Transition metal oxides (TMOs) and their heterostructure hybrids have emerged as promising candidates for hydrogen evolution reaction (HER) electrocatalysts based on the recent technological breakthroughs and significant advances. Herein, Ru‐Co oxides/Co3O4 double‐shelled hollow polyhedrons (RCO/Co3O4‐350 DSHPs) with Ru‐Co oxides as an outer shell and Co3O4 as an inner shell by pyrolysis of core‐shelled...
This work reports exquisite engineering of catalytic activity of DNA‐templated silver nanoclusters (DNA‐AgNCs) based on unique adsorption phenomena of DNAs on DNA‐AgNCs and reversible transition between double and triple‐stranded DNAs. Four DNA homopolymers exhibit different inhibition effects on the catalytic activity of DNA‐AgNCs, poly adenine (polyA) > poly guanine (polyG) > poly cytosine...
Nanomaterial‐based pancreatic cancer treatment has received widespread attention and rapid development in the past few years. The major challenges include the poor combination of diagnosis and therapy, the difficulty in targeting therapy from the root and the unsatisfactory antitumor efficiency, which is accompanied by a great risk of relapse and metastasis. In this work, a positively charged lipid...
Photothermal conversion ability (PCA) and cell internalization ability (CIA) are two key factors for determining the performance of photothermal agents. The previous studies mostly focus on improving the PCA by exploring new photothermal nanomaterials. Herein, the authors take the hybrids of graphene and gold nanostar (GGN) as an example to investigate the gradually enhanced phototherapy effect by...
