“…This is particularly useful in some cases, such as PCs, where improved windproof properties of membranes are highly desired, or in wound dressing, where warding off aerosol particles and viruses is important. Furthermore, as the diameter of the nanofibers decreases, the specific surface area increases [27]; this, in turn, improves the sensing performance of nanofibrous membranes.…”

“…PU is a popular polymer that is used extensively in electrospinning processes [22,23,24]. This polymer has unique properties such as excellent hydrolytic stability, good mechanical properties, and resistance to chemicals, microorganisms and abrasion [25,26,27]. PU has hydrophobic properties and lends well to nanofibrous structures with diameters ranging from 200 to 600 nm.…”

Nanofibrous-based pH sensors have shown promise in a wide range of industrial and medical applications due to their fast response time and good mechanical properties. In the present study, we fabricated pH-sensitive sensors of nanofibrous membranes by electrospinning polyurethane (PU)/poly 2-acrylamido-2-methylpropanesulfonic acid (PAMPS)/graphene oxide (GO) with indicator dyes. The morphology of the electrospun nanofibers was examined using scanning electron microscopy (SEM). The effect of hydrophilic polymer ratio and concentration of GO on the sensing response time was investigated. The sensitivity of the membranes was studied over a wide pH range (1–8) in solution tests, with color change measured by calculating total color difference using UV-vis spectroscopy. The membranes were also subjected to vapor tests at three different pH values (1, 4, 8). SEM results show the successful fabrication of bimodal fiber diameter distributions of PU (mean fiber diameter 519 nm) and PAMPS (mean fiber diameter 78 nm). Sensing response time decreased dramatically with increasing concentrations of PAMPS and GO. The hybrid hydrophobic/hydrophilic/GO nanofibrous membranes are capable of instantly responding to changes in solution pH as well as detecting pH changes in chemical vapor solution in as little as 7 s.

The aim of this systematic review is to evaluate the impact of personal protective equipment (PPE) on medical device use during public health emergency responses. We conducted a systematic literature search of peer-reviewed journals in PubMed, Web of Science, and EBSCO databases. Twenty-nine of 92 articles published between 1984 and 2015 met the inclusion criteria for the review. Although many medical device use impacts were reported, they predominantly fell into 3 categories: airway management, drug administration, and diagnostics and monitoring. Chemical, biological, radiological, and nuclear (CBRN)-PPE increased completion times for emergency clinical procedures by as much as 130% and first attempt failure rates by 35% (anesthetist) versus 55% (non-anesthetist). Effects of CBRN-PPE use depend on device, CBRN-PPE level, and clinician experience and training. Continuous clinical training of responders in CBRN-PPE and device modifications can improve safety and effectiveness of medical device use during public health emergency response.

“…[8] Nanofibers can also find applications in air filtration and protective clothing. [9][10][11] Electrospinning has been successfully and most commonly employed to produce nanofibers with controllable diameters. [12,13] In this method, fiber formation can be influenced by both electrospinning process [14] and solution parameters.…”

In this study, a biocompatible nanofiber is fabricated using Plantago ovata mucilage (POM) combined with polyvinyl alcohol (PVA), which is considered as a non‐toxic polymer. High quality nanofibers were produced by controlling the electrospinning parameters after selecting an appropriate solvent for the POM/PVA combination (12% PVA and 3% POM). Electrospinning parameters, including high voltage, distance from collector to tip, feed rate and POM to PVA proportion were optimized following preparation of an aqueous POM/PVA solution. Using the results of scanning electron microscopy, the optimized electrospinning conditions for producing POM/PVA nanofibers were determined (high voltage = 18 kV, distance = 15 cm, feed rate = 0.125 ml/hr, PMM/PVA = 50/50) and uniform nanofibers with an average diameter of 250 nm were produced. The POM/PVA nanofiber sample was evaluated by determining the mechanical strength, characterization of produced nanofiber morphology, and investigating the cell viability by applying MTT assay. The bands for both POM and PVA from FTIR results showed that the samples remained stable. The tensile strength results showed that blending POM with PVA solution enhanced the Young's modulus by factor of 3.2 (0.2 MPa to 0.64 MPa). The MTT analysis on POM/PVA cell lines proved that the produced nanofiber considerably enabled the cellular proliferation. Enhancement in these analysis indicated how POM‐based nanofibers is a promising scaffold for cell culture, drug delivery systems and food additives.
