  • Patent number: 11662564
    Abstract: 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, and 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.
