Aligned Chitosan-Polycaprolactone Polyblend Nanofibers Promote the Migration of Glioblastoma Cells

A comparison of the structure, thermal properties, and biodegradability of polycaprolactone/chitosan and acrylic acid grafted polycaprolactone/chitosan

The effects of replacing PCL with acrylic acid grafted PCL (PCL-g-AA) on the structure and properties of a PCL/chitosan composite were investigated. The properties of both PCL-g-AA/chitosan and PCL/chitosan were examined and compared using FTIR, H and C nuclear magnetic resonance (NMR), differential scanning calorimetry (DSC), and a biodegradation test. With PCL-g-AA in the composite, compatibi...

Measuring the Diameter of Nanofibers Extracted from Polyblend Fibers Using FCM Clustering Method

Covalent Capture of Aligned Self-Assembling Nanofibers

A great deal of effort has been invested in the design and characterization of systems which spontaneously assemble into nanofibers. These systems are interesting for their fundamental supramolecular chemistry and have also been shown to be promising materials, particularly for biomedical applications. Multidomain peptides are one such assembler, and in previous work we have demonstrated the re...

Aligned and random nanofibrous nanocomposite scaffolds for bone tissue engineering

Aligned and random nanocomposite nanofibrous scaffolds were electrospun from polycaprolactone (PCL), poly (vinyl alcohol) (PVA) and hydroxyapatite nanoparticles (nHA). The morphology and mechanical characteristics of the nanofibers were evaluated using scanning electron microscopy and tensile testing, respectively. Scanning electron microscopy revealed fibers with an average diameter of 123 ± 3...

Statistical Optimization of Production Conditions of Polycaprolactone-Chitosan-Curcumin Particles

Curcumin is an herbal plant with great therapeutic applications. Although it is useful in treating several diseases, its low solubility in water and low bioavailability in living systems are limiting factors in using curcumin as a medicine. One way to overcome these shortcomings is the production of curcumin micro/nano particles. In this research, the particles of curcumin loaded with polycapro...
