Title:
ANTIBACTERIAL AGENT, ANTIVIRAL AGENT, AND USES OF THESE
Document Type and Number:
WIPO Patent Application WO/2023/243525
Kind Code:
A1
Abstract:
The present invention is an antibacterial agent or an antiviral agent that is characterized by containing a silver-bonded fucoidan in which silver is bonded to a sulfate group of fucoidan. As a result, it is possible to provide an antibacterial agent and an antiviral agent that have fucoidan as a base and are highly effective.
