Waveguide-based side-illumination technique for muse microscopy and associated histology cassettes

During operation of the system, a sample of the biological material is placed against a surface of a waveguide, which is comprised of a UV-transparent waveguide material. Then, the system launches UV light from a UV light source via side-illumination into an input end of the waveguide, wherein a launch angle for components of the UV light is greater than a critical angle between the waveguide material and air, so that the UV light propagates through the waveguide via total internal reflection to reach the sample. The launch angle is also less than a critical angle between the waveguide material and the sample, so that when the UV light reaches the sample, the UV light escapes the waveguide through refraction to illuminate the sample. Finally, an imaging mechanism located on an opposite side of the waveguide from the sample captures an image of the illuminated sample.

A method for filtration microscopy includes the steps of providing a vacuum manifold including a manifold top having a plurality of openings, and a capture membrane positioned above and spaced apart from the manifold top; applying sample drops to sample spots on the membrane, the sample spots positioned above the plurality of openings; applying a negative pressure to the openings such that the capture membrane contacts a surface of the manifold top; and optically imaging particulates on the capture membrane.

PARAFFIN SHIELD COATING FOR MICROSCOPE SLIDE
20230280578 · 2023-09-07 ·

A shield coating on a microscope slide, and particularly a selective application of a paraffin layer to shield biomaterials and inorganic chemical deposits from microbial attack and oxidation, aid more particularly, an application of a paraffin layer on a microscope slide as an exposure shield over deposited biomaterial reactive targets. The paraffin shield layer blocks the biomaterial and chemical targets from exposure, which may lead to degradation due to oxidation and provides resistance to fungal growth, while using the existing stain processing steps to remove the paraffin from the shield and co-resident tissue section.
