Most sensors are based on ceramic or semiconducting substrates, which have no flexibility or biocompatibility. Polymer-based sensors have been the subject of much attention due to their ability to collect molecules on their sensing surface with flexibility. Beyond polymer-based sensors, the recent discovery of cellulose as a smart material paved the way to the use of cellulose paper as a potential candidate for mechanical as well as electronic applications such as actuators and sensors. Several different paper-based sensors have been investigated and suggested. In this paper, we review the potential of cellulose materials for paper-based application devices, and suggest their feasibility for chemical and biosensor applications.

Per- and polyfluoroalkyl substances (PFAS) are a widely used class of synthetic chemicals that pose a significant global environmental and health threat due to their persistent and bioaccumulation toxicity caused by strong C-F bonds in their structures. PFAS usually exist in trace concentrations in environmental water bodies, which poses great challenges for environmental analysis. In this study, environmentally friendly cellulose was modified with polyaniline through in situ oxidative polymerization, and used as the filter paper for solid-phase extracting 23 PFAS in water.

The anthocyanin-loaded films based on natural polymers as pH-responsive indicator are widely applied in the food preservation. However, the low mechanical strength and storage stability limited their practical application, there is an urgent demand to improve the performance of anthocyanin-loaded films. In order to avoid affecting the color indication of anthocyanins, we explored the effect of eight kinds of white nanomaterials on improving the performance of films.

Superhydrophilic hydrogel was typically used as the membrane coating on various substrates for oil/water separation. Nevertheless, these coatings may suffer from such limitations as poor adhesion strength and abrasion-resistance. Thus, the facile construction of hydrogel sponge with 3D connecting channels would be an ideal choice.

Cellulose nanocrystals (CNCs) are powerful biosourced nanomaterials for the construction of chiral photonic films. While various techniques have been used to enrich the optical properties of such systems, surface roughness engineering has yet to be exploited to significantly modify their optical properties. In this work, by using vacuum filtration-assisted self-assembly, CNCs are densely packed into films with high optical transparency.

The contamination of water resources by selenium (Se), particularly in the highly toxic Se(IV) oxidation state, poses a significant environmental and public health concern due to its detrimental impacts on humans and aquatic ecosystems. In this work, we report a novel composite foam (CFC) by incorporating chitosan (CS), cellulose nanofibers (CNF) and iron oxyhydroxide (FeOOH) nanoparticles through a one-pot fabrication process. The CFC foam features a three-dimensional porous structure, conferring both exceptional mechanical strength and superior adsorption performance for Se(IV), with a maximum equilibrium adsorption capacity of 90 mg/g achieved within 3 h.
