“…Sajadi et al [84] utilized polyphenolic substances, such as flavonolignans, from Silybum marianum L. seed extracts to reduce copper ions to CuNPs and their own structure was transformed from keto to enol, as shown in Figure 3. Yu et al [135] used nanocellulose to synthesize AgNPs, where positively charged silver ions were attracted to negatively charged carboxyl and hydroxyl groups on nanocellulose. At 80°C, the silver ions were reduced by the hydroxyl groups, which themselves were oxidized to aldehyde groups.…”

Metal nanoparticles (MNPs) have been widely used in several fields including catalysis, bioengineering, photoelectricity, antibacterial, anticancer, and medical imaging due to their unique physical and chemical properties. In the traditional synthesis method of MNPs, toxic chemicals are generally used as reducing agents and stabilizing agents, which is fussy to operate and extremely environment unfriendly. Based on this, the development of an environment-friendly synthesis method of MNPs has recently attracted great attention. The use of plant extracts as reductants and stabilizers to synthesize MNPs has the advantages of low cost, environmental friendliness, sustainability, and ease of operation. Besides, the as-synthesized MNPs are nontoxic, more stable, and more uniform in size than the counterparts prepared by the traditional method. Thus, green preparation methods have become a research hotspot in the field of MNPs synthesis. In this review, recent advances in green synthesis of MNPs using plant extracts as reductants and stabilizers have been systematically summarized. In addition, the insights into the potential applications and future development for MNPs prepared by using plant extracts have been provided.

“…Electrospinning and chemically synthesized CNFs can serve as nanoscale templates for the preparation of various CNF-based 1D nanomaterials. The surface of CNFs could be functionalized first with suitable chemicals and then achieved in combination with nanoparticles [ 25 , 26 , 27 , 28 , 29 , 30 ], quantum dots [ 31 , 32 ], metal-organic frameworks (MOF) [ 32 , 33 ], carbon nanotubes (CNTs) [ 34 ], and others.…”

Cellulose is one of the important biomass materials in nature and has shown wide applications in various fields from materials science, biomedicine, tissue engineering, wearable devices, energy, and environmental science, as well as many others. Due to their one-dimensional nanostructure, high specific surface area, excellent biodegradability, low cost, and high sustainability, cellulose nanofibrils/nanofibers (CNFs) have been widely used for environmental science applications in the last years. In this review, we summarize the advance in the design, synthesis, and water purification applications of CNF-based functional nanomaterials. To achieve this aim, we firstly introduce the synthesis and functionalization of CNFs, which are further extended for the formation of CNF hybrid materials by combining with other functional nanoscale building blocks, such as polymers, biomolecules, nanoparticles, carbon nanotubes, and two-dimensional (2D) materials. Then, the fabrication methods of CNF-based 2D membranes/films, three-dimensional (3D) hydrogels, and 3D aerogels are presented. Regarding the environmental science applications, CNF-based nanomaterials for the removal of metal ions, anions, organic dyes, oils, and bio-contents are demonstrated and discussed in detail. Finally, the challenges and outlooks in this promising research field are discussed. It is expected that this topical review will guide and inspire the design and fabrication of CNF-based novel nanomaterials with high sustainability for practical applications.

“…Moreover, it is convenient to operate, cost-effectiveness, and rapid detection. [28] Presently, various nanomaterials including Cu metalloenzyme, [33] Co 3 O 4 , [34] Au, [30] and Carbon Quantum Dots [23] have been reported for Cys and GSH detection through colorimetric method, however, the material preparation is complicated and required rigorous conditions, for example, high temperature and high pressure. Therefore, to prepare novel functional materials at a moderate condition without using toxic solvents and investigate its applications in Cys and GSH detection needed further exploration.…”

The dynamic and reversible feature of non-covalent interactions endows hydrogel specific response to external stimuli such as temperature, light, pH and oxidant, along with the macroscopic gel-sol transition. [3,[18][19][20] The properties of hydrogels can provide theoretical guidance for their application. However, hydrogels is composed of a large amounts of water and network structure. Since the presence of plenty of water, the hydrogels always have poor mechanical properties, including mechanical strength and viscoelasticity, which greatly influence the application range and the deep insight on the structure-property relationship of hydrogels. Thus, it is very urgent to design LMWGs with functional groups to develop hydrogels with prominent mechanical strength and stability for functional applications. [21][22][23][24] Among the 20 amino acids used as building blocks for proteins, the thiolcontaining amino acids, acting as antioxidants and antidotes, participate in biological activities and metabolic processes, which can retain the cellular defense against xenobiotics, gene regulation, and free radicals signal transduction. [25,26] As the only thiol-containing amino acids, cysteine (Cys) contributes biologically in human body by providing a mode for intermolecular cross-linking of proteins using the disulfide bonding to support the secondary structures and functions. [27] The quantification of Cys is important for accurate prediagnosis of its related disease such as cancer, cardiovascular and cerebrovascular disease. [28] Glutathione (GSH), a thiol-containing tripeptide (l-glutamic acid, l-cysteine, and glycine), is extensively distributed in mammalian and eukaryotic cells. [29] In the tissues, the tripeptide has two forms: reduced (GSH) and oxidized form (GSSH), which maintain the intracellular reduction-oxidation potential. [30] The intracellular level of GSH is a biomarker for various medical conditions and a disease-related physiological regulator. [31] Therefore, it is significant to detect and monitor the Cys and GSH concentration in biological samples as well as cells. Many approaches have been developed for detecting Cys and GSH, such as chromatography, spectroscopy, electrochemistry, and mass spectrometry. However, most of them required sophisticated instrumentation and tedious pretreatment, which Supramolecular hydrogels, based on non-covalent interaction, have outstanding properties, but it is still a big challenge to design hydrogels with higher mechanical properties. In this study, hydrogels with adjustable mechanical properties are prepared by mixing 4′-(4-n-butylimidazole)-pbenzyl-2,2′:6′2″-terpyridine (C 4 -Ter) and zinc ions (Zn 2+ ) in water. The hydrogels are composed of fibrous structure and hierarchical porous structure, which depends on Zn 2+ concentration. Rheological results demonstrate that the hydrogels exhibit prominent mechanical strength with the elastic modulus (G″) and yield stress (τ*) of 200 000 and 1000 Pa, respectively. X-ray diffraction and Fourier-transform infrared spectro...
