Abstract
A method for using a natural attapulgite is disclosed. The method includes using the natural attapulgite as a natural nano mineral enzyme. The results of the examples show that the natural attapulgite has peroxidase-like activity, catalase-like activity or superoxide dismutase-like activity, and good biocompatibility. Compared with protease, the natural attapulgite has the advantages such as large reserves, easy to obtain, low cost, high temperature resistance and wide range of pH value. Compared with a developed artificial nano enzymes, the natural attapulgite further has the advantages such as multi-function, natural non-toxic (from nature, no heavy metals), good biocompatibility, easy to obtain, no complex processing, and huge surface area which provides a place for cell growth and proliferation.
