With the recently‐booming hydrogen (H2) economy by green H2 as the energy carriers and the newly‐emerged exhaled diagnosis by human organ‐metabolized H2 as a biomarker, H2 sensing is simultaneously required with fast response, low detection limit, and tolerant stability against humidity, switching, and poisoning. Here, reliable H2 sensing has been developed by utilizing indium oxide nanocubes decorated...
Hydrogen (H2) sensing materials such as semiconductor metal oxides may suffer from poor long‐term stability against humidity and unsatisfactory selectivity against other interfering gases. To address the above issues, highly stable and selective H2 sensing built with palladium oxide nanodots decorating aluminum oxide nanosheets (PdO NDs//Al2O3 NSs) has been achieved via combined template synthesis,...
Understanding the dynamic behavior of a nanostructure translocating through a nanopore is important for various applications. In this paper, the characteristics in ion current traces of tetrahedral DNA nanostructures (TDN) translocating through a solid‐state nanopore are examined, by combined experimental and theoretical simulations. The results of finite element analysis reveal the correlation between...
Hydrogels are emerging biomaterials with desirable physicochemical characteristics. Doping of metal ions such as Ca2+, Mg2+, and Fe2+ provides the hydrogels with unique attributes, including bioactivity, conductivity, and tunability. Traditionally, this doping is achieved by the interaction between metal ions and corresponding ligands or the direct incorporation of as‐prepared metal‐based nanoparticles...
Targeted and sustained delivery of drugs to diseased tissues/organs, where body fluid exchange and catabolic activity are substantial, is challenging due to the fast cleansing and degradation of the drugs by these harsh environmental factors. Herein, a multifunctional and bioadhesive polycaprolactone‐β‐cyclodextrin (PCL‐CD) polymersome is developed for localized and sustained co‐delivery of hydrophilic...
