“…As a low-dimensional material, zero-dimension (0D) is the first to appear and be used, such as 0D gold nanoparticle. [103] In general, 0D materials contain nanoparticle, [104] nanocrystalline, [105,106] and quantum dots, [107] etc, which have attracted much attention and research in the field of energy storage considering their advantages, such as small size, large specific surface area, and more exposed active points. However, its small size and abundant active sites on surface also make it prone to agglomeration.…”

In various energy storage devices, the development and research of electrode materials has always been a key factor. Nb‐based materials are one choice of energy storage materials because of the good ion‐diffusion channels and high theoretical capacity. More importantly, their advantages, such as safe potential range, high structural stability, and highly reversible redox reaction with small strain, are conducive to efficient, safe, and stable energy storage development. Based on aforementioned superiority, much of the research is to further optimize performance of Nb‐based materials by unique nano‐morphology design, lattice regulation, and functional additives composition, showing good electrochemical performance in many kinds of devices. This review mainly introduces the classification of Nb‐based materials used for energy storage, their application in different battery systems, and common optimization methods. Accordingly, the deficiencies and prospects of Nb‐based materials are also discussed in detail.

“…Anisotropic nonspherical micro-/nanomaterials have attracted extensive interests due to their superior physicochemical and biological properties in diverse fields over their spherical counterparts. [1][2][3][4][5][6][7][8] Among these anisotropic structures, anisotropic silver nanoplatelet/ nanosheet has gained considerable attentions in recent years as a result of its fascinating plasmonic properties, biological activity, and long-term stability. [9] To date, a variety of solution-based conventional batch strategies have been developed to synthesize silver nanoplatelet/nanosheet, such as electrochemical synthesis, sonochemical route, biological synthesis, thermal synthesis, templating method, and chemical reduction.…”

Microfluidic reactors represent a new frontier in the rational design and controllable synthesis of functional micro-/nanomaterials. Herein, we develop a continuous and ultrafast flow synthesis method to obtain triangular silver (tAg) nanoplatelet using a short range two-loop spiral-shaped laminar flow microfluidic reactor, with one inlet flow containing AgNO 3 , trisodium citrate, and H 2 O 2 and the other NaBH 4. The effect of the reactant concentration and flow rate on the structural changes of tAg is examined. Through the same miniaturized microreactor, hierarchical core-shell Ag@SiO 2 can be produced with tunable silica shell thickness using one inlet flow containing the as-synthesized Ag nanoparticles together with tetraethyl orthosilicate and the other ammonia. The enhanced cellular internalization efficiency of triangular nanoplatelets by PANC-1 and MCF-7 cells is further confirmed in comparison with the spherical ones. These results not only bring new insights for engineering nanomaterials from microreactors but also facilitate the rational design of functional nanostructures for enhancing their biological performance.

“…The fluorescence intensity of dyes can be quenched by gold NPs as a result of fluorescence resonance energy transfer and collision processes between these two [ 94 ]. The degree of quenching is dependent on the size and shape of the nanoparticles [ 95 ]; for instance, well dispersed nanosize gold NPs significantly quench the intensity, while aggregated particles are not efficiently quenched [ 94 ]. Based on aggregation phenomena, various optical and electrochemical aptasensors were developed for molecules that trigger the aggregation by using different strategies.…”

Recent years have witnessed an overwhelming integration of nanomaterials in the fabrication of biosensors. Nanomaterials have been incorporated with the objective to achieve better analytical figures of merit in terms of limit of detection, linear range, assays stability, low production cost, etc. Nanomaterials can act as immobilization support, signal amplifier, mediator and artificial enzyme label in the construction of aptasensors. We aim in this work to review the recent progress in mycotoxin analysis. This review emphasizes on the function of the different nanomaterials in aptasensors architecture. We subsequently relate their features to the analytical performance of the given aptasensor towards mycotoxins monitoring. In the same context, a critically analysis and level of success for each nano-aptasensing design will be discussed. Finally, current challenges in nano-aptasensing design for mycotoxin analysis will be highlighted.
