Fiber scaffolds containing fibers of two unique compositions were obtained using the DS electrospinning apparatus. Macroscopically, the scaffold was a conformable and resilient structure having ultraflne cloth appearance. Fluorescence microscopy of the scaffold, which contained one fiber doped with Texas Red and another fiber without Texas Red, showed homogenous distribution of the two fibers (Figure 55.6). One can observe two larger diameter fibers One of which is clearly fluorescent (Fiber 1) and another which is not fluorescent (Fiber 2). 

The DS electrospinning apparatus could be used to electrospin a hybrid mesh of materials of varying degradation rates, mechanical properties, or chemical functionality. Here, the technique was used to create a mesh where one fiber was loaded with an antibiotic and another fiber was loaded with an anesthetic.
