“…However, the activity of immobilized cellulase decreases in a slower speed than that of free cellulase, suggesting a better pH tolerance in enzyme immobilization. These conclusions are similar to previous studies (Liu et al 2013; Mubarak et al 2014; Kim et al 2017). PH of 3.0 offers the best stability for immobilized and free cellulase (Fig.…”

Cellulase has many potential applications in ethanol production, extraction of medicinal ingredients, food, brewing, oil exploration, environmental protection. However, the widespread use of cellulase is limited by its relatively high production costs and low biological activity. Therefore, we studied the enzymatic properties and reusability of cellulase immobilized on multiwalled carbon nanotubes and sodium alginate for the first time. The results showed that the optimum temperature and pH of immobilized cellulase was 40 °C and 3.0, respectively. After 1 month of storage at 4 °C, the enzyme activity of immobilized cellulase dropped to 71.2% of the baseline. Immobilized cellulase was proved to be reusable and maintained ~ 70% of its activity after 7 cycles of repeated use. Versus free cellulase, the immobilized cellulase showed good thermal stability, pH resistance, storage stability and reusability, which could be beneficial in large-scale industrial manufacturing processes.

“…Functionalized graphene forms a highly stable dispersion in various solvents, including water, N,N‐dimethyl formamide (DMF) and dimethyl sulfoxide (DMSO). To date, IL‐functionalized CNTs and graphene have been utilized only in several limited application areas, such as chemical and biomolecule sensing . However, they are potentially useful for diverse new applications.…”

Outstanding pristine properties of carbon nanotubes and graphene have limited the scope for real-life applications without precise controllability of the material structures and properties. This invited article to celebrate the 25th anniversary of Advanced Materials reviews the current research status in the chemical modification/doping of carbon nanotubes and graphene and their relevant applications with optimized structures and properties. A broad aspect of specific correlations between chemical modification/doping schemes of the graphitic carbons with their novel tunable material properties is summarized. An overview of the practical benefits from chemical modification/doping, including the controllability of electronic energy level, charge carrier density, surface energy and surface reactivity for diverse advanced applications is presented, namely flexible electronics/optoelectronics, energy conversion/storage, nanocomposites, and environmental remediation, with a particular emphasis on their optimized interfacial structures and properties. Future research direction is also proposed to surpass existing technological bottlenecks and realize idealized graphitic carbon applications.

“…Table 1 summarizes this sensor performance based on PtAuNPs-CTAB-GR nanocomposites and other relevant sensor materials collected from literatures. We found that the performance of proposed sensor was better than other nonenzymatic H 2 O 2 sensors or comparable to some enzyme-biosensors [12,38].…”

“…Among these, electrochemical technique has attracted considerable interest due to its inherent advantages of simplicity, high sensitivity, fast response and low-cost [8]. Recently, numerous enzymes modified electrodes were frequently used for detecting relatively low concentrations of H 2 O 2 [9][10][11][12]. Nevertheless, the relatively of high cost, limited lifetime and the critical operating situation limit enzyme-biosensor applicability.…”
