Special Issue Information

Dear Colleagues,

Electrospinning is a very simple, accurate and versatile technique that allows the production of fibers with controllable diameters ranging from micrometers to nanometers. Over the years, electrospinning became popular for the development of micro/nano fibers with different morphologies, patterns and functionalities, using a variety of materials (e.g. polymers, ceramics and metals). In fact, this technique started to receive increasing attention not only within scientific community but also in industries due to its great potential of application in several advanced areas. Currently and due to the recent pandemic, electrospun nanofibers membranes can play an important role regarding the strong need and demand of personal protection systems with increase filtration efficiency against the airborne virus. Although this application, electrospun nanofibers emerges as strong solutions for other several advanced applications such as: drug delivery, wound dressing, cancer therapy, cosmetics, water and air filtration, protective clothing, sensing, photovoltaic cells, fuel cells, power generation, among others.

Besides the production of nanofibers using biodegradable and natural polymers, the last trend includes the production of advanced electrospun fibers using natural compounds extracted from marine and industrial wastes (textile industry, paper manufacturing) like chitosan, alginates, nanocellulose, etc.

Hence, the aim of this Special Issue is to publish original research and review articles that address these topics and include advances, trends, challenges, and future perspectives regarding synthetic routes, structural features, properties, behaviors, and industrial or scientific applications of electrospun nanofibers in established and emerging areas.

Over the past several decades, the formulation of novel nanofiber-based drug-delivery systems has been a frequent focus of scientists around the world. Aiming to introduce a novel nanofibrous transdermal drug-delivery system to treat pain, the nanofiber mats of buprenorphine-loaded poly (vinyl pyrrolidone) (Bup/PVP) and buprenorphine-loaded poly(vinyl alcohol)/poly(vinyl pyrrolidone) (Bup/PVP/PVA) were successfully fabricated by the electrospinning process for transdermal drug delivery. Similarly, PVP and PVP/PVA nanofibers were fabricated in the same conditions for comparison. The viscosity and electrical conductivity of all electrospinning solutions were measured, and nanofiber mats were characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), Fourier transform infrared (FT-IR) spectroscopy and contact angle analysis. The conductivity of PVP and PVP/PVA solutions showed a considerable increase by the addition of buprenorphine due to the polarity of buprenorphine. SEM images showed a smooth, fine and porous nanofibrous structure without any adhesion or knot for all of the samples. The contact angle analysis showed the increased hydrophilicity and wettability of PVP/PVA and Bup/PVP/PVA nanofibers compared to PVP and Bup/PVP nanofibers which can be attributed to the addition of PVA. Attenuated total reflectance (ATR) FT-IR results confirmed that the electrospinning process did not affect the chemical integrity of the drug. For the modification of the drug release rate, the cross-linking of nanofiber mats was carried out using glutaraldehyde. Drug release measurements using high-performance liquid chromatography (HPLC) analysis demonstrated that Bup/PVP/PVA nanofibers exhibited better physical and chemical properties compared to Bup/PVP. Furthermore, the cross-linking of nanofibers led to an increase in drug release time. Thus, the novel buprenorphine-loaded nanofibers can be efficient biomaterial patches for transdermal delivery against pain improving carrier retention and providing a controlled release of the drug.
