Conjugating AIE-featured AuAg nanoclusters with highly luminescent carbon dots for improved visible-light-driven antibacterial activity

Abstract

Metal nanoclusters (NCs) have emerged as a novel antibacterial agent featuring broad-spectrum antibacterial activity without drug resistance for bacteria, but suffer from fast antibacterial invalidation due to the consumption by...

Revealing the synergetic interaction between amino and carbonyl functional groups and their effect on the electronic and optical properties of carbon dots

“…[16][17][18][19][20] For example, as is well known, the absorption peaks of CDs are mainly in the UV and visible light regions. [21][22][23] Then, our groups utilized a large amount of nitrogen source to broaden the CDs' absorption from UV-Vis to the first NIR window region (650-900 nm), which opened a new potential application as a photothermal agent in photothermal therapy. 24,25 Experimentally, the first NIR absorption window was probably attributed to the nitrogen functional groups.…”

Aggregation-Induced Emission-Active Nanostructures: Beyond Biomedical Applications

“…Likewise, Yuan and Zhu et al reported improved antibacterial activity in a photosensitizer obtained from the conjugation of AIE-active orange-emissive AuAg NCs derived from HAuCl 4 , AgNO 3 , and glutathione, with blue-emitting carbon dots made of branched polyethylenimine and citric acid. 172 Introduction of the latter helped enhance visible lightharvesting ability, charge and energy transfer process, and photostability. This helps create a synergy between the two components which facilitate the large production of ROS under visible light irradiation.…”

A bimetallic Ag15Cu12(S-c-C6H11)18(CH3COO)3 nanocluster featuring an irregular Ag12 kernel

“…Metal nanoclusters (NCs) with atomic precision constitute a special class of nanomaterials due to their well-defined crystal structures, unique physicochemical properties and attractive structure-property correlations and are promising candidates for catalysis, optics, biotechnology and so on. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] Among them, alloy metal NCs containing at least two different metals often lead to the enhancement of the desired properties due to their synergistic effect, 9,18,19 showing that alloying is an effective method to regulate the structure and properties of monometallic nanoclusters.…”
