Electrohydrodynamic (EHD)-inkjet printing is a novel high resolution inkjet printing technology with the advantages of being a maskless, non-contact, direct-write and additive process. Its printing resolution exceeds by about two orders of magnitude in comparison to the conventional inkjet printing systems. It is used in the field of micro/nano manufacturing for patterning of large class of mat...

conventional transdermal drug delivery systems (tdds) have been designed for drug delivery through the skin. these systems use the permeability property of stratum corneum, the outermost surface layer of the skin. applying polymeric micro and nanofibers in drug delivery has recently attracted great attention and the electrospinning technique is the preferred method for polymeric micro-nanofiber...

a new natural and environmental friendly wound dressing was introduced for the first time that was prepared by electrospinning method. this new wound dressing has chitosan base, and poly (ethylene oxide) was added as co-spinning agent to improve spinnability of chitosan. moreover, thyme extract as a natural antibacterial additive was introduced in the as electrospun nanofibers scaffold in order...

objective(s): in this work, electrospun nanofibers were explored as drug delivery vehicles using tetracycline as a model drug.  nanocomposite fibers including chitosan (cs)/poly (ethylene oxide) (peo) and antibiotic were successfully prepared using electrospinning. cs blended with peo considering a weight ratio of (90/10), and then, nanofibrous samples were successfully electrospun from their a...

textile wastewaters due to the toxic effects of dyestuffs and other organic compounds and their stability toward light and oxidizing agents have led to an environmental problem. several treatment methods for dye removal have been investigated. membrane process is one of the simplest and most effective methods for dye removal from industrial wastewaters. electrospun nanofibrous membranes have hi...

catalytically graphitized electrospun carbon nanofibers adorned uniformly with fine nickel nanoparticles were successfully prepared. the procedure was based on the electrospinning technique and the use of nickel precursor to create both graphitized nanofibers and nickel nanoparticles under a relatively low-temperature heat treatment. the x-ray diffraction and raman results clearly proved cataly...

amodified technique is designed to prepare aligned nanofibers to challenge the existing limitations in collecting methods of nanofibers such as, thickness of collected layer, alignment and productivity of nanofibers. collecting and simultaneously heating of the aligned nanofibers were carried out by using a rotating drum fixed on top of syringe needles and applying hot air flow. this electrospi...

BACKGROUND Electrospinning is a simple and effective method for fabricating micro- and nanofiber matrices. Electrospun fibre matrices have numerous advantages for use as tissue engineering scaffolds, such as high surface area-to-volume ratio, mass production capability and structural similarity to the natural extracellular matrix (ECM). Therefore, electrospun matrices, which are composed of bio...

Electrospun nanofiber scaffolds have been shown to accelerate the maturation, improve the growth, and direct the migration of cells in vitro. Electrospinning is a process in which a charged polymer jet is collected on a grounded collector; a rapidly rotating collector results in aligned nanofibers while stationary collectors result in randomly oriented fiber mats. The polymer jet is formed when...
