However, the process developed by Wang and his co-workers to make their sponge uses formaldehyde(甲醛), a highly poisonous chemical,and there were small amounts of this in the sponge itself.When it comes to dealing with microplastic pollution in the ocean, Alice Horton at the United Kingdom...
The specimen is placed ina liquid fixing agent (fixative) such as formaldehyde solution (formalin). This will slowly penetrate the tissue causing chemical and physical changes that will harden and preserve the tissue and protect it against subsequent processing steps. What is histology used for?
