Nanofiber Solutions (NFS) develops and markets electrospun nanofiber scaffolds for cell culture, drug development, and tissue engineering applications including the first in man synthetic nanofiber trachea.  We offer a variety of configurations ranging from multiwell culture plates to larger commercial bioreactor configurations to custom designed tissue scaffolds. Historically, cell culture has been performed on flat, tissue culture polystyrene (TCPS) because it is cheap, optically clear, and many cells grow well on it.  In reality, however, living organisms are made up of an extracellular matrix (ECM) that presents both aligned physical structure and mechanical support to the cells. Adherent cells are complex, self-sustaining units that require ECM anchorage to proliferate and undergo normal differential function. Nanofiber Solutions seeks strategic partners well established in tissue engineering and medical implants to help us bring other applications of this platform technology to market.  Other applications include small and large diameter blood vessels, esophagus, colon, intestine, cartilage, wound healing and hernia repair.
