction based on the gaze angle associated with the pupil in the image.

Abstract: Embodiments of the current disclosure are directed to systems, methods and apparatus for the multiplexed analysis of biological material. In some embodiments, the apparatus may comprise an assembly including a first frame including a plurality of first openings; a capture agent slide; and a channel membrane.
