Understanding the gold core‐ligand interaction in gold nanoclusters (GNCs) is essential for the on‐demand tailoring of their photoluminescence properties and long‐term stability. Here, inspired by the suckers arranged directionally on the tentacles of octopus, a series of GNCs with regulating ligand structures are grown and stabilized on the cellulose nanocrystals (CNCs). The carboxylated CNCs providing...
Gold Nanoclusters
Inspired by the unique structure of octopus suckers arranged directionally on its tentacles, a series of gold nanoclusters (GNCs) grown in situ along cellulose nanocrystals are synthesized. The fluorescence properties and oxidative properties of GNCs are investigated, and a generalized strategy for constructing DCGRFP is provided. More In article number 2307770, Hongxiang Zhu, Hui...
The sensing performance of DNAzymes in live cells is tremendously hampered by the inefficient and inhomogeneous delivery of DNAzyme probes and their incontrollable off‐site activation, originating from their susceptibility to nuclease digestion. This requires the development of a more compact and robust DNAzyme‐delivering system with site‐specific DNAzyme activation property. Herein, a highly compact...
Chemical communication via neurotransmitters is central to brain functions. Nevertheless, in vivo real‐time monitoring of neurotransmitters released in the brain, especially the electrochemically inactive molecules, remains a great challenge. In this work, a novel needle field‐effect transistor (FET) microsensor based on an acupuncture needle is proposed, which is demonstrated to be capable of real‐time...
DNA amplification machines show great promise for intracellular imaging, yet are always constrained by off‐site machinery activation or signal leakage, originating from the inherent thermodynamically driven hybridization between machinery substrates. Herein, an entropy‐driven catalytic DNA amplification machine is integrated with the on‐site amplified substrate exposure procedure to realize the high‐contrast...
Nanozyme has emerged as a versatile nanocatalyst yet is constrained with limited catalytic efficiency and specificity for various biomedical applications. Herein, by elaborately integrating the recognition/transduction carbon dots (CDs) with platinum nanoparticles (PtNPs), an exquisite CDs@PtNPs (CPP) nanoflare is engineered as an efficient and substrate‐specific peroxidase‐mimicking nanozyme for...
Nanobactericides represent one of the most efficient and promising strategies for eliminating bacterial infection considering the increasing resistance threats of conventional antibiotics. Black phosphorus (BP) is the most exciting postgraphene layered 2D nanomaterial with convincing physiochemical properties, yet the study of BP‐based antibiotics is still in its infancy. Here, a compact silver nanoparticle...
