“…Accurate transfer and positioning of thin NFMs onto specific surfaces or substrates become difficult due to their small size and lightweight properties, and they may be more susceptible to tearing or damage when manipulated. To address this challenge, a promising approach involves the in-tegration of nano/microfabrication techniques, [151,152] such as melt spinning and 3D printing, with electrospinning in developing NFM-based cell culture platforms. This approach enables the production of composite materials that combine electrospun NFMs with microfibers, preserving the inherent properties of NFMs while simultaneously facilitating easier manipulation and handling.…”

“…This approach enables the production of composite materials that combine electrospun NFMs with microfibers, preserving the inherent properties of NFMs while simultaneously facilitating easier manipulation and handling. [151,152] Moreover, a prominent concern frequently raised when employing NFMs as cell culture platforms is related to image resolution. NFMs consist of an interconnected network of NFs, leading to the scattering and trapping of light within this network structure, resulting in the overall opacity of the NFM.…”

Nanofiber membranes (NFMs), which have an extracellular matrix (ECM)‐mimicking structure and unique physical properties, have garnered great attention as biomimetic materials for developing physiologically relevant in vitro organ/tissue models. Recent progress in NFM fabrication techniques immensely contributed to the development of NFM‐based cell culture platforms for constructing physiological organ/tissue models. However, despite the significance of the NFM fabrication technique, an in‐depth discussion of the fabrication technique and its future aspect was insufficient. This review provides an overview of the current state‐of‐the‐art of NFM fabrication techniques from electrospinning techniques to post‐processing techniques for the fabrication of various types of NFM‐based cell culture platforms. Moreover, the advantages of the NFM‐based culture platforms in the construction of organ/tissue models are discussed especially for tissue barrier models, spheroids/organoids, and biomimetic organ/tissue constructs. Finally, the review concludes with perspectives on challenges and future directions for fabrication and utilization of NFMs.This article is protected by copyright. All rights reserved

“…One possible solution is redirecting the blood flow from one area to another by reconnecting blood vessels (artery, vein, capillary). This redirection and reconnection of the blood flow can be achieved with vascular grafts (autografts or synthetic) (Martínez-González et al, 2017;Shahriari-Khalaji et al, 2023). Another cardiac pathology is valve problems.…”

Cardiac medical devices (CMDs) are required when the patient’s cardiac capacity or activity is compromised. To guarantee its correct functionality, the building materials in the development of CMDs must focus on several fundamental properties such as strength, stiffness, rigidity, corrosion resistance, etc. The challenge is more significant because CMDs are generally built with at least one metallic and one polymeric part. However, not only the properties of the materials need to be taken into consideration. The biocompatibility of the materials represents one of the major causes of the success of CMDs in the short and long term. Otherwise, the material will lead to several problems of hemocompatibility (e.g., protein adsorption, platelet aggregation, thrombus formation, bacterial infection, and finally, the rejection of the CMDs). To enhance the hemocompatibility of selected materials, surface modification represents a suitable solution. The surface modification involves the attachment of chemical compounds or bioactive compounds to the surface of the material. These coatings interact with the blood and avoid hemocompatibility and infection issues. This work reviews two main topics: 1) the materials employed in developing CMDs and their key characteristics, and 2) the surface modifications reported in the literature, clinical trials, and those that have reached the market. With the aim of providing to the research community, considerations regarding the choice of materials for CMDs, together with the advantages and disadvantages of the surface modifications and the limitations of the studies performed.

“…are some of the widely used forms of dressing materials. Sponges with appropriate gas exchange, acceptable mechanical properties, favorable interconnected pore size, and a noticeable capability of fluid absorption and holding are widely used as a suitable wound dressing. , Additionally, the nanofibrous electrospun membrane is also extensively utilized as a functional structure for wound treatment as it provides a high surface area, mimics the extracellular matrix (ECM), has outstanding mechanical properties, and has exceptional and adaptable chemical, physical, and biological properties. – The main drawback of single-layer wound dressings is that they cannot imitate the hierarchical structure of the skin and provide all clinical needs. , Sponge matrices are preferable to thin membranes for healing full-thickness wounds, but on the other hand, nanofibrous membranes have an ECM-like structure and are more suitable for cell adhesion and proliferation. Therefore, by creating a nanofibrous layer under the sponge matrix, the advantages of both structures can be achieved .…”
