Binding and Inactivating Coronavirus with Clinoptilolite

Natural zeolites are known to bind various bacteria and viruses. Researchers hypothesised that clinoptilolite can also bind members of the Coronaviridae family.

Results showed that the addition of 0.01% PCT purified clinoptilolite to a HCoV-229E suspension containing 16,000 PFU per ml resulted in an 87% reduction of the virus concentration.

Results suggest that purified clinoptilolite in a liquid or gel suspension may represent a natural, safe, and effective candidate for the development of a medical device destined to reduce SARS-CoV-2 infectivity and virus spread in patients.
