) was found to primarily affect the internal structure of the fabric at the nano scale, whilst water as well as cell culture medium contact angles were dramatically decreased. Nearly no cytotoxic response (> 90% cell viability) was observed when L929 mouse fibroblasts were cultured in contact with electrospun peptide loaded samples. This novel nanofibrous architecture may be the basis for an interesting material platform for e.g. hard tissue repair, in light of the presence of the self assembled P 11 8 in the PCL fibrous structure.

“…However, the strong hydrogen bond formation of nylon 6 nanofibers and some ionic groups in cotton fabrics are confirmed from the FTIR spectra. Figure 5(b) and 5(c) show that the CH 2 bond along with amide I and III peaks take respectively place at 1652 (amide I), 1202, 1271 and 1363 cm −1 in N6C fabrics [6]. The peaks at 486 cm −1 in Fig.…”

“…Nanometal oxides incorporated into textile fabrics can improve their multifunctional properties such as flame retardancy, UV protection, self-cleaning, antistatic and antimicrobial activities [3]. Although polymeric materials used in textile fabrics can enhance their functional properties, polymeric nanofibers were used as a protective barrier on the textile fabrics for many applications such as wound dressing, air filteration, tissue scaffold, sensors, and fire retardancy [4][5][6][7].…”

Magnesia (MgO) nanoparticles were produced from magnesite ore (MgCO3) using ball mill. The crystalline size, morphology and specific SSA were characterized by X-ray diffraction analysis, transmission electron microscopy and Brunauer-Emmett-Teller method, respectively. MgO nanoparticle-incorporated nylon 6 solutions were electrospun to produce nanofiber mats. Surface morphology and internal structure of the prepared hybrid nanofiber mats were examined by scanning electron microscopy and high-resolution transmission electron microscopy, respectively. The fire retardancy and antibacterial activity (Staphylococcus aureus and Escherichia coli) of coated fabrics made from MgO/nylon 6 hybrid nanofiber are better than those from nylon 6 nanofiber.

“…In the IR spectrum of pristine nylon fiber, as shown in Fig. 4c, the intense amide I and II bands at 1638 cm -1 and 1553 cm -1 are observed, whereas the peaks at 1369 cm -1 and 1264 cm -1 correspond to the amide and CH 2 wagging [29]. In the case of NFs/nylon fiber, except for the similar characteristic peak with nylon fiber, the peak at 845 cm -1 was correlated with the rocking of CH 2 vibration [30], suggesting that the PVA-co-PE nanofibers was successfully coated on the nylon surface.…”

Fiber organic electrochemical transistors (FECTs) based on polypyrrole and nanofibers have been prepared for the first time. FECTs exhibited excellent electrical performances, on/off ratios up to 10(4) and low applied voltages below 2 V. The ion sensitivity behavior of the fiber organic electrochemical transistors was investigated. It exhibited that the transfer curve of FECTs shifted to lower gate voltage with increasing cations concentration, the sensitivity reached to 446 μA/dec in the 10(-5)-10(-2) M Pb(2+) concentration range. The ion selective properties of the FECTs have also been systematically studied for the detection of potassium, calcium, aluminum, and lead ions. The devices with different cations showed great difference in response curves. It was suitable for selectively monitoring Pb(2+) with respect to other cations. The results indicated FECTs were very effective for electrochemical sensing of lead ion, which opened a promising perspective for wearable electronics in healthcare and biological application. Graphical Abstract The schematic diagram of fiber organic electrochemical transistors based on polypyrrole and nanofibers for ion sensing.
