“…Because of its structural similarities to the extracellular matrix, and its gelling properties under conditions compatible with biological activities, it is widely used in biomedical engineering applications, for example, drug delivery, in vitro cell culture, wound healing, and tissue engineering [ 31 , 32 , 33 ]. Electrospun alginate-based nanofibers have been developed for use in biomedical applications such as wound dressing [ 34 , 35 , 36 ], tissue engineering [ 37 , 38 ], and drug delivery systems [ 39 , 40 ]. The SA polymer in a water-based solution cannot be electrospun alone due to its inadequate chain entanglements.…”

Green electrospun materials are gaining popularity in the quest for a more sustainable environment for human life. Bee pollen (BP) is a valuable apitherapeutic product and has many beneficial features such as antioxidant and antibacterial properties. Alginate is a natural and low-cost polymer. Both natural materials show good compatibility with human tissues for biomedical applications and have no toxic effect on the environment. In this study, bee pollen-loaded sodium alginate and polyvinyl alcohol (SA/PVA) nanofibrous mats were fabricated by the electrospinning technique. The green electrospun nanofibrous mats were analyzed by scanning electron microscopy (SEM), Fourier transforms infrared spectroscopy (FTIR), and differential scanning calorimeter (DSC). According to the findings of the study, the toxin-free electrospinning method is suitable for producing green nanomaterial. Because of the useful properties of the bee pollen and the favorable biocompatibility of the alginate fibers, the bee pollen-loaded SA/PVA electrospun mats have the potential for use in a variety of biomedical applications.

“…Halochromic materials can have a crucial role as sensors for various purposes, in healthcare or tness industries, or even serve as a sensor for acid rain (Van der Schueren and de Clerck 2012a, b; Van Der Schueren et al 2012; Cao et al 2018;Promphet et al 2019;Stojkoski and Kert 2020). The most common challenges of application of pH-sensitive dyes to textile materials are the proper compatibility of dye-ber system and the appropriate range of pH sensitivity for targeted application (Van der Schueren and de Clerck 2011; Sun et al 2015;Pakolpakcil et al 2018). Ideally, pH response of functional materials should be fast, stable, ensuring proper visible warning.…”

Halochromic cellulose textile obtained via dyeing with biocolorant isolated from Streptomyces sp. strain NP4

Halochromic (pH-responsive) material was obtained by dyeing functionalized viscose fabric with a crude extract from Streptomyces sp. strain NP4. The functionalization of the pristine fabric before dyeing was performed to make cellulose susceptible to coloration with NP4 extract. Two combined pre-treatment protocols were used, oxidation to obtain dialdehyde cellulose and chitosan deposition onto pristine and oxidized cellulose. Functionalization by both protocols made viscose susceptible to dyeing with the notion that the latter deposition of chitosan produced a darker shade on the material. Dyed fabrics showed visual pH responsiveness in the range pH 4-10, with a color change from pink to red (pH 4 to pH 7) and a major color change from red to blue (pH 7 to pH 10) whereby fabric was tested and could withstand 10 color-changing cycles. Cytotoxicity assay con rmed the non-toxic nature of dyed material, which indicates its possible use as wound dressing's indicators.

“…For example, Agarwal et al [24] fabricated universal pH sensing nanofibrous sensors using various halochromic dyes with Nylon 6. Pakolpakçıl et al [26] used natural halochromic dye with a sodium alginate and polyvinyl alcohol mixture to fabricate pH-indicating nanofibrous sensors. Getmeyer et al [27] fabricated nanofibrous sensors using a combination of electrospinning and sol-gel methods to detect gaseous NH 3 and HCl.…”

For the immediate detection of strong gaseous alkalis and acids, colorimetric textile sensors based on halochromic dyes are highly valuable for monitoring gas leakages. To date, colorimetric textile sensors for dual-gas detection have usually been fabricated by electrospinning methods. Although nanofibrous sensors have excellent pH sensitivity, they are difficult to use commercially because of their low durability, low productivity, and high production costs. In this study, we introduce novel textile sensors with high pH sensitivity and durability via a facile and low-cost screen-printing method. To fabricate these textiles sensors, Dye 3 and RhYK dyes were both incorporated into a polyester fabric. The fabricated sensors exhibited high detection rates (<10 s) and distinctive color changes under alkaline or acidic conditions, even at low gas concentrations. Furthermore, the fabricated sensors showed an outstanding durability and reversibility after washing and drying and were confirmed to contain limited amounts of hazardous materials. Thus, our results show that the fabricated textile sensors could be used in safety apparel that changes its color in the presence of harmful gases.
