“…In the starch‐graft‐polyacrylonitrile nanofiber system, as the acceleration voltage increased from 5 to 25 kV, the average diameter of the nanofibers decreases from 0.38 to 0.24 µm. As the flow rate increased from 1.0 to 2.5 mL·h −1 , the diameter increased from 0.35 to 0.51 µm (Sun et al., 2018). Wang et al.…”

In recent years, starch‐based nanoparticles have attracted great interest due to their small size, good biocompatibility, and environmental friendliness, as well as their potential applications in foods, drug delivery carriers, and biodegradable edible films. Compared with nonstarch polysaccharides, starch can be enzymatically hydrolyzed into glucose in vivo, so it can be used as an enzyme‐responsive carrier. The recent research progress of starch‐based nanoparticles, including starch nanoparticles, starch nanospheres, starch micelles, starch vesicles, starch nanogels, and starch nanofibers, are reviewed in this paper. The main focus is on their responsiveness, digestibility, toxicity, interactions with other components, and applications. Starch‐based nanoparticles are nontoxic and responsive to pH, temperature, light, and other stimuli. It can interact with proteins, antioxidants, and lipids through electrostatic interactions and hydrogen bonding interactions. Starch‐based nanoparticles have a wide range of applications, including enhancing the mechanical properties of films and gels, stabilizing emulsions, as a fluorescent indicator, a catalyst, and a nanocarrier to control the release of active ingredients and drugs.

“…[15] Researchers have demonstrated the promises of electrospinning as an encapsulation technology for drug delivery, [10][11][12] using a wide range of natural polymers, including proteins [16][17][18][19] and starch. [20][21][22][23] Up until recently, starch-based electrospun fibers were being produced with high amylose content starches [20,21,24] or modified starch as starch-graft-polyacrylonitrile [25] and starchgraft-poly(butyl acrylate/styrene). [26] Our research group has shown that it is possible to electrospun fibers from starch with normal amylose content which is cost effective, biodegradable, biocompatible, and abundant in nature.…”

Electrospun Starch Nanofibers as a Delivery Carrier for Carvacrol as Anti‐Glioma Agent

et al. 2021

Phenolic compounds are prone to degradation from external deleterious conditions. Thus, a carrier for its delivery can be useful in protecting them and ensuring their optimal release profile. The objective of this study is to produce starch nanofibers as delivery carriers for carvacrol and to evaluate its in-vitro digestion simulation and anti-glioma activity. Nanofibers are produced by electrospinning of a starch solution where carvacrol is incorporated in various concentrations (20, 30, and 40% v/w; dry basis). The nanofibers are evaluated by in-vitro digestion simulation and anti-tumoral activity in C6 rat glioma cells and cytotoxicity in astrocytes. By measuring the residual amount of carvacrol after digestion, the starch nanofibers are shown to be a promising vehicle for the delivery of carvacrol by resisting in-vitro digestion. The carvacrol-loaded starch nanofibers result in up to 50% reduction in tumoral cells (C6 rat glioma cells). Free carvacrol elicits cytotoxicity in astrocytes after 72 h of treatment; interestingly the carvacrol-loaded starch nanofibers are not toxic to this cell. In view of the demand for natural drugs in pharmaceutical applications, the nanofibers may be promising for cancer complementary treatment.

“…PAN is a semicrystalline thermoplastic and its monomer, that is, acrylonitrile (AN) is widely used to fabricate co‐polymers with methyl methacrylate , starch , and lignin in order to modify the property of PAN. In earlier literature, different biopolymers like starch , tragacanth gum , alginate , soybean protein , silk fibroin , and casein are grafted to PAN for enhanced water resistance, tensile strength, biocompatibility, and adsorption behaviors. However, the combination of BSA with PAN is new in the literature.…”

Effect of layered graphene oxide on the structure and properties of bovine serum albumin grafted polyacrylonitrile hybrid bionanocomposites

2019

Herein, one‐pot synthetic protocol is utilized to synthesize graphene oxide (GO) reinforced bovine serum albumin grafted polyacrylonitrile (BSA‐g‐PAN) microspheres through emulsifier‐free in situ emulsion polymerization route by using potassium persulfate (KPS) as initiator. The surface morphologies of pure PAN, BSA‐g‐PAN hybrid polymer, and BSA‐g‐PAN/GO hybrid bionanocomposites are observed through scanning electron microscope. Pure PAN shows the self‐assembled cauliflower like morphology which is found to be structurally interfered due to grafting between BSA and PAN. Moreover, the growth of cauliflower like morphology is influenced by the incorporation of GO platelets within BSA‐g‐PAN matrix, due to strong interfacial adhesion between GO and PAN. Transmission electron microscopy, X‐ray diffraction, and atomic force microscopy techniques are used to evaluate structural distributions of layered GOs within BSA‐g‐PAN chains. Due to filling up of microvoids of BSA‐g‐PAN structure by the GO layers, the oxygen permeability of the hybrid bionanocomposite is reduced by 22 folds with incorporation of only 3 wt% of GO. Moreover, the BSA‐g‐PAN/GO hybrid bionanocomposite shows significant antibacterial activities against bacteria such as S. aureus and E. coli. Primarily, thermal, gas barrier, biodegradability, antimicrobial, and mechanical properties of the synthesized hybrid bionanocomposites are studied to explore the hybrid bionanocomposite in packaging applications.
