Fabrication of poly(vinyl acetate)/polysaccharide biocomposite nanofibrous membranes for tissue engineering

Application of response surface methodology to tailor the surface chemistry of electrospun chitosan-poly(ethylene oxide) fibers

“…The potential of the predictive RSM to tailor physical and biological characteristics of chitosan non-wovens has been demonstrated using the example of the membrane zeta potential. The amount of nitrogen atomic surface content has been shown to positively correlate with the measured zeta potential, which is known to be linked with the cell adhesion and proliferation (Chen et al 2011;Jeong et al 2013;Croisier et al 2014) as well as with the antimicrobial activity (Chang et al 2015;Ceylan et al 2017) exhibited by the membrane. Although the model is applicable only under the experimental conditions inside the design space, the potential of RSM in modeling the surface properties of chitosan fibers as an outcome of a multi-parameter process is promising and could pave a way towards rationally designed drug delivery systems or tissue engineering applications based on chitosan non-wovens.…”

Room-temperature ppb-level trimethylamine gas sensors functionalized with citric acid-doped polyvinyl acetate nanofibrous mats

“…58 Meanwhile, for the FTIR spectrum of the PVAc sample, the characteristic peaks of O-H and CQO stretching vibration modes were detected at the peaks of 3425 and 1735 cm À1 , respectively. 59 By combining the CA dopant with the PVAc nanofibers, it was expected that the characteristics of these two materials should be jointly apparent in the spectra. This has been proven from our measurements, where the peaks observed in the spectra of PVAc/CA nanofibers were similar to those in the spectrum of the PVAc nanofiber.…”

Novel chitosan-poly(vinyl acetate) biomaterial suitable for additive manufacturing and bone tissue engineering applications

“…Additionally, strong vibration bands at 1232 cm −1 and 1014 cm −1 were observed due to C-O stretching mode of ester groups. 27 For CS, typical spectral bands of 3358 cm −1 and 3281 cm −1 correspond to the O-H and N-H stretching. Spectral bands at 2916 cm −1 and 2862 cm −1 were observed as a result of symmetric and asymmetric stretching of C-H.…”

“…20 Additionally, PVAc has also been used as a component in studies on biomaterials for biomedical applications. [21][22][23][24][25][26] Scaffolds that combine CS and PVAc are not commonly used in tissue engineering, however, Jeong et al 27 fabricated nanofibrous membranes using electrospinning. Comparing PVAc membranes and PVAc-CS membranes, the addition of CS improved cell attachment.…”
