“…CPs also tend to suffer from poor mechanical properties, for example polyprrole has been reported to have poor ductility, and is brittle (67). Therefore, although CP films can be cast onto substrates, it is not generally possible to produce robust CP films with sufficient mechanical integrity to be free-standing.…”

The growing needs for analytical devices requiring smaller sample volumes, decreased power consumption and improved performance have been driving forces behind the rapid growth in nanomaterials research. Due to their dimensions, nanostructured materials display unique properties not traditionally observed in bulk materials. Characteristics such as increased surface area along with enhanced electrical/optical properties make them suitable for numerous applications such as nanoelectronics, photovoltaics and chemical/biological sensing. In this review we examine the potential that exists to use nanostructured materials for biosensor devices.By incorporating nanomaterials, it is possible to achieve enhanced sensitivity, an improved response time and smaller size. Here we report some of the success that has been achieved in this area. Many nanoparticle and nanofibre geometries are particularly relevant, in this paper however we specifically focus on organic nanostructures, reviewing conducting polymer nanostructures and carbon nanotubes.

“…Electroconductive polyester fibers have received increasing attention over the last few years, because of their potential applications in electromagnetic shielding clothing [3], medical therapeutics devices [4], supercapacitors [5,6], chemical and biological sensors [7][8][9][10]. Therefore, it is desirable to synthesize conductive polypyrrole (PPy) as thin layers on the PET fabrics by chemical method or by electrochemical method [11][12][13].…”

A simple and effective surface modification of polyester fabrics with sulfuric acid to improve the interfacial deposition of polypyrrole was presented in our work. A range of sulfuric acid concentrations were analyzed by studying water contact angle. Effect of sulfuric acid modification on the deposition of polypyrrole was investigated by sheet resistance and color depth of fabric samples. Polyester fabrics coated with polypyrrole layer were confirmed by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), X-Ray diffraction spectra (XRD), Fourier transform infrared spectroscopy (FTIR). XPS showed that sulphur containing functional groups were obviously appeared on the polyester fiber surface after modification, which were advantageous to promote the deposition of polypyrrole onto polyester fabrics. The improved deposition increased electrical conductivity of fabric samples.

“…There is a considerable interest in the development of advanced continuous fibers with nanoscale diameters. These fibers with smaller pores and higher surface area have enormous applications such as scaffolds for tissue engineering or as drugdelivery systems [15,16], sensor, laser and switchable textiles [17][18][19][20], wearable electronics [21][22][23] and wound healing [24,25]. However, conventional mechanical fiber spinning techniques cannot produce fibers with diameters smaller than about 2 μm.…”

A simple and facile approach to fabricate PVP fibers by wheel-spinning technique was investigated. Poly(vinyl pyrrolidone) sol (PVP, M w =1,300,000, 6-14 w% in ethanol) was used as the candidate polymeric material. It was demonstrated by a rotating wheel with the speeds of 18.84, 15.70 and 12.56 m/s, respectively, PVP fibers can be drawn with diameters ranging from under 200 to over 2 µm and controlled by changing the rotating speed and sol concentration. The morphologies of the wheel-spinning fibers were observed by electronic scanning microscopy (SEM). The nanofibers obtained by this technique are long, straight and smooth, and the fabricated apparatus is simple.
