Abstract (en)

[origin: WO2018228508A1] A shield coating on a microscope slide is provided. Particularly, the selective application of a paraffin layer to shield biomaterials and inorganic chemical deposits from microbial attack and oxidation is provided. More particularly, the application of a paraffin layer on a microscope slide as an exposure shield over deposited biomaterial reactive targets is also provided. 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.
