I agree with Michael on filing a US patent provisional, especially if you intend to license the material/chemistry/technology and want to have the IP protected. Most academic institutions have a office of licensing and ventures which oversees tech transfer from research to external companies. Then can often fund the cost for the provisional, which gives you a year to gather supporting data, publications, and other information that will help your patent get reviewed, revised, and approved.
Prior to the provisional deadline, you will want to either reach out to companies that are open to taking on the patent costs and technology development, or more likely you will need reach out to VC funds to spin off the technology and pay the patent costs. And by you, I mean the office that regulates licensing, since they usually have the lawyers and writing team necessary to get all of the paperwork and fees organized.
The process can be slow, with some patents taking years for debating novelty and revisions, unless the technology is very convincing to be unique and promising. That’s why it helps to have a good paper trail to show the advances of your biomaterial.
