“…The output performance of BC lm can be further enhanced by surface modi cation [21], oxygen plasma treatment, and chemical vapor deposition [22], and various chemical functionalization [23] (i.e., nitro [24], aminoalkyl [25], phosphorylation and sulfonation [26]). In addition, fabricating composite materials by adding different kinds of dielectric ller such as BaTiO 3 (BT) [27], Ag NWs/BT [28], ZnO [19], reduced graphene oxide (RGO) [29], and Al 2 O 3 [30] can effectively tailor the electrical outputs toward a higher V OC and I SC .…”

Rapid development of modern wearable-implantable medical devices has led to research on mechanical energy harvesting technologies, especially triboelectric nanogenerator (TENG) for being sustainable/flexible power supply or self-powered sensor. The most challenge part is searching advanced materials and designing them with excellent electrical performance while being flexible, lightweight, and non-toxic. Layered double hydroxides (LDH) have sparked research interest owing to the facile tunability of composition, morphology, and physicochemical properties. In this work, magnesium aluminum layer double hydroxide (MgAl-LDH) nanosheets were employed as a dielectric filler dispersed onto bacterial cellulose (BC) matrix, prior to the application as a friction layer in TENG. Phase identification, functional groups, and morphology of the nitrate-intercalated MgAl-LDH layered crystals have been investigated, including the nanosheets (NS) colloid exfoliated therefrom in formamide. Mechanistic insight with a detailed discussion of experimental results linked to scientific theory is deeply explained. The optimized BC/MgAl-LDH NS (1.5%v/v) film, simply prepared by casting, delivers the open-circuit voltage (VOC), short-circuit current (ISC), and maximum output power (Pmax) of 88.5 V, 87.7 µA and 1250 µW (138 µW/cm2), respectively. The composite serves not only as a nanogenerator driving 200 LEDs but also as a self-powering sensor detecting finger movements that might be useful for developing trigger finger monitoring in future.

This review paper provides an in-depth analysis of recent advancements in integrating two-dimensional (2D) materials with cellulose to enhance biosensing technology. The incorporation of 2D materials such as graphene and transition metal dichalcogenides, along with nanocellulose, improves the sensitivity, stability, and flexibility of biosensors. Practical applications of these advanced biosensors are explored in fields like medical diagnostics and environmental monitoring. This innovative approach is driving research opportunities and expanding the possibilities for diverse applications in this rapidly evolving field.

“…Bacterial cellulose (BC), one type of interpenetrating polymer composed of 100% cellulose, is widely studied in terms of culturing and in applications such as biomedical [ 1 , 2 , 3 , 4 , 5 , 6 ], composites [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ], environmental remediation [ 16 , 17 , 18 , 19 , 20 , 21 ], tissue engineering [ 22 , 23 , 24 ], pharmaceutical [ 25 , 26 , 27 , 28 ], packaging [ 29 , 30 , 31 ], textiles [ 32 , 33 , 34 ], and catalysts [ 35 ]. Due to a networked nanofibrous structure, BC can be fabricated into various forms including hydrogels, aerogels, and films.…”

“…In contrast to Nata de coco , the SCOBY BC is either discarded as waste or collected to be employed as a pellicle starter for the next kombucha tea fermentation. It was found that SCOBY BC exhibited high crystallinity, excellent film formation, and a matrix for bio-composites [ 9 , 10 ]. SCOBY BC can be molded into various sizes and forms depending on the culture container.…”

SCOBY bacterial cellulose (BC) is a biological macromolecule (considered as a by-product) that grows at the liquid–air interface during kombucha tea fermentation. In this study, BC:HC (hydrolyzed collagen) blend films coated with 1 wt% chitosan (CS) were loaded with ascorbic acid to study loading/releasing performance. At first, the mechanical properties of the blend films were found to be dependent on HC ratio. After chitosan coating, the coated films were stronger due to intermolecular hydrogen bonding interaction and the miscibility of two matrixes at the interface. The antibacterial activity test according to the AATCC Test Method revealed that chitosan-coated BC/HC films exhibited excellent antimicrobial activity against S.aureus growth from the underneath and the above film when compared to BC and BC:HC films. Moreover, chitosan was attractive to ascorbic acid during drug loading. Consequently, its releasing performance was very poor. For BC:HC blend films, ascorbic acid loading/releasing performance was balanced by water swellability, which was controlled using blending formulation and coating. Another advantage of BC films and BC:HC blend films was that they were able to maintain active ascorbic acid for a long period of time, probably due to the presence of plenty of BC hemiacetal reducing ends (protective group).
