1. A vacuum manifold for filtration microscopy comprising:
a manifold top comprising a plurality of openings; and
a capture membrane positioned above and spaced apart from the manifold top, wherein the capture membrane is configured to deflect into contact with a surface of the manifold top when a negative pressure is applied to the plurality of openings.
