This paper demonstrates a novel active-ion-gated strategy to active the room temperature (RT) gas sensing performance of ZnO NWs by self-powered triboelectric plasma system in ambient environment. The activated ZnO NWs shows considerable sensitivity, excellent selectivity, and rapid response to acetone gas at RT with maximum power consumption only 4.5 mW. Abstract: Reducing the high operation …

A SOD-inspired copper single-atom nanozyme (Cu-SAzyme) was designed and synthesized by a two-step scaffold-adsorption method. The Cu-SAzyme exhibits high catalytic activity to scavenge superoxide anion, the initiator of ROS, and thus effectively prevents the disease progression in septic animals. Abstract: Sepsis is a systemic inflammatory response syndrome with high morbidity and mortality mediated by infection-caused …

We herein developed a nucleus-specific RNAi nanoplatform for targeted regulation of nuclear lncRNA function and effective cancer therapy. This new RNAi nanoplatform could respond to the endosomal pH to expose NTPA/siRNA complexes for the nucleus-specific siRNA delivery, leading to a significant inhibition of nuclear lncNEAT2 expression and tumor growth of liver cancer. Abstract: In the …

It is challenging to develop new preparation methods of conductive polymer-based composite hydrogels for constructing all-in-one supercapacitors (A-SCs) with excellent deformation-tolerant performance. Self-wrinkled polyaniline-based composite hydrogels (SPCHs) with large stretchability and excellent fatigue resistance are fabricated by a stretching/cryopolymerization/releasing strategy. The as-obtained SPCH can work as an intrinsically stretchable A-SC maintaining high energy density and …

Low photoconversion efficiency and limited tissue penetration are the major barriers for photothermal therapy (PTT) agent application. Here, an efficient organic/inorganic dual-PTT agent guided by MRI was proposed. It is proved the oxygen vacancy band narrowed its band gap that led to NIR-II region absorb. Furthermore, the defect energy level trapping carrier and conjugate synergistic …

Clinically approved indocyanine green (ICG) is utilized to develop simple prodrug nanoformulations. The ICG-driven assembly strategy endows paclitaxel prodrugs improved assembled behavior and enhanced colloidal stability, and the developed nanoparticles possess tumor-specific imaging and chemotherapy with in vivo therapeutic feedback. Abstract: Self-assembled prodrug nanoparticles with tumor-responsive capacity have great potential in tumor visualization and treatment. …

A dynamic covalent polymeric antimicrobial, based on phenylboronic acid-installed micellar nanocarriers incorporating vancomycin and curcumin, was developed to overcome drug-resistant bacterial infections. Compared with monotherapy, this antimicrobial displayed more significant eradication of drug-resistant bacteria in vitro and in vivo. This work could become a universal platform to combat the ever-threatening drug-resistant infectious diseases. Abstract: Increasing …

Functional nucleic acid engineered double-barreled nanopores were designed and applied for measuring Na/K ratio (RNa/K) at single-cell level. The applicability of this nanotool is validated by practical probing intracellular RNa/K during the drug-induced primary stage of apoptotic volume decrease. Especially, the RNa/K has been shown by our nanotool to be different in cell lines with different metastatic …
