“…CNFs with widths of 10 to 30 nm and lengths of several microns show potential applications in the area of transparent films, strong materials, foods, cosmetics, flexible displays, pharmaceutical application, and electrochemistry due to their excellent properties of large surface area, light weight, high Young's modulus, low coefficient of thermal expansion, biodegradability, and biocompatibility (Nishino et al 2004;Nishiyama 2009;Nogi and Yano 2009;Nyholm et al 2011;Li et al 2012;Lin and Dufresne 2014). However, efficient production of CNF is still facing the challenges of high energy consumption and a need to increase capacity.…”

Cellulose nanofibrils (CNFs) are bionanomaterials with many promising properties and great potential in composite applications. Herein, welldispersed and uniform-sized cellulose nanofibrils were successfully obtained from commercially bleached softwood kraft pulp, resulting in yields of 79.15% via enzyme-assisted hydrolysis and subsequent homogenization. Field emission scanning electron microscopy (FE-SEM) confirmed the fiber morphology. The water retention value (WRV) was increased from 107% of original pulp to 1384% of the resulting CNFs, while crystallinity had no significant changes. Fourier transform infrared (FTIR) spectroscopy indicated that enzymes degraded a portion of hemicelluloses and residual lignin. CNFs subjected to enzymatic treatment and homogenization had a less entangled network, larger aspect ratio, and higher transmittance than those from pure mechanical treatment. They were well dispersed in an aqueous solution and uniformly sized in morphology, resolving the present challenge of nanomaterials tendency for agglomeration. These results revealed that the enzymeassisted process had a remarkable effect on the production of CNFs and made CNFs more appealing for nanotechnology applications and nanomaterial.

“…Meanwhile, Li et al reported a green synthesis of AgNP-GO nanocomposite using glucose as a reducing and stabilizing reagent. 39 Compared with the previous AgNP-GRO, 37,38 Ag + was similarly reduced but GO was not reduced, which followed the manner of the previous fabrication of AgNP films on GO. 40 The thus prepared AgNP-GO nanocomposite was dissolved in DMF, cast on the surface of the GCE, and dried with an infrared lamp.…”

While increasing attention has been devoted to the use of carbon-based nanomaterials or metal nanoparticles (MNPs) as electrode modifiers for electroanalysis, there is a noticeable development in studies using MNP-graphene nanocomposites or nanohybrids in very recent years. In this review, first, very recent nanoarchitectures in MNP-graphene nanocomposites for modifying electrodes (mainly in 2013) are summarized together with the targets and achievements of electroanalysis. The variety of nanoarchitectures comes from the fact that graphene oxide and metal precursor ions can be reduced chemically or electrochemically, and concurrently or stepwisely. By browsing various preparation methods of the modified electrodes, some characteristic and interesting features of the preparations of MNP-graphene nanocomposites are described together with the possibilities and prospects as electrode modifiers for electroanalysis.

“…Chemical reduction is one of the most applied methods for the preparation of AgNPs colloidal dispersions in water or organic solvents [37][38][39]. In recent years biological synthesis of Ag nanoparticles has received attention over the physical and chemical synthesis as a clean, non-toxic and eco-friendly approach [40][41][42].…”
