Effect of thermal annealing on a bilayer polyvinyl alcohol/polyacrylic acid electrospun hydrogel nanofibres loaded with doxorubicin and clarithromycin for a synergism effect against osteosarcoma cells
(Elsevier, 2021-08-02)
Polyvinyl alcohol/polyacrylic acid (PVA/PAA) bilayer hydrogel nanofibres were successfully fabricated by
electrospinning and physically crosslinked via heat treatment. The effects of the thermal annealing
process on the ...

(Athlone Institute of Technology, 2020-06)
New antimicrobial interventions are urgently required to combat rising global health and medical infection challenges. Here, an
innovative antimicrobial technology, providing price competitive alternatives to antibiotics ...
Treatment for the amelioration of persistent factors in complex anal fistula
(Springer, 2021-11-19)
Anal fistulae are abnormal hollow connections between the wall of the anal canal and the
perianal skin around the anus that have remained a burden on the medical sector for centuries.
The complexity of this disease is ...
Nanosuspension of pinhão seed coat development for a new high-functional cereal bar.
(Wiley, 2020-03-31)
The seeds from Araucaria angustifolia—commonly named as pinhão—are important culturally, and viable regional food from Brazil. Although now considered an endangered species, methods to increase the awareness of this tree ...
Antimicrobial PAA/PAH electrospun fiber containing green synthesized zinc oxide nanoparticles for wound healing
(MDPI, 2021-05-27)
Wound infections are the main complication when treating skin wounds. This work reports a novel antimicrobial material using green synthesized zinc oxide nanoparticles (ZnONPs) incorporated in polymeric fibers for wound ...
Upcycling biodegradable PVA/starch film to a bacterial biopigment and biopolymer
(MDPI, 2021-10-27)
Meeting the challenge of circularity for plastics requires amenability to repurposing post-use, as equivalent or upcycled products. In a compelling advancement, complete circularity for a biodegradable polyvinyl ...
Development of sustainable flexible packaging solutions using novel biodegradable and compostable polymer blends
(BioICEP, 2020-10-19)
