Published: Jan. 15, 2025

As sex pheromones are environmentally friendly and specific, they often used to monitor control oriental fruit moths (OFMs). Currently, non-biodegradable polymers commonly employed as carriers prepare controlled pheromone release systems for plant protection. Electrospinning is a relatively simple technique preparing biodegradable nanofibers that allows the of pheromones. This study aimed develop system combination OFM codlemone via electrospinning, in which was synergist pheromone. New combined from colding were developed using electrospun polycaprolactone (PCL), cellulose acetate (CA), polylactic acid (PLA). In indoor experiments, load ratio stability CA loaded with (CA-SP) superior those other two nanofiber types. field among all treatments, 10 mg CA-SP most attractive OFMs, its effective duration approximately 6 weeks. The optimum storage temperature -20 °C. Electrospun friendly, stable release. presents new could be beneficial monitoring OFMs. © 2025 Society Chemical Industry.

Electrospun Ethyl-p-Methoxycinnamate Loaded CS/PEG/PLA Nanofibers

AATCC Journal of Research, Journal Year: 2025, Volume and Issue: 12(1)

Published: Jan. 1, 2025

In this study, the characteristic properties and biological activities of electrospun nanofibers made polymers including chitosan (CS), polyethylene glycol (PEG), polylactic acid (PLA) loaded with 15% a natural anti-inflammatory analgesic agent, ethyl p-methoxycinnamate (EPMC), were reported. The morphological chemical characteristics fibers analyzed using scanning electron microscope Fourier transform infrared spectra, respectively. mechanical hydrophilicity also investigated. Research on release bioactive compound EPMC from in phosphate-buffered saline medium showed that about 70% was released after 24 h. significant effect evaluated via inhibition nitric oxide production RAW264.7 cells stimulated by lipopolysaccharide an IC 50 value 41.05 ± 1.75 µg/mL. Besides, exhibited anti-bacterial activity proved to be safe both vitro vivo. results suggested CS/PEG/PLA may potential candidate for developing biomedical products related inflammation.

Electrospun Cerium Oxide Nanoparticle/Aloe Vera Extract-Loaded Nanofibrous Poly(Ethylene Oxide)/Polyurethane Mats As Diabetic Wound Dressings

ACS Applied Bio Materials, Journal Year: 2024, Volume and Issue: 7(8), P. 5268 - 5278

Published: Aug. 2, 2024

Currently the prevalence of diabetic wounds brings a huge encumbrance onto patients, causing high disability and mortality rates major medical challenge for society. Therefore, in this study, we are targeting to fabricate aloe vera extract infused biocompatible nanofibrous patches facilitate process wound healing. Additionally, clindamycin has been adsorbed surface in-house synthesized ceria nanoparticles again used separately design web, as nanoceria can act good drug delivery vehicle exhibit both antimicrobial antidiabetic properties. Various physicochemical characteristics such morphology, porosity, chemical composition produced webs were investigated. Bacterial growth inhibition antibiofilm studies materials confirm its antibacterial efficacy against Gram-positive Gram-negative bacteria. An vitro release study confirmed that mat show sustained pattern (90% 96 h). The web containing loaded not only showed superior performance but also promoted greater contraction (95 ± 2%) diabetes-induced mice just 7 days. Consequently, it efficaciously lowers serum glucose level, inflammatory cytokines, oxidative stress, hepatotoxicity markers endorsed by various ex vivo tests. Conclusively, in-house-fabricated patch potential medicated suppository be treating proximate future.
