Bioinspired structural color sensors based on self-assembled cellulose nanocrystal/citric acid to distinguish organic solvents

Recent advances in cellulose nanocrystals-based sensors: a review

“…160 Verma et al reported layer-by-layer EISA-assisted CNCs-based humidity sensors. 7 These are some recent reports where different methods have been used to fabricate CNCs-based sensors for humidity, chemical, gas, sweat, and metal ion sensing. The detailed construction and classification of such sensors are described in the upcoming sections on metal, gas, chemical, physical stimuli, and biomaterial sensing.…”

“…8,36,[57][58][59][60][61][62][63][64][65] Recently, there has been growing interest in nano-cellulosic materials due to their versatile applications and unique properties. 7,36,[66][67][68] Consequently, cellulose is a promising material for developing sensors that exhibit enhanced sensing sensitivity. 69 The cellulose structure is characterized by a polymer with a linear chain consisting of 1,4-glycosidic linkages between D-glucopyranose subunits.…”

“…Such sensors are prepared by printing, coating, or laminating functional materials like graphene, carbon nanotubes (CNTs), nanocellulose, polypyrrole (PPy), and metal nanowires. [3][4][5][6][7][8][9] Graphene oxide (GO) was dipcoated on yarn and reduced to make a wearable strain sensor. The prepared sensor can identify slight speech vibrations and forceful human motions like jogging, walking, and jumping.…”

Synergistic effect of hybrid hydroxylated boron nitride and cellulose nanocrystals for enhancing the thermal, mechanical, and hydrophobic properties of composite film

“…Verma et al prepared CNC/citric acid-based structural color sensors to distinguish organic solvents. [56] Wan et al prepared a BN-based hybrid film for optoelectronic applications. [57] The incorporation of BN and CNC hybrid filler into biodegradable composites expands its applicability in fields also including mechatronics, [58] implants, [59] hydrogel, [24] thermal management, [60] biomedical, [61] and thermal conductive applications.…”
