Pyroptosis, a new mode of regulatory cell death, holds a promising prospect in tumor therapy. The occurrence of pyroptosis can trigger the release of damage‐associated molecular patterns (DAMPs) and activate the antitumor immune response. Moreover, enhancing intracellular reactive oxygen species (ROS) generation can effectively induce pyroptosis. Herein, an integrated nanoplatform (hCZAG) based on...
Clustered regularly interspaced short palindromic repeat (CRISPR)‐associated protein 9 (Cas9) is a promising gene editing tool to treat diseases at the genetic level. Nonetheless, the challenge of the safe and efficient delivery of CRISPR/Cas9 to host cells constrains its clinical applicability. In the current study, a facile, redox‐responsive CRISPR/Cas9‐Ribonucleoprotein (RNP) delivery system by...
Flexible broadband photodetectors are desired but challenging to be fabricated for next‐generation wearable intelligent optoelectronic devices.

The increasing demand for wearable electronics calls for advanced energy storage solutions that integrate high electrochemical performances and mechanical robustness. Ionogel is a promising candidate due to its stretchability combined with high ionic conductivity. However, simultaneously optimizing both the electrochemical and mechanical performance of ionogels remains a challenge. This paper reports...
Age‐related bone defects are a leading cause of disability and mortality in elderly individuals, and targeted therapy to delay the senescence of bone marrow‐derived mesenchymal stem cells (MSCs) has emerged as a promising strategy to rejuvenate bone regeneration in aged scenarios. More specifically, activating the nicotinamide adenine dinucleotide (NAD+)‐dependent sirtuin 1 (SIRT1) pathway is demonstrated...
The precise design of low‐cost, efficient, and definite electrocatalysts is the key to sustainable renewable energy. The urea oxidation reaction (UOR) offers a promising alternative to the oxygen evolution reaction for energy‐saving hydrogen generation. In this study, by tuning the lattice expansion, a series of M‐FeNi layered double hydroxides (M‐FeNi LDHs, M: Mo, Mn, V) with excellent UOR performance...
Efficient artificial photosynthesis of disulfide bonds holds promises to facilitate reverse decoding of genetic codes and deciphering the secrets of protein multilevel folding, as well as the development of life science and advanced functional materials.

Perovskite solar cells (PSCs) with n‐i‐p structures often utilize an organic 2,2′,7,7′‐tetrakis (N, N‐di‐p‐methoxyphenyl‐amine) 9,9′‐spirobifluorene (spiro‐OMeTAD) along with additives of lithium bis(trifluoromethanesulfonyl)imide salt (LiTFSI) and tert‐butylpyridine as the hole transporting layer (HTL). However, the HTL lacks stability in ambient air, and numerous defects are often present on the...
The development of specific and sensitive immunomagnetic cell separation nanotechnologies is central to enhancing the diagnostic relevance of circulating tumor cells (CTCs) and improving cancer patient outcomes. The limited number of specific biomarkers used to enrich a phenotypically diverse set of CTCs from liquid biopsies has limited CTC yields and purity. The ultra‐high molecular weight mucin,...
Conventional ion‐selective membranes, that is ion‐exchange and porous membranes, are unable to perform high conductivity and selectivity simultaneously due to the contradictions between their ion selecting and conducting mechanisms.

Infection classification is the key for choosing the proper treatment plans. Early determination of the causative agents is critical for disease control. Host responses analysis can detect variform and sensitive host inflammatory responses to ascertain the presence and type of the infection. However, traditional host‐derived inflammatory indicators are insufficient for clinical infection classification...
Solid catalyst is widely recognized as an effective strategy to control the chirality of single‐walled carbon nanotubes (SWNTs).
