Chemodynamic therapy (CDT) is a highly targeted approach to treat cancer since it converts hydrogen peroxide into harmful hydroxyl radicals (OH·) through Fenton or Fenton‐like reactions. However, the systemic toxicity of metal‐based CDT agents has limited their clinical applications. Herein, a metal‐free CDT agent: 2,4,6‐tri(4‐pyridyl)‐1,3,5‐triazine (TPT)/ [closo‐B12H12]2−(TPT@ B12H12) is reported...
Insight into fundamental light‐matter interaction as well as underlying photo‐physical processes is crucial for the development of novel optoelectronic devices. Palladium diselenide (PdSe2), an important representative of emerging 2D noble metal dichalcogenides, has gain considerable attention owing to its unique optical, physical, and chemical properties. In this study, 2D PdSe2 nanosheets (NSs)...
Photodetectors
The cover image describes the design of three‐electrode photo‐electrochemical photodetectors based on lanthanide‐doped carbon quantum dots (CQDs). Owing to the coordination of lanthanides and internal energy transfer between lanthanides and CQDs, the as‐fabricated photodetectors not only show an excellent photo‐response performance, but also exhibit a narrow‐band response behavior....
The present work demonstrates a facile hydrothermal approach to synthesize lanthanide‐doped carbon quantum dots (CQDs) with europium and/or gadolinium elements. Taking the advantage of broadband adsorption in the ultraviolet‐visible region, the doped QDs are directly used as building blocks for photo‐electrochemical (PEC)‐type photodetectors (PDs) and their performance is systematically investigated...
2D PbS nanoplatelets (NPLs) form an emerging class of photoactive materials and have been proposed as robust materials for high‐performance optoelectronic devices. However, the main drawback of PbS NPLs is the large lateral size, which inhibits their further investigations and practical applications. In this work, ultra‐small 2D PbS NPLs with uniform lateral size (11.2 ± 1.7 nm) and thickness (3.7 ±...
Organic luminogens constitute promising prototypes for various optoelectronic applications. Since gaining distinct color emissions normally requires the alternation of the conjugated backbone, big issues remain in material synthetic cost and skeleton compatibility while pursuing full‐color luminescence. Upon a facile one‐step coupling, three simple but smart perchalcogenated (O, S, and Se) arenes...
The adsorption and dynamics of cystine, which is the oxidized dimer of cysteine where the monomers are connected through a disulfide bond, on the Au(110) surface, in water solution, is characterized by means of classical molecular dynamics simulations based on a recently developed reactive force field (ReaxFF). The adopted computational procedure and the force field description are able to give a...
On page 6134, S. Monti and co‐workers present classical reactive (ReaxFF) molecular dynamics simulations of the adsorption of cysteine on gold supports. The cover image represents a gold vehicle functionalized with cysteine molecules moving in the blood stream towards its target cells. All the steps of the mechanism, namely physisorption, disulfide bond breaking, chemisorption, formation of staples,...
