“…In recent years, special attention has been paid to the electrospinning process as a simple method of making nanofibre-based structures. Due to the high porosity and area/volume ratios of nanofibres, different active substances with specific properties and with applications in food packaging [1], medicine [2], pharmaceutical drugs [3], fibres based electronics [4] or water treatment [5] can be included.…”

This research aimed to obtain biocompatible and antimicrobial nanofibres based on concentrated collagen hydrolysate loaded with thyme or oregano essential oils as a natural alternative to synthesis products. The essential oils were successfully incorporated using electrospinning process into collagen resulting nanofibres with diameter from 471 nm to 580 nm and porous structure. The presence of essential oils in collagen nanofibre mats was confirmed by Attenuated Total Reflectance -Fourier Transform Infrared Spectroscopy (ATR-FTIR), Ultraviolet–visible spectroscopy (UV–VIS) and antimicrobial activity. Scanning Electron Microscopy with Energy Dispersive Spectroscopy analyses allowed evaluating the morphology and constituent elements of the nanofibre networks. Microbiological tests performed against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Candida albicans showed that the presence of essential oils supplemented the new collagen nanofibres with antimicrobial properties. The biocompatibility of collagen and collagen with essential oils was assessed by in vitro cultivation with NCTC clone 929 of fibroblastic cells and cell viability measurement. The results showed that the collagen and thyme or oregano oil composites have no cytotoxicity up to concentrations of 1000 μg·mL−1 and 500 μg mL−1, respectively. Optimization of electrospinning parameters has led to the obtaining of new collagen electrospun nanofibre mats loaded with essential oils with potential use for wound dressings, tissue engineering or protective clothing.

“…Meanwhile, the tertiary structure can be evaluated by the sodium dodecyl sulfate polyacrylamide gel electrophoresis [44], X-ray diffraction or nuclear magnetic resonance [59]. Comprehensive guidance through the analytical techniques used to investigate the biopolymer fibrous materials' properties can be found in an excellent review by Ricaurte Leidy and Quintanilla-Carvajal Maria Ximena [57]. Some approaches and guidance to properly evaluate the fibrous materials are also listed in the summary by Xue et al [18].…”

Biopolymers formed into a fibrous morphology through electrospinning are of increasing interest in the field of biomedicine due to their intrinsic biocompatibility and biodegradability and their ability to be biomimetic to various fibrous structures present in animal tissues. However, their mechanical properties are often unsatisfactory and their processing may be troublesome. Thus, extensive research interest is focused on improving these qualities. This review article presents the selection of the recent advances in techniques aimed to improve the electrospinnability of various biopolymers (polysaccharides, polynucleotides, peptides, and phospholipids). The electrospinning of single materials, and the variety of co-polymers, with and without additives, is covered. Additionally, various crosslinking strategies are presented. Examples of cytocompatibility, biocompatibility, and antimicrobial properties are analyzed. Special attention is given to whey protein isolate as an example of a novel, promising, green material with good potential in the field of biomedicine. This review ends with a brief summary and outlook for the biomedical applicability of electrospinnable biopolymers.

Engineering the secondary surface morphology of fibers (fibers without smooth surface and solid interior) has been attracting significant awareness in various areas and applications. Among different methods of forming nanofibers, electrospinning is the most widely adopted technique due to the ease of forming fibers with a broad range of properties and its unique advantages such as the flexibility to spin into a variety of shapes and sizes as well as adjustable porosity of electrospun structures. In this review paper, more emphasis is put on the secondary surface morphology. A comprehensive overview of the basic principles about the electrospinning process, types of electrospinning, materials, formation mechanisms, characterizations, and applications of electrospun fibers with the secondary surface morphology (e. g. the porous structure, grooved structure, wrinkled structure, rough structure, cactus structure, and hollow structure) are discussed in detail. Importantly, we believe our work can serve as guidelines for the preparations, characterizations, and applications of electrospun fibers with the secondary surface morphology.
