This work proposes the concept of single‐cell microRNA (miR) therapy and proof‐of‐concept by engineering a nanopipette for high‐precision miR‐21‐targeted therapy in a single HeLa cell with sensitive photoelectrochemical (PEC) feedback. Targeting the representative oncogenic miR‐21, the as‐functionalized nanopipette permits direct intracellular drug administration with precisely controllable dosages,...
Discrete organometallic complexes with defined structures are proceeding rapidly in combating malignant tumors due to their multipronged treatment modalities. Many innovative superiorities, such as high antitumor activity, extremely low systemic toxicity, active targeting ability, and enhanced cellular uptake, make them more competent for clinical applications than individual precursors. In particular,...
Cyano‐rich g‐C3N4 materials are widely used in various fields of photochemistry due to the very powerful electron‐absorbing ability and electron storage function of cyano, as well as its advantages in improving light absorption, adjusting the energy band structure, increasing the polarization rate and electron density in the structure, active site concentration, and promoting oxygen activation ability...
Human beings have a greater need to pursue life and manage personal or family health in the context of the rapid growth of artificial intelligence, big data, the Internet of Things, and 5G/6G technologies. The application of micro biosensing devices is crucial in connecting technology and personalized medicine. Here, the progress and current status from biocompatible inorganic materials to organic...
Triple ionic and electronic conductivity (TIEC) in cathode materials for protonic ceramic fuel cells (PCFCs) is a desirable feature that enhances the spatial expansion of active reaction sites for electrochemical oxygen reduction reaction. The realization of optimal TIEC in single‐phase materials, however, is challenging. A facile route that facilitates the optimization of TIEC in PCFC cathodes is...
In article number 1805509, Ying‐Wei Yang and co‐workers construct conjugated macrocycle polymer nanoparticles consisting of dual macrocyclic rings, i.e., pillarenes and porphyrins, as alternating strut/node components in the skeleton, followed by the immobilization of Pd nanoparticles via a simple post‐treatment method. The resulting composite nanomaterials exhibit excellent stability, remarkable...
Conjugated macrocycle polymers (CMPs) integrated using the macrocyclic confinement effect make imposing restrictions feasible on the growth of metal nanoparticles with confined size and high dispersion. For a proof‐of‐concept exploration, a novel nanoscale CMP is reported, denoted as DMP[5]‐TPP‐CMP, comprising two representative types of macrocyclic compounds, i.e., pillararene and porphyrin, as alternating...
The precise integration of microscale dots and lines with controllable interfacing connections is highly important for the fabrication of functional devices. To date, the solution‐processible methods are used to fabricate the heterogeneous micropatterns for different materials. However, for increasingly miniaturized and multifunctional devices, it is extremely challenging to engineer the uncertain...
Theranostic nanoprobes integrated with diagnostic imaging and therapy capabilities have shown great potential for highly effective tumor therapy by realizing imaging‐guided drug delivery and tumor treatment. Developing novel high‐performance nanoprobes is an important basis for tumor theranostic application. Here, near‐infrared (NIR) fluorescent and low‐biotoxicity Ag2Se quantum dots (QDs) have been...
