Tissue nanotransfection is a novel biotechnology, and we employed a cell-arraybased model and a multilayer-stack-based model to simulate and illustrate the DNA delivery process across the skin tissue via the Si hollow needle array-based chip at nano and micro scales. It was found that a moderate electric field of about 150 V/mm can effectively deliver DNA with a balance between the delivery efficiency and safety concerns.

To improve cancer immunotherapy by eliciting pyroptosis, we reasonably designed and constructed a nanoplatform (CANPs) integrating the heat shock protein 90 inhibitor tanespimycin (17-AAG) with the photosensitizer chlorin e6 (Ce6) to simultaneously target the tumor. CANPs efficiently boosted anti-tumor immune responses and suppressed tumor growth, thereby extending the survival of 4T1 breast tumors-bearing mice.

With the phosphorus covered, the CO intermediates on the surface may be rapidly protonated to produce CHO* rather than being desorbed from the catalyst surface to form CO molecules, the selectivity of CO2 reduction to CH4 on TiO2 can be greatly enhanced.

Absorption amplification has been realized utilizing multiple-beam interference in 20-nm Ga2O3 optical cavity. Based on the high absorption efficiency and short carrier transmission distance of ultra-thin Ga2O3, an ultra-sensitivity flexible solar-blind photodetector array is developed. The device can execute the functions of imaging, spatial distribution of light source intensity, and realtime light trajectory detection.

Highly dispersed Co-based nanoparticles encapsulated into porous N-doping carbon polyhedral with the low content of Ru modification (LRu@HDCo-NC) are designed through pyrolysis of Co/Zn zeolitic imidazole frameworks (ZIFs) containing Ru-based ligands and used as cathode for lithium (Li)-O2 batteries. LRu@HDCoNC can effectively inhibit side reactions and show superior catalytic performance which makes Li-O2 batteries display high capacity, low overpotential, and long life.

A highly efficient single-atom catalyst Au-SA/FeOOH was facilely synthesized via deposition−precipitation process. The combination of porous metal oxide support and highly active single-atom Au can dramatically promote the activation and fixation of dinitrogen (N2) to achieve a ammonia (NH3) yield of 2,860 μg·h−1·mgAu−1 under ambient conditions.
