The first use of electrospun nanofibrous membranes as highly responsive fluorescence quenching-based optical sensors for metal ions (Fe3+ and Hg2+) and 2,4-dinitrotoluene (DNT) is reported. A fluorescent polymer, poly(acrylic acid)−poly(pyrene methanol) (PAA−PM), was used as a sensing material. Optical chemical sensors were fabricated by electrospinning PAA−PM and thermally cross-linkable polyu...

Abstract Background Most of the natural extracellular matrix (ECM) is a three-dimensional (3D) network structure micro/nanofibers for cell adhesion and growth 3D. Electrospun fibers distinctive mimicked 2D ECM, however, it impossible to simulate 3D ECM because longitudinal collapse continuous micro/nanofibers. Herein, electrospun micro/nano-fibrous sponge was fabricated via electrospinning, hom...

Humidity indicators based on composite polyamide 66/cobalt chloride (PA66/CoCl2) nanofibrous membranes (NFMs) were successfully fabricated by electrospinning. A series of NFMs with various weight percentage of CoCl2 to PA66 were prepared, and their humidity sensitivity based on color changing and quartz crystal microbalance (QCM) were studied. Due to the color change property of cobalt chloride...

Large-strain elastic superhydrophobicity is highly desirable for its enhanced use performance and functional reliability in mechanically dynamic environments, but remains challenging to develop. Here we have, for the first time, proven that an elastic fibrous membrane after surface hydrophobization can maintain superhydrophobicity during one-directional (uniaxial) stretching to a strain as high...

Biotin has been successfully incorporated into polylactic acid (PLA) nanofibers through electrospinning to prepare membrane substrates for biosensors based on biotin–streptavidin specific binding. Biotin incorporated PLA nanofiber membranes were characterized with scanning electron microscopy (SEM), electron probe microanalysis (EPMA), and confocal microscopy. Under optimized conditions, small ...

Molecularly imprinted nanoparticles were encapsulated into polymer nanofibers with a simple electrospinning method. The composite nanofibers form non-woven mats that can be used as affinity membrane to greatly simplify solid phase extraction of drug residues in analytical samples. Upward 100% of propranolol-imprinted nanoparticles can be easily encapsulated into poly(ethylene terephthalate) nan...

The increase of antibiotic resistant microorganisms urged the development and synthesis of novel antimicrobial biomaterials to be employed in a broad range of applications, ranging from food packaging to medical devices. This work describes the production and characterization of a protein-based electrospun fibrous membranes bearing antimicrobial properties. Its composition is exclusively compri...
