“…Heteroatom-doped CNDs have been developed for theranostics as well, thanks to nanozyme activity [ 308 ]. Many other examples of nanozymes based on CNDs have been reported, through addition of other components, such as hemin [ 309 ], metal nanoparticles (NPs) [ 310 , 311 ], co-doping with various elements [ 312 , 313 , 314 ], MOFs [ 315 ], carbon nitride [ 316 ], and metal oxides [ 317 ].…”

Carbon nanomaterials (CNMs) and enzymes differ significantly in terms of their physico-chemical properties—their handling and characterization require very different specialized skills. Therefore, their combination is not trivial. Numerous studies exist at the interface between these two components—especially in the area of sensing—but also involving biofuel cells, biocatalysis, and even biomedical applications including innovative therapeutic approaches and theranostics. Finally, enzymes that are capable of biodegrading CNMs have been identified, and they may play an important role in controlling the environmental fate of these structures after their use. CNMs’ widespread use has created more and more opportunities for their entry into the environment, and thus it becomes increasingly important to understand how to biodegrade them. In this concise review, we will cover the progress made in the last five years on this exciting topic, focusing on the applications, and concluding with future perspectives on research combining carbon nanomaterials and enzymes.

“…A flexible and highly sensitive humidity sensor, capable of monitoring human breath, was based on TEMPO-oxidized nanofibrillated cellulose and CNTs [104]. An electrochemical biosensor for three adenosine triphosphate (ATP) metabolites, namely uric acid, xanthine and hypoxanthine, was based on a composite of NH 2 -MWCNT/black phosphorene/AgNPs, dispersed in carboxymethyl cellulose [102]. Another electrochemical molecularly-imprinted sensor was based on a nanofibrous membrane prepared by the electrospinning technique from cellulose acetate, MWCNTs and polyvinylpyrrolidone, and was used for determining ascorbic acid [151].…”

“…In addition, nanocellulose/nanocarbon composites are promising for biomedical applications, though these applications are less frequent than industrial applications. Biomedical applications include radical scavenging [34,92], photothermal ablation of pathogenic bacteria [93], photodynamic and combined chemophotothermal therapy against cancer [35,94], drug delivery [16,28,65,72,[95][96][97], biosensorics [31][32][33]63,66,71,91,[98][99][100][101][102][103][104], and particularly tissue engineering and wound dressings. Hybrid materials containing nanocellulose and nanocarbons stimulated the growth and osteogenic differentiation of human bone marrow mesenchymal stem cells [37,59].…”

Applications of Nanocellulose/Nanocarbon Composites: Focus on Biotechnology and Medicine

Nanocellulose/nanocarbon composites are newly emerging smart hybrid materials containing cellulose nanoparticles, such as nanofibrils and nanocrystals, and carbon nanoparticles, such as “classical” carbon allotropes (fullerenes, graphene, nanotubes and nanodiamonds), or other carbon nanostructures (carbon nanofibers, carbon quantum dots, activated carbon and carbon black). The nanocellulose component acts as a dispersing agent and homogeneously distributes the carbon nanoparticles in an aqueous environment. Nanocellulose/nanocarbon composites can be prepared with many advantageous properties, such as high mechanical strength, flexibility, stretchability, tunable thermal and electrical conductivity, tunable optical transparency, photodynamic and photothermal activity, nanoporous character and high adsorption capacity. They are therefore promising for a wide range of industrial applications, such as energy generation, storage and conversion, water purification, food packaging, construction of fire retardants and shape memory devices. They also hold great promise for biomedical applications, such as radical scavenging, photodynamic and photothermal therapy of tumors and microbial infections, drug delivery, biosensorics, isolation of various biomolecules, electrical stimulation of damaged tissues (e.g., cardiac, neural), neural and bone tissue engineering, engineering of blood vessels and advanced wound dressing, e.g., with antimicrobial and antitumor activity. However, the potential cytotoxicity and immunogenicity of the composites and their components must also be taken into account.

“…10,11 However, by grafting functional groups on PEDOT, the interaction between PEDOT derivatives and the detection objects is expected to be improved, so that PEDOT derivatives most likely play a greater advantage in electrochemical detection. 12 According to previous reports, introduction of functional groups into PEDOT may increase its adsorption and detection range. 13−16 However, similar to the unmodified PEDOT, PEDOT modified by functional groups such as −NH 2 and −SH still shows unstable electrochemical performance, structural collapse during the redox process, and easy agglomeration.…”

In this paper, carboxylated cellulose (CLC) dissolved in [BMIM]Cl as a soft template combined with the functional group (−NH2, −SH)-grafted poly(3,4-ethylene dioxythiophene) (PEDOT) derivatives was synthesized by an in situ polymerization method. Structural analysis revealed that CLC increased the degree of conjugation of the polymers in the composites and also led to the formation of the fibrous and sheet structure of the composite. The results of the electrochemical performance measurements revealed that the electrode modified by PEDOT-MeNH2/CLC and PEDOT-MeSH/CLC had detection limits (S/N = 3) of 0.38(0.1–380 μM) and 0.042(0.02–520 μM) for the detection of guanine (G), while for the detection of uric acid (UA), the corresponding detection limits (S/N = 3) were 0.255(5–400 μM) and 0.085(0.4–650 μM). The PEDOT-MeSH/CLC-based electrochemical sensor also possessed a wide linear response with the detection limits of 0.077(0.6–620 μM) and 0.144(0.2–460 μM) for the simultaneous detection of UA and G, respectively.
