Hydrophobic mesoporous polymer nanofibre networks were converted to hydrophilic ones by a mild sulfonation reaction. The resultant mesoporous polystyrene with a large free surface area effectively captured water-soluble dye molecules and allowed aromatic compounds to rapidly permeate into the internal binding sites.

Nanofibrous dressing materials with an antitumor function can potentially inhibit recurrence of melanoma following the surgical excision of skin tumors. In this study, hydrolyzed polyacrylonitrile (hPAN) nanofibers biofunctionalized with L-carnosine (CAR) and loaded with bio (CAR)-synthesized zinc oxide (ZnO) nanoparticles, ZnO/CAR-hPAN (hereafter called ZCPAN), were employed to develop an antimelanoma wound dressing. Inspired by the formulation of the commercial wound healing Zn-CAR complex, i.

Chitosan/polyvinyl alcohol nanofibrous mats loaded with nano-hydroxyapatite and/or curcumin are successfully fabricated by the electrospinning method for the first time. Nano-hydroxyapatite is prepared by the co-precipitation method. The XRD pattern of calcined powder at 700 °C for 2 h reveals the presence of hydroxyapatite as a sole phase.

Cardiovascular disease is one of the leading causes of death and serious illness in Europe and worldwide. Conventional treatment-replacing the damaged blood vessel with an autologous graft-is not always affordable for the patient, so alternative approaches are being sought. One such approach is patient-specific tissue bioprinting, which allows for precise distribution of cells, material, and biochemical signals.

Purpose: The purpose of this study is to develop an innovative solution for chronic wounds in high-mobility areas, such as joints, where conventional treatments are hindered by passive healing mechanisms and the need for immobilization. By designing a micro-electro-Nanofiber dressing composed of piezoelectric polyvinylidene fluoride (PVDF) integrated with antimicrobial silver nanoparticles (AgNPs), this research aims to address the dual challenges of promoting effective wound healing and maintaining joint mobility.
Methods: Herein, we developed a novel micro-electro-Nanofiber dressing using electrospinning technology, incorporating polyvinylidene fluoride (PVDF) with silver nanoparticles (AgNPs).

Acellular cellulose-based biomaterials hold promising potential for treating bladder injuries. However, the compromised cellular state surrounding the wound impedes the complete reconstruction of the bladder. This necessitates the development of a bio-instructive cellulose-based biomaterial that actively controls cell behavior to facilitate effective bladder regeneration.
