“…The findings obtained presented that all CNFs and CNCs had a considerable ability to increase the antiOVA IgG response. Roohani et al [ 98 ] synthesized new green nanocomposites based on poly(vinyl alcohol) (PVA) with CNCs and functional Fe 3 O 4 (FMNP) as a potential adjuvant. Despite the fact that PVA has been utilized widely in the biomedical area, including the administration of drugs and vaccines, its usage has certain limitations, including poor heat stability, high flammability, and only moderately strong mechanical qualities.…”

A key element in ensuring successful immunization is the efficient delivery of vaccines. However, poor immunogenicity and adverse inflammatory immunogenic reactions make the establishment of an efficient vaccine delivery method a challenging task. The delivery of vaccines has been performed via a variety of delivery methods, including natural-polymer-based carriers that are relatively biocompatible and have low toxicity. The incorporation of adjuvants or antigens into biomaterial-based immunizations has demonstrated better immune response than formulations that just contain the antigen. This system may enable antigen-mediated immunogenicity and shelter and transport the cargo vaccine or antigen to the appropriate target organ. In this regard, this work reviews the recent applications of natural polymer composites from different sources, such as animals, plants, and microbes, in vaccine delivery systems.

“…[33,34] In particular, the hydroxyl groups from PVA interact with the hydroxyl groups from natural fibers to generate strong hydrogen bonds, allowing for the fabrication of "green" nanocomposite for industrial applications. [35] In addition, based on natural, degradable, flexible polymer substrates, currently multifunctional sensors with high strain sensitivity and rapid electrothermal response have not received as widely studied. Hence, there is an urgent need to develop multifunctional wearable sensors with high sensitivity and rapid response for strain variation.…”

Here, a flexible film, called PPA film, is designed as a multifunctional sensor with high electrical conductivity, rapid electrothermal response, and high strain sensitivity. The film contains polyvinyl alcohol (PVA), graphene nanosheets (GNs), nanocellulose crystals (CNCs), polydopamine (PDA), and silver nanoparticles (Ag NPs), symbolized as PPA film. The CNCs enhance the dispersion of the GNs during film formation; the stacked GNs change heat conduction and resistance during film bending; PDA serves as a linking agent; Ag NPs improve the conductivity (i.e., 2.65 × 103 S/m) of the film during electrothermal response measurement. A flexible strain sensor designed from PPA films is mounted on the skin surface of human joints to monitor human movement in real time. The sensor exhibited good stability and cycling durability, i.e., the resistance variation remained stable during the bend‐release repetitions for 600 cycles at 1.2 % strain. The flexible sensors exhibited highly sensitive to bending strain, i.e., 30.5 of the gauge factor (GF), and can be applied to monitor bending motions of human joints, such as finger, wrist, elbow, and knee joints.In addition, the PPA films exhibit very high joule heat generation ability and demonstrate its applicability as a joint or stomach warmer and sensor. The as‐designed flexible sensor is a promising candidate for application in environmentally friendly and multifunctional wearable devices.

“…The resulting hydrogen bonds enhance the interaction forces and play a positive role in improving the comprehensive properties of silicone rubber composites. 24 Comparing with the liquid metal without a silica “protective shell”, it was found that the core–shell microstructure improved the thermal stability and dielectric properties of PDMS. In addition, the surface modification of nanoparticles was studied to improve the incompatibility of the inorganic nanoparticles with the organic matrix and improve the comprehensive performance of PDMS.…”
