Nanodrugs
An arginyl‐glycyl‐aspartic acid peptide‐modified carboline ruthenium complex KS‐Ru self‐assembled in a pH‐sensitive manner. It entered the lysosomes and formed nanoflowers, leading to lysosomal swelling. In addition, it entered the nucleus to damage DNA, inducing immunogenic cell death. Thus, it realized a dual impact on tumor growth and metastasis through synergistic chemotherapy and immunogenic...
Several DNA‐damaging antitumor agents, including ruthenium complexes, induce immunogenic cell death (ICD). In this study, an arginyl‐glycyl‐aspartic acid (RGD) peptide‐modified carboline ruthenium complex (KS‐Ru) is synthesized as a chemotherapeutic nanodrug and an ICD inducer. The RGD peptide, an integrin ligand, provides tumor‐specific targeting and promotes self‐assembly of the KS‐Ru complex. The...
Ensuring an appropriate nitrite level in food is essential to keep the body healthy. However, it still remains a huge challenge to offer a portable and low‐cost on‐site food nitrite analysis without any expensive equipment. Herein, a portable integrated electrochemical sensing system (IESS) is developed to achieve rapid on‐site nitrite detection in food, which is composed of a low‐cost disposable...
Point‐of‐care testing (POCT) is experiencing a groundbreaking transformation with microfluidic chips, which offer precise fluid control and manipulation at the microscale. Nevertheless, chip design or operation for existing platforms is rather cumbersome, with some even heavily depending on external drivers or devices, impeding their broader utilization. This study develops a unique programmable gravity...
The hydrogen evolution reaction (HER) activity of defect‐stabilized low‐Pt‐loading catalysts is closely related with defect type in support materials, while the knowledge about the effect of higher‐dimensional defects on the property and activity of trapped Pt atomic species is scarce. Herein, small size (5–10 nm) TiO2 nanoparticles with abundant surface step defects (one kind of line defect) are...
Perovskites
In article number 2307960, Xiao Wang, Longbin Qiu, and co‐workers developed an ultrahigh humidity treatment strategy to facilitate the effective diffusion of formamidinium iodide from the top surface to the buried bottom interface on the sequential vapor‐deposited bilayer structure. High‐efficiency and stable perovskite solar cells deposited by a sequential vapor deposition process with...
The quality of two‐step processed perovskites is significantly influenced by the distribution of organic amine salts. Especially, modulating the distribution of organic amine salts remains a grand challenge for sequential vapor‐deposited perovskites due to the blocking effect of bottom compact PbI2. Herein, an ultrahigh humidity treatment strategy is developed to facilitate the diffusion of formamidinium...
The promising cyclometalated iridium (III) complexes have been proved to possess great potential in vacuum−deposited organic light−emitting diodes (OLEDs) applications for full−color displays and white solid−state lighting sources. Herein, based on the unique bidentate ligand of dibenzo[a,c]phenazine (dbpz) group with strong conjugated effect of aromatic rings for red emission, four novel [3+2+1]...
