Abstract

Enzyme-mediated poly(gallic acid) crosslinked to carboxymethylcellulose toward a novel material for skin tissue engineering.

Development of an antimicrobial and antioxidant hydrogel/nano-electrospun wound dressing

“…Additionally, the hydrophobic PCL electrospun ber mats serve as an additional diffusion barrier to decrease the effective diffusion coefficients, thus reducing hydrogel swelling and water penetration rates as previously demonstrated by Han et al 55 Of note is that the PGAL also reduces the constant k, which might be ascribed to the drastic reduction of the swelling behavior for CMC when crosslinked to this polyphenol, in agreement to the previous study, 29 thereby the swelling is abated up to 90%. Noteworthy, the inuence of PGAL is also evidenced by the mean release time (T 1/2 ), which increases signicantly.…”

“…Comparing this spectrum with that for PGAL reported elsewhere, 29 where the carboxyl carbon signal appeared at d ¼ 177 ppm, this signal is now shied to a higher eld (165. carboxyl group of PGAL to yield the S2 connectivity through the S2-TS transition state. Fig.…”

“…28 The radical scavenging capacity in PGAL, along with its high solubility in physiological media, null cytotoxicity, electric semi-conductivity and high thermal and photostabilities are promising characteristics for application in wound dressing. [28][29][30][31] We produce scaffolds of nanobres of the enzymatic PCL graed with PGAL, as a nanocomposite dressing with antioxidant capacity composed of an antimicrobial hydrogel loaded into a nano-electrospun bre. The hydrogel network is formed by sodium carboxymethylcellulose (CMC) loaded with clindamycin, which is a broad-spectrum antibiotic for the treatment of infections of the bones, skin, so tissues and wounds and can be used to treat penicillin-allergic patients.…”

Biopolymeric Fibrous Aerogels: The Sustainable Alternative for Water Remediation

“…These features allow tuning its interaction with other polymers, nanoparticles, and small molecules [ 36 ]. The mechanical properties, pore size, and adsorption capacity of cellulose-derived materials depend largely on their crystalline state and processing method [ 31 , 37 ].…”

Electroanalysis of Gallic and Ellagic Acids at a Boron‐doped Diamond Electrode Coupled with High‐performance Liquid Chromatography

“…There was a decrease of the peak current and a shift of the peak potential towards more positive potentials for the five repeated CV waves (Figure 1a). This behavior could be attributed to the formation of electro inactive species to block the electrode surface including the possible formation of polygallic acid [17]. The anodic current corresponding to GA oxidation increased linearly with the square root of the scan rate (data not shown) indicating that the oxidation is a diffusion-controlled process at the electrode surface.…”
