“…Successful drug delivery needs supports from both pharmaceutical excipients, pharmaceutical techniques, and their effective combinations [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]. To a certain extent, the fields of pharmaceutics and drug delivery rely heavily on the inputs of materials sciences (new excipients) and engineering (new techniques) [ 8 , 9 , 10 , 11 , 12 , 13 ]. Thus, during the past half a century, on the one hand, more and more types of materials (including natural polymers, synthesis polymers, phospholipid, surfactants, and even inorganic materials) have been tried as new drug carriers for adjusting the drug release performances [ 14 , 15 , 16 , 17 , 18 ].…”

One of the most important trends in developments in electrospinning is to combine itself with traditional materials production and transformation methods to take advantage of the unique properties of nanofibers. In this research, the single-fluid blending electrospinning process was combined with the casting film method to fabricate a medicated double-layer hybrid to provide a dual-phase drug controlled release profile, with ibuprofen (IBU) as a common model of a poorly water-soluble drug and ethyl cellulose (EC) and polyvinylpyrrolidone (PVP) K60 as the polymeric excipients. Electrospun medicated IBU-PVP nanofibers (F7), casting IBU-EC films (F8) and the double-layer hybrid films (DHFs, F9) with one layer of electrospun nanofibers containing IBU and PVP and the other layer of casting films containing IBU, EC and PVP, were prepared successfully. The SEM assessments demonstrated that F7 were in linear morphologies without beads or spindles, F8 were solid films, and F9 were composed of one porous fibrous layer and one solid layer. XRD and FTIR results verified that both EC and PVP were compatible with IBU. In vitro dissolution tests indicated that F7 were able to provide a pulsatile IBU release, F8 offered a typical drug sustained release, whereas F9 were able to exhibit a dual-phase controlled release with 40.3 ± 5.1% in the first phase for a pulsatile manner and the residues were released in an extended manner in the second phase. The DHFs from a combination of electrospinning and the casting method pave a new way for developing novel functional materials.

“…The endothelial cells grow rapidly and induce the formation of blood vessels in the granulation tissue, the damaged tissue is gradually replaced by epithelial cells and fibroblasts, and the wound surface is gradually filled with granulation tissue. Maturation is the final stage in which connective tissue is formed and the new epithelium is strengthened [ 26 , 27 ]. Figure 1 shows the physiological process of wound healing.…”

Wounds have become one of the causes of death worldwide. The metabolic disorder of the wound microenvironment can lead to a series of serious symptoms, especially chronic wounds that bring great pain to patients, and there is currently no effective and widely used wound dressing. Therefore, it is important to develop new multifunctional wound dressings. Hydrogel is an ideal dressing candidate because of its 3D structure, good permeability, excellent biocompatibility, and ability to provide a moist environment for wound repair, which overcomes the shortcomings of traditional dressings. This article first briefly introduces the skin wound healing process, then the preparation methods of hydrogel dressings and the characteristics of hydrogel wound dressings made of natural biomaterials and synthetic materials are introduced. Finally, the development prospects and challenges of hydrogel wound dressings are discussed.

“…Electrochemical sensor detection mainly uses the following electrochemical analysis methods. Cyclic voltammetry (CV) is a widely used electroanalysis method that provides information about electrochemical reaction rate in the analyte solution ( Li Jiankang et al, 2021 ). The principle is that the electric current at a constant scan rate is recorded as the electrode potential varies over time between the two potential limits.…”

Diabetes is a chronic, systemic metabolic disease that leads to multiple complications, even death. Meanwhile, the number of people with diabetes worldwide is increasing year by year. Sensors play an important role in the development of biomedical devices. The development of efficient, stable, and inexpensive glucose sensors for the continuous monitoring of blood glucose levels has received widespread attention because they can provide reliable data for diabetes prevention and diagnosis. Electrospun nanofibers are new kinds of functional nanocomposites that show incredible capabilities for high-level biosensing. This article reviews glucose sensors based on electrospun nanofibers. The principles of the glucose sensor, the types of glucose measurement, and the glucose detection methods are briefly discussed. The principle of electrospinning and its applications and advantages in glucose sensors are then introduced. This article provides a comprehensive summary of the applications and advantages of polymers and nanomaterials in electrospun nanofiber-based glucose sensors. The relevant applications and comparisons of enzymatic and non-enzymatic nanofiber-based glucose sensors are discussed in detail. The main advantages and disadvantages of glucose sensors based on electrospun nanofibers are evaluated, and some solutions are proposed. Finally, potential commercial development and improved methods for glucose sensors based on electrospinning nanofibers are discussed.
