What action can an unsecured creditor take in Howard County against a Corporation to help Secure a debt?

I have funded the operation of a corporation that operates in Howard County, Maryland. It is a sub-s Corporation that is incorporated in the State of Delaware. I have provided funding for several years to help the company meet its payroll and other expenses. I am not a shareholder or on the board of directors. I have deposited money directly into the company account and havecancelled checks as proof as well as several employees of the corporation that have witnessed this.
