The transition from insulator to electro-responsive has been successfully achieved by earlier studies for some inorganic materials by applying external stimuli that modify their 3D and/or electronic structures. In the case of insulating polymers, this transition is frequently accomplished by mixing them with other electroactive materials, even though a few physical treatments that induce suitable chemical modifications have also been reported. In this work, a smart approach based on the application of an electro-thermal reorientation process followed by a charged gas activation treatment has been developed for transforming insulating 3D printed polymers into electro-responsive materials.

Introduction: Osteoporosis is a metabolic disorder characterized by the loss of bone mass and density. Nucleic acid-based therapies are among the most innovative approaches for osteoporosis management, although their effective delivery to bone tissue remains a challenge. In this work, SFRP1-silencing GampeR loaded-nanoparticles were prepared and functionalized with specific moieties to improve bone targeting and, consequently, therapeutic efficacy.

Article Synopsis
  • Researchers developed a new type of hydrogel made from hyaluronic acid and a conductive polymer to help heal challenging skin wounds.
  • The addition of the conductive polymer not only increased the porosity and mechanical strength of the hydrogel but also significantly boosted its electrochemical activity.
  • Tests showed that the hydrogel is biocompatible and can enhance cell migration, effectively closing wounds in about 1 hour when stimulated with a small electric voltage.

The sustainable synthesis of urea from ammonia (NH) and carbon dioxide (CO) using ultraporous permanently polarized hydroxyapatite (upp-HAp) as catalyst has been explored as an advantageous CO-revalorization strategy. As the simultaneous activation of N and CO (single-step) demands an increase of the reaction conditions, we have re-visited the industrial two-step Bazarov reaction. upp-HAp has been designed as a stable multifunctional catalyst capable of promoting both CO and NH adsorption for their subsequent C-N bond formation.

Article Synopsis
  • - Osteoporosis is a chronic condition that reduces bone density and quality, leading to increased fragility and risk of fractures, impacting patients' quality of life and healthcare costs significantly.
  • - Early detection and management of osteoporosis are essential to mitigate its effects on individuals and healthcare systems.
  • - In southern Toulouse, the Communauté Professionnelle Territoriale de Santé (CPTS) has created a care pathway with a cooperation protocol to enhance screening for osteoporosis.
