The safe and efficient management of hazardous radioactive iodine is significant for nuclear waste reprocessing and environmental industries. A novel supramolecular framework compound based on cucurbit[8]uril (Q[8]) and 4‐aminopyridine (4‐AP) is reported in this paper. In the single crystal structure of Q[8]‐(4‐AP), two 4‐AP molecules interact with the outer surface of Q[8] and the two other 4‐AP...
The phenotypic heterogeneity of circulating tumor cells (CTCs) and the nonspecific adsorption of background cells impede the effective and sensitive detection of rare CTCs. Although leukocyte membrane coating approach has a good antileukocyte adhesion ability and holds great promise for addressing the challenge of capture purity, its limited specificity and sensitivity prevent its use in the detection...

In article number 2107832, Leonidas Bleris, Zhenpeng Qin, and co‐workers develop a plasmonic sensing method for loop‐mediated isothermal amplification (plasmonic LAMP). It turns complex amplicons into short single‐strand DNA for sequence‐specific detection with plasmonic nanoprobes, achieving improved detection sensitivity and specificity.
The ability to detect pathogens specifically and sensitively is critical to combat infectious diseases outbreaks and pandemics. Colorimetric assays involving loop‐mediated isothermal amplification (LAMP) provide simple readouts yet suffer from the intrinsic non‐template amplification. Herein, a highly specific and sensitive assay relying on plasmonic sensing of LAMP amplicons via DNA hybridization,...
The carrier non‐radiative recombination and instability of device caused by the inherent defects are main factors limiting development of perovskite solar cells (PSCs). During the fabrication process of a PSC device, perovskite films often produce Pb0 and I0 defects. This paper reports a strategy for synergistic optimization of perovskite films by defects passivation and surface modification. The...
Halide perovskites are promising photoactive materials for filter‐free color‐imaging sensors owing to their outstanding optoelectronic properties, tunable bandgaps, and suitability for large‐scale fabrication. However, producing patterned perovskite films of sufficiently high quality for such applications poses a challenge for existing fabrication methods: using solution processes to prepare patterned...
In article number 1903254, Jia Guo, Yu Chen, Huixiong Xu, and co‐workers fabricate ultrasmall dual‐targeting iridium nanocrystals modified with tumor cell‐targeting RGD peptides and nucleus‐targeting TAT proteins for effective tumor localization and nucleus targeting, inducing prominent sensitized tumor radiotherapy.
Prominent tumor‐cell nucleus targeting of radiosensitizer substantially affects the therapeutic consequence of advanced tumor radiotherapy via lethal nucleus DNA damage. Herein, ultrasmall iridium nanocrystals (Ir NCs, <5 nm) are constructed for efficient tumor‐specific photonic hyperthermia‐synergized radiotherapy. To endow the NCs with qualified cell nucleus‐targeting performance, polyethylene...
