Abstract Cellulose has been intensively investigated for biomedical applications, because of its excellent properties, like biodegradability, biocompatibility, abundant availability renewable resources and cost-effectiveness. Among all sources cellulose, marine macroalgae or seaweeds, are acquiring tremendous attention, due to their high around the world. Moreover, atypical proliferation some exotic species represents a serious problem ecosystems, since accumulation threatens native oceanic...
Cellulosic fibre-based smart materials exhibiting multiple capabilities are getting tremendous attention due to their wide application areas. In this work, multifunctional flax fabrics with piezoresistive response were developed through the combined functionalization silver (Ag) and zinc oxide (ZnO) nanoparticles (NPs). Biodegradable polyethylene glycol (PEG) was used produce AgNPs, whereas ZnONPs synthetized via a simple low-cost method. Flax without NPs characterized by Ground State...
Several studies have demonstrated that administration of doxorubicin (DOXO) results in cardiotoxicity, which eventually progresses to dilated cardiomyopathy. The present work aimed evaluate the early myocardial changes DOXO-induced cardiotoxicity. Male New Zealand White rabbits were injected intravenously with DOXO twice weekly for 8 wk [DOXO-induced heart failure (DOXO-HF)] or an equivolumetric dose saline (control). Echocardiographic evaluation was performed, and samples collected cellular...
Due to the prevalence of COVID-19 pandemic, demand for disposable facemasks has become a global issue. Unfortunately, use these products negative effects on environment, and therefore, biodegradable materials is powerful strategy overcome this challenge. Aligned with concept, in work, were developed using poly(ε-caprolactone) (PCL) polymer cotton natural fibers. The filter layer was produced an electrospinning technique, since electrospun membranes present remarkable characteristics air...
A thermoplastic starch (TPS) was produced, starting with potato starch, glycerol and acetic acid, to shape it in films of thickness around 100 microns. To TPS iron waste filing particles, the amount 12% weight were introduced different modalities: as received, reduced size by use a mortar, after treatment hydrochloric removal acid. Morphological studies carried out optical scanning electron microscopy illustrated that dispersion filings not optimal, though some improvement observed dimension...
Core–shell nanofibers loaded with porphyrin were produced to act as localized DDS for treating cervical cancer using PDT. Porphyrin-loaded electrospun showed a higher phototoxic effect against tumor cells compared non-tumor ones.
Multifunctional fibrous systems were developed within this research work, giving special importance to the electrical conductivity and antibacterial activity. The functionalization of several natural fibres (jute, sisal, coir, flax cotton) with silver nanoparticles (Ag NPs) was successfully achieved using a sustainable eco-friendly method, namely polyethylene glycol (PEG) reduction. FESEM images, GSDR ATR-FTIR analysis show that Ag NPs incorporated onto surface. resistivity values obtained...
In this work, natural-based and biodegradable nanofibers were produced by electrospinning for drug delivery wound dressing applications, using gelatin (Gel), chitosan (CS), cellulose nanocrystals (CNC) natural propolis extract. The polymeric formulations parameters optimized, resulting in the development of Gel/CS with mean diameters 97 nm. CNC successfully introduced into optimized solution viscosity conductivity values recorded. developed characterized FESEM, ATR-FTIR, TGA WCA....
