“…In the study of Ramadan et al (2020), the eco‐friendly packaging materials treated with silver nitrate in the presence of chitosan and date seed extract gave the best result for resistance to microbes and this led to increased air permeability and water absorbance. In the same way, silver nanoparticles, decorated on polyacrylic acid/graphene matrix, enhanced the thermal stability, chemical resistance, oxygen barrier, and antimicrobial properties (Sethy et al., 2020).…”

The purpose of this study was to prepare an active, nontoxic, and biodegradable film using gelatin and chitosan including rosemary ethanol extract (EE) and essential oil (EO) to improve its physicochemical and antibacterial properties. Films with the highest mechanical properties were acquired using a polymer composition of 4 g gelatin, 3.75 g glycerol, and 1 g chitosan. This composition provided the highest elongation at break (50.10%) and tensile strength (20.61 MPa). The chemical composition of enriched films with rosemary EO was rich in 1,8‐cineole, camphor, camphene, and α‐pinene. The enriched films with rosemary EE were mainly characterized by the predominance of rosmarinic acid and carnosic acid. Mechanical results showed that the incorporation of rosemary EE and EO caused a significant increase in tensile strength, whereas a significant decrease was observed in elongation at break. With the increase of EE and EO concentrations, the water vapor permeability of films decreased while water resistance increased. Moreover, water contact angle analysis showed that the incorporation of rosemary EE and EO made this enriched film more hydrophobic. Fourier transform–infrared (FT‐IR) spectroscopy confirmed the formation of intermolecular hydrogen bonds between component functional groups, enhancing the thermal stability and mechanical properties of the enriched films with rosemary EE and EO. Optical results showed that the incorporation of rosemary EE and EO provoked variations in color, light transmission, and transparency of films. The changes of the surface of these films were confirmed by film microstructure analyses with scanning electron microscope (SEM). The antibacterial activity of enriched films with EO and EE was determined against Escherichia coli, Pseudomonas aeruginosa, Campylobacter jejuni, and Salmonella enterica. In fact, the enriched films with EO and EE showed potential coatings for controlling the most common food‐borne bacterial growth during the food storage. Practical applications Novel techniques of prolonging the shelf life of food products have been evaluated by using the active packaging based on gelatin and chitosan film enriched with natural antibacterial agents from the plant such as phenolics compounds and essential oils. However, there are several problems connected with the strength of such materials. Therefore, the aim of this study was to improve the mechanical properties of control gelatin–chitosan film and to evaluate the influence of the incorporation of rosemary essential oil and extract into the gelatin–chitosan film in order to obtain an active material having antibacterial capacities.

“…The degradation of 3 wt% NBCPs is due to the more amount of PCL associated with the molecule. Reports also suggested that degradation of amino acid based BCPs started before 100 C while PCL seems to degrade around 400 C. 5,29 The grafting of PCL can cause a slight shifting in the material. 30 But these NBCPs show better thermal stability and can be useful for different applications.…”

“…This polymer composite seems to possess very good oxygen barrier behavior by 11 folds with the incorporation of 27 Â 10 À3 wt% of Ag NPs in polyacrylic acid/ GO matrix, which made itself a very good material for packaging applications. 5 Among many biocompatible active polymers, PCL seems to possess a very promising attitude toward the development of many biological devices and tissue engineering accessories. 6 There are two methods to design hydrophobic, semicrystalline like PCL either via ringopening polymerization (ROP) of ε-caprolactone or freeradical ROP of 2-methylene-1,3-dioxepane.…”

Polyacrylic acid (PAA) is a non-toxic, biocompatible, and biodegradable polymer that gained lots of interest in recent years. PAA nano-derivatives can be obtained by chemical modification of carboxyl groups with superior chemical properties in comparison to unmodified PAA. For example, nano-particles produced from PAA derivatives can be used to deliver drugs due to their stability and biocompatibility. PAA and its nanoconjugates could also be regarded as stimuli-responsive platforms that make them ideal for drug delivery and antimicrobial applications. These properties make PAA a good candidate for conventional and novel drug carrier systems. Here, we started with synthesis approaches, structure characteristics, and other architectures of PAA nanoplatforms. Then, different conjugations of PAA/nanostructures and their potential in various fields of nanomedicine such as antimicrobial, anticancer, imaging, biosensor, and tissue engineering were discussed. Finally, biocompatibility and challenges of PAA nanoplatforms were highlighted. This review will provide fundamental knowledge and current information connected to the PAA nanoplatforms and their applications in biological fields for a broad audience of researchers, engineers, and newcomers. In this light, PAA nanoplatforms could have great potential for the research and development of new nano vaccines and nano drugs in the future.
