“…The peak centered at 1053 cm -1 indicates C-OH stretching of the secondary alcohol whereas the one at 1031 cm -1 corresponds to C-OH stretching of the primary alcohol in the cellulose backbone. And, the peak positioned at 662 cm -1 is for C-OH out of plane bending of cellulose units [48,50,51].…”

Hybrid paper sheets were prepared by applying a thin coating layer of cross-linked polydimethylsiloxane (PDMS) and inorganic particles onto Whatman Grade 1 filter paper substrates. Several coatings with different inorganic particle contents and types were applied onto the paper substrates to investigate the effect of the variation in the coating formulation on the (i) wetting, (ii) water barrier properties, (iii) air barrier properties, (iv) surface roughness, and (v) mechanical properties of the samples. It was revealed that the superhydrophobic hybrid paper sheets with significantly low air permeability and high water barrier properties could be prepared which is an indication that the method proposed can be used for the preparation of packaging materials.

“…The main fabrication protocols involve pencil drawing, printing, vacuum filtration, soak and polymerization, and dipcoating. 7,15,18,20 As for the conductive materials for paper-based electrodes, carbon-based materials and conducting polymers are mostly used because of their outstanding electrochemical activity and easy diffusion into the porous paper. However, the top priority of an ideal electrode should be high electrical conductivity.…”

Technology advances in flexible and wearable electronics have promoted the booming development for high-performance flexible electrodes. In this work, we fabricated a highly conducive paper-based electrode by coating silver nanoparticles (AgNPs) on common cellulose paper using a polymer-assisted metal deposition strategy, where the mussel-inspired polydopamine (PDA) layer was applied as an interface to facilitate the bonding between paper substrates and AgNPs. Dense AgNPs can directly grow on the surface of PDA-coated paper at mild conditions, forming a highly conductive layer. The as-fabricated flexible paper electrode displays a high electrical conductivity of 4058.1 S/m and low sheet resistance of 6.5 Ω/sq, which outperforms many reported counterparts. Moreover, with the strong interfacial reinforcement by PDA, the AgNPs adhere to the paper tightly and the electrode presents a notable stability under sonication and mechanical bending. The used paper is low cost and environmentally friendly, and the preparation process is simple and green without the need of extreme conditions or strong solvents, which can be scaled up to large-scale fabrication.

“…Paper-based nanocomposite is the latest functional material of unique merits, in brief, low cost, porosity, and disposability are the inherent advantages that this raw material provides [2,3]. Beyond these, more potentials have appeared in diverse applications such as antibacterial sheet [4], energy-harvesting platform [5] and highly efficient catalyst [6]. Meanwhile, the first investigation on cellulose-metal nanocomposite was reported in 1984 [7] for surface-enhanced Raman scattering (SERS) sensing research as we are best known.…”

Tear glucose is an intriguing biofluid that includes potential biomarkers. While many sensors have emerged nowadays, there is still demand for advanced sensors with nonenzymatic, simple, cost-effective sensing mechanism. Herein, we present a paper-based colorimetric assay by utilizing a gold nanoparticle formation. Experimental characterization substantiated a mechanism in this in situ reduction. Scanning electron microscopy, UV-visible spectrometry, etc. were involved in the scrutiny. As a result, we reached for the rationale whereas the particle formation can be utilized for a glucose sensing using tears. This paper-based detection was insusceptible to physiological tear matrix, i.e., chloride ion effect, false-positive error and synergistic effect by antioxidants. In addition, we evaluated its analytical performance in an artificial tear assay. Of the obtained a linear regressions, the concentration range corresponded to the physiological or pathologic reference range. In addition, within the low-concentration range, a high correlation was resulted 0.965. Furthermore, we investigated statistical validation by employing the Bland–Altman plot. In the end sections of this paper, we denoted its ready-to-use merits by simplicity—as well as the further application of our plasmonic paper.
