Described herein are devices, compositions and methods relating to the production of high basis weight, non-woven nanofiber polymer fabrics. In certain embodiments, described herein are modifications to free-surface, needle-less or nozzle-less electrospinning devices that permit the production of such high basis weight, non-woven nanofiber polymer fabrics. Also described are the fabrics themselves and the fabrics including one or more biologically active agents to be released upon contact with a biological tissue. Such fabrics can incorporate biologically active agents in various combinations that permit, for example, burst and/or sustained release kinetics of one or more, preferably two or more biologically active agents. |
