Bhattarai et al. developed a novel biodegradable electrospun membrane as a scaffold for tissue engineering. A nanofibrous matrix of poly(p-dioxanone-co-L-lactide)-block-poly(ethylene glycol) (PPDO/PLLA-b-PEG) copolymer was evaluated for cell proliferation and its morphology of cell-matrix interaction. The electrospun structure composed of fibers with an average diameter of 380 nm, medium pore size 8 mm, porosity greater than 80% and mechanical strength of 1.4 MPa is favorable for cell-matrix interaction [39]. 

Intensive research effort has been focused on using nanoscale structures to significantly improve the performances (sensitivity, selectivity, response and recovery speed) of the SAW sensors. Liu et al. [39] reported that dynamic chemical vapor SAW sensors have been developed by depositing electrospun polyethylene oxide nanofibrous membranes on the surface of ST-cut quartz the response time of the sensors was 5 min (Fig. 11.2a). Lin [42] constructed a SAW humidity sensor by casting polyaniUne/poly(vinyl butyral) nanofibers on SAW resonator the as-prepared sensor could detect 0.5 % relative humidity in 1 s. Electrospun poly(vinyl pyrrolidone) (PVP)/LiTa03 composite nanofibrous membranes were coated onto the surface of SAW electrode to assay H2 the results indicated that the sensors sensitivity, response time, and recovery time could be remarkably improved and reached 1 %, 120, and 200 s by regulating the electrospinning parameters [43].
