Nanocrystalline Cellulose-Assisted Generation of Silver Nanoparticles for Nonenzymatic Glucose Detection and Antibacterial Agent

Abstract

Nanocrystalline cellulose (NCC) is a kind of natural biopolymers with merits of large surface area, high specific strength and unique optical properties. This report shows that NCC can serve as the substrate, allowing glucose to reduce Tollen's reagent to produce silver nanoparticles (AgNPs) at room temperature. The generation of AgNPs is affected by the factors such as the concentrations of silver ions, NCC and glucose, as well as the different reaction temperatures. The AgNPs with NCC are applied for the development of a visual, quantitative, nonenzymatic and high-sensitive assay for glucose detection in serum. This assay is also used for monitoring the concentration change of glucose in medium during cell culture. For the antibacterial activity, the minimal inhibitory concentration (MIC) of the generated AgNPs with NCC is much lower than that of commercial AgNPs, attributed to the good dispersion of AgNPs with the presence of NCC. As NCC exhibits unique advantages including green, stable, inexpensive, and abundant, the NCC-based generation of AgNPs may find promising applications in clinical diagnosis, environmental monitoring, and the control of bacteria.

“…Nanomaterials are currently regarded as a rich source to synthesize desired alternative mimic enzymes with the benefits of low cost, plentiful raw materials, and ease in purification and storage. Many nanomaterials with intrinsic enzyme-mimetic activity analogous to that of natural enzymes were fabricated, such as metal organic frameworks [ 12 ], Pt nanoclusters [ 13 ], silver nanoparticles [ 14 ], and gold nanoparticles [ 15 ]. Although enormous progress has been made, the discovery and development of novel promising artificial peroxidase mimics is still in urgent need.…”

“…Consequently, cellulose has attracted significant interest as a remarkable reinforcement for biocomposites . Nanocrystalline Cellulose (NCC), procured by cellulose acidolysis, has many attractive and excellent properties, such as nanoscale dimensions and large specific surface area as well as admirable mechanical strength and modulus, which have attracted great consideration for use in polymer nanocomposites . In addition, NCC is biodegradable and renewable, which makes it a perfect agent for enhancing biobased materials and biodegradable polyesters, such as poly(butylene succinate) (PBS) , and poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) (PHBV) , and poly(lactic acid) (PLA) .…”
