As of my last knowledge update in January 2022, I don't have specific information about a company named "Serendix" and its technology. It's possible that there have been developments or announcements since then. To find the most accurate and up-to-date information about Serendix's technology and its availability in the U.S., I recommend checking the company's official website, press releases, or contacting the company directly if they have provided any public contact information.
Additionally, keep an eye on relevant news sources and industry publications for potential updates on Serendix and its technology. Companies often make announcements about product releases, partnerships, or market availability through these channels.
