Fabrication of novel nanofiber scaffolds from gum tragacanth/poly(vinyl alcohol) for wound dressing application: In vitro evaluation and antibacterial properties

Fractionation and some physicochemical properties of almond gum (Amygdalus communis L.) exudates

“…The peak at 2855 cm À1 is assigned to the symmetric stretching vibrations of CH 2 efunctional groups in the three cases while the one for the whole gum is more specific than those of the water soluble and water insoluble fractions (Ranjbar-Mohammadi et al, 2013). The peaks at 1602 and 1601 cm À1 may be attributed to the asymmetrical stretching of carboxylate groups or to the intramolecularly bound water (Fadavi et al, 2014).…”

“…The peak at 1375 cm À1 could be ascribed to the bending group of the symmetric eCH 3 (Derrick, Stulik, & Landry, 1999, Chapter 2). Those at 1023, 1024, and 1026 cm À1 are due to the stretching vibration of alcoholic groups (Ranjbar-Mohammadi et al, 2013) and those in the range of 1500 cm À1 and 500 cm À1 represent the carbohydrate fingerprints (Alijani, Balaghi, & Mohammadifar, 2011). The peaks lying between 1200 and 1000 cm À1 belong to the complex bonds of CeO and CeC.…”

Physio-chemical and antibacterial characteristics of pressure spun nylon nanofibres embedded with functional silver nanoparticles

“…Nanofibrous structures as an antimicrobial scaffold provide higher cell adhesion than other structures [7]. They have been also used in wound dressing and healing where these scaffolds possess more homogeneity, oxygen penetration and prevent infections and dehydration [8]. Nylon polymer nanofibres exhibit excellent mechanical properties, such as toughness, and high tensile strength and have been adopted to make various composites [9][10][11].…”

Electrospun nanofibers of polyCD/PMAA polymers and their potential application as drug delivery system

“…Electrospinning is a simple and versatile technique that is capable of manufacturing continuous fibers with diameters ranging from micrometers down to several nanometers by applying strong electric fields, and this technique can be a useful alternative for pharmaceutical applications in which drugs incorporated in a polymeric solution or melt are used [11][12][13]. Fibers produced by electrospinning can combine PROP possesses physicochemical properties such as high solubility in water (50 mg mL −1 ), a short half-life (3-5 h) and a low molecular weight (295.81 g mol −1 ) that make it a suitable candidate for incorporation in DDS that use other routes of administration instead of oral administration [21].…”
