Aloe vera mucilage loaded gelatin electrospun fibers contained in polylactic acid coaxial system and polylactic acid and poly(e-caprolactone) tri-layer membranes for tissue engineering.

Background: Polymeric electrospun mats have been used as scaffolds in tissue engineering for the development of novel materials due to its characteristics. The usage of synthetic materials has gone in decline due to environmental problems associated with their synthesis and waste disposal. Biomaterials such as biopolymers have been used recently due to good compatibility on biological applications and sustainability.

Nanocomposite Hydrogels Based on Poly(vinyl alcohol) and Carbon Nanotubes for NIR-Light Triggered Drug Delivery.

Photothermal nanocomposite hydrogels are promising materials for remotely triggering drug delivery by near-infrared (NIR) radiation stimuli. In this work, a novel hydrogel based on poly(vinyl alcohol), poly(vinyl methyl ether--maleic acid), poly(vinyl methyl ether), and functionalized multiwalled carbon nanotubes (MWCNT-f) was prepared by the freeze/thaw method. A comparative characterization of materials (with and without MWCNT-f) was carried out by infrared spectroscopy, differential scanning calorimetry, scanning electron microscopy, mechanical assays, swelling kinetics measurements, and photothermal analysis under NIR irradiation.

Study of Electrospun Membranes Composed of PCL and Tilapia-Skin Collagen with Tetracycline or Chloramphenicol in Contact with Human Skin Fibroblasts for Wound Dressing Treatment.

Diabetic foot ulcers are a common complication of diabetes mellitus and can lead to severe infections and delayed wound healing. The development of effective wound dressings is crucial to promoting faster healing and preventing infections. This investigation aims to fabricate and characterize electrospun meshes composed of poly(ε-caprolactone) and collagen, extracted from tilapia skin.
