There are many paper manuscripts and leather artifacts in different locations in Egypt (museums, libraries and etc.). Some of these locations are in improper conditions. According to that, some stains derived from different sources can be found on the surface of these materials. These stains are considered one of the most important problems that façade the conservators. In archaeological field, enzymes are used alone for removing stains. The aim of this paper is to focus on the role of some nanoparticles to enhance the activity of enzymes for removing stains more than being used alone. This study concludes that the use of nanoparticles with enzymes have high stability in a wide range of temperature and pH, compared to free enzymes. They benefit from the properties of nanoparticles such as size, shape, structure and their high catalysis capacity biocatalysts enzymes.
