“…It is speculated that the electrospun fibers may form a protective barrier that effectively shields the probiotics from external environmental influences [ 41 ]. This barrier could help maintain their activity by slowing down the heat transfer to the probiotics, possibly also due to the stable microstructure of the electrospun fibers, which encapsulates and secures the probiotics internally, preventing direct damage from high temperatures [ 42 ]. This structure likely helps in maintaining probiotic activity, and the lower moisture content might also play an important role.…”

Probiotics have become increasingly recognized for their potential health-promoting properties; however, the viability of probiotics can be affected by storage and transportation processes as well as the stressful environment of the human digestive tract, preventing them from achieving effective concentration (107 CFU/mL). In this regard, the embedding technology of probiotics provides an effective protection method. Dextran-based water in water (W/W) emulsion loaded with Lactobacillus plantarum was used as spinning solution to prepare Lactobacillus plantarum-loaded electrospun fibers. The structure of the W/W emulsion and the electrospun fibers was charactered. Lactobacillus plantarum were uniformly embedded in the internal phase of the W/W emulsion and the loading efficiency was 9.70 ± 0.40 log CFU/g. After 240 min digestion in the gastrointestinal tract, and temperature treatment in 65 °C and 72 °C, the loaded probiotics maintained high activity. Even after 5 days of storage in room temperature and 4 °C, the loaded probiotic activity levels remained high, with counts >8 log CFU/g. These results suggest that probiotics encapsulated by emulsion electrospinning could be potentially delivered in a novel food delivery system used in the future food industry.

“…In particular, it has been proposed its encapsulation in a polymeric fibrous structure obtained via the electrospinning technique, that is a consolidated and industrially-relevant procedure. [24][25][26][27] Electrospun nanofibers have indeed numerous advantageous characteristics, including a high surface-to-volume ratio, porous structures, and tunable properties (chemical composition, morphology, and dimensions). [28,29] Moreover, it was reported that the integration of nanomaterials as electrodes can improve the sensitivity and reproducibility of electrochemical methods [30] and the detection of HMs.…”

The contamination by heavy metals (HMs) is a pressing issue, due to their serious impact on the environment and human health. Therefore, the design and the development of a sensing material for their detection has gained a lot of attention. In this study, active layers are produced by the electrospinning technique, using three different polymers and disodium salt of ethylenediaminetetraacetic acid (Na2‐EDTA), known to be a chelating substance for heavy metals. The optimized active layer, in terms of polymer type, degree of encapsulation of the salt, as well as salt suitable content, is obtained and tested using the electrochemical impedance spectroscopy technique. The results of the sensing tests indicate the suitability of the developed electrospun layer for environmental monitoring. It is shown the detection of lead in the range of 10–100 000 µg L−1, with a detection limit of 0.031 µg L−1. Moreover, the system is proved to be robust against interfering contaminants such as thallium, another relevant heavy metal.
