摘要： The present invention provides methods of making covalently crosslinked vinyl polymer hydrogels having advantageous physical properties, and covalently crosslinked vinyl polymer hydrogel compositions made by such methods, as well as articles of manufacture comprising such covalently crosslinked vinyl polymer hydrogel compositions. The physical properties of the produced hydrogels can be adjusted by varying controlled parameters such as the proportion of physical associations, the concentration of polymer and the amount of radiation applied. Such covalently crosslinked vinyl polymer hydrogels can be made translucent, preferably transparent, or opaque depending on the processing conditions. The stability of the physical properties of the produced vinyl polymer hydrogel can be enhanced by controlling the amount of covalent crosslinks.

摘要： Systems, devices, and methods are provided for assembling polymer-forming molecular components such that highly-structured arrays of polymer strands, such as collagen fibrils, are formed without the need for cells. A polymer nanoloom is designed to control the self-assembly of monomers into fibrils and related tissue constructs including ligament, tendon, cartilage, and bone. A nanoloom system comprises a polymer printhead, a temperature controller, and a movable substrate for polymer printing. A polymer printhead contains one or more nanoreactors that can control the assembly of collagen fibrils or other polymers on a nanoscale. Methods are provided for temperature-driven, enzyme-driven, and cholesteric assembly of collagen or other polymers into two- or three-dimensional tissue constructs.
