“…A gelatin film with magnetic nanoparticles can be used as a control system for drug release, where the use of a magnetic field is important. Research has confirmed that without a magnetic field, this type of film acts as a blockage of drug release, while under the influence of a magnetic field, it opens the diffusion pathways [207]. Javanbakht and Namazi (2018) obtained flexible nanocomposite CMC hydrogel films with graphene quantum dots and anticancer drug, doxorubicin, release property.…”

Waste from non-degradable plastics is becoming an increasingly serious problem. Therefore, more and more research focuses on the development of materials with biodegradable properties. Bio-polymers are excellent raw materials for the production of such materials. Bio-based biopolymer films reinforced with nanostructures have become an interesting area of research. Nanocomposite films are a group of materials that mainly consist of bio-based natural (e.g., chitosan, starch) and synthetic (e.g., poly(lactic acid)) polymers and nanofillers (clay, organic, inorganic, or carbon nanostructures), with different properties. The interaction between environmentally friendly biopolymers and nanofillers leads to the improved functionality of nanocomposite materials. Depending on the properties of nanofillers, new or improved properties of nanocomposites can be obtained such as: barrier properties, improved mechanical strength, antimicrobial, and antioxidant properties or thermal stability. This review compiles information about biopolymers used as the matrix for the films with nanofillers as the active agents. Particular emphasis has been placed on the influence of nanofillers on functional properties of biopolymer films and their possible use within the food industry and food packaging systems. The possible applications of those nanocomposite films within other industries (medicine, drug and chemical industry, tissue engineering) is also briefly summarized.

“…Así mismo, se ha estudiado la remoción de múltiples cationes (Cr 3+ , Cr 6+ , Cd 2+ , Cu 2+ , Ni 2+ , Zn 2+ ) aprovechando el magnetismo de la magnetita [34] y aniones (SO 4 2− , Cr 2 0 7 2− , AsO 4 3− ) [35][36][37], entre otros. Existe estudios en una gran variedad de soportes para elaborar compositos con la magnetita, entre los soportes más usuales se destaca la gelatina [38], celulosa [39], siliconas [40] y óxidos de grafeno [41].…”

Environmental pollution by heavy metals has been extensively researched using different materials and techniques but, this problem has not been fully resolved. High adsorption capacity of iron oxides such as hematite, magnetite, goethite and, ferrihydrite to remove arsenic are described in this review. There are many international investigations about the minerals of iron oxides and they describe the composition, properties, synthesis methods and involved variables. Active carbon, silicones and polymers had been used to obtain composites with iron oxides and they have gave better results to remove different anions and cations. The aim in this paper is to introduce studies already carried out and encourage research in this topic to take advantage of the particular characteristics of iron oxides and use them in the environmental remediation. In addition, it is important to introduce the natural iron oxides availability that have a lot of field to study. The literature search on the subject was carried out in Science Direct and high impact articles related to natural or synthetic oxides were used. Keywords: Arsenic, hematite, magnetite, goethite, iron composites. Resumen La contaminación ambiental por metales se ha estudiado mucho con diferentes materiales y técnicas, pero aún no se ha logrado resolver por completo este problema. La alta capacidad de adsorción de los óxidos de hierro como la hematita, magnetita, goetita, ferrihidrita, para la remoción de arsénico en agua son descritos en este trabajo de revisión. Existen muchas investigaciones internacionales de los óxidos de hierro en las que se expone la composición de estos minerales, las propiedades, métodos de síntesis y las variables que intervienen. El carbón activo, las siliconas y los polímeros son materiales que se han usado para formar compositos con estos óxidos que han contribuido a obtener mejores resultados en la remoción de diferentes aniones y cationes. Con este trabajo se pretende difundir estudios ya realizados e incentivar la investigación en este campo para aprovechar las características particulares de los óxidos de hierro y usarlos como remediadores ambientales. Ademas, es importante dar a conocer la existencia de óxidos de hierro naturales que dejan mucho campo por estudiar.

“…This technique is advantageous as it minimizes the effects caused by non-magnetic forces and ensures only the record of magnetic forces [226,227]. The use of MFM in biopolymer systems is marginally explored and is limited to the analysis of magnetic biocomposites [83,[228][229][230][231]. The magnetic properties of the magnetic nanoparticles loaded biopolymeric systems can be evaluated by means of MFM.…”

“…The magnetic properties of the magnetic nanoparticles loaded biopolymeric systems can be evaluated by means of MFM. Since the biopolymers have no response to the external magnetic field (Figure 16) [228], MFM provides information regarding the dispersion and encapsulation of magnetic nanoparticles inside the biopolymer matrix [83]. The aggregations of magnetic nanoparticles can also be determined by measuring the variation in frequency shifts vs. the position of the tip [228].…”

Natural biopolymers, a class of materials extracted from renewable sources, is garnering interest due to growing concerns over environmental safety; biopolymers have the advantage of biocompatibility and biodegradability, an imperative requirement. The synthesis of nanoparticles and nanofibers from biopolymers provides a green platform relative to the conventional methods that use hazardous chemicals. However, it is challenging to characterize these nanoparticles and fibers due to the variation in size, shape, and morphology. In order to evaluate these properties, microscopic techniques such as optical microscopy, atomic force microscopy (AFM), and transmission electron microscopy (TEM) are essential. With the advent of new biopolymer systems, it is necessary to obtain insights into the fundamental structures of these systems to determine their structural, physical, and morphological properties, which play a vital role in defining their performance and applications. Microscopic techniques perform a decisive role in revealing intricate details, which assists in the appraisal of microstructure, surface morphology, chemical composition, and interfacial properties. This review highlights the significance of various microscopic techniques incorporating the literature details that help characterize biopolymers and their derivatives.
