“…As a consequence, linear detection of target substrates is improved from 5 × 10 −3 m to 156 × 10 −3 m , because the oxidase kinetics became no oxygen limited. Based on this mechanism, they also fabricated a biocatalytic membrane with up to 80 times improvement in catalytic efficiency . Similarly, applying the Janus configuration in photocatalytic membrane reactors can improve the degradation efficiency of semiconductor photocatalysts by facilitating oxygen diffusion to the catalyst surface ( Figure a,b).…”

Membranes are recognized as a key component in many environment and energy-related applications, but conventional membranes are challenged to satisfy the growing demand for ever more energy-efficient processes. Janus membranes, a novel class with asymmetric properties on each side, have recently emerged and represent enticing opportunities to address this challenge. With an inner driving force arising from their asymmetric configuration, Janus membranes are appealing for enhancing energy efficiency in a variety of membrane processes by promoting the desired transport. Here, the fundamental principles to prepare Janus membranes with asymmetric surface wettability and charges are summarized, and how they work in conventional and unconventional membrane processes is demonstrated.

Owing to their unique physicochemical properties and comparable size to biomacromolecules, functional nanostructures have served as powerful supports to construct enzyme-nanostructure biocatalysts (nanobiocatalysts). Of particular importance, recent years have witnessed the development of novel nanobiocatalysts with remarkably increased enzyme activities. This review provides a comprehensive description of recent advances in the field of nanobiocatalysts, with systematic elaboration of the underlying mechanisms of activity enhancement, including metal ion activation, electron transfer, morphology effects, mass transfer limitations, and conformation changes. The nanobiocatalysts highlighted here are expected to provide an insight into enzyme-nanostructure interaction, and provide a guideline for future design of high-efficiency nanobiocatalysts in both fundamental research and practical applications.Catalysts 2020, 10, 338 2 of 15 nanoscale supports, such as nanoparticles, nanowires, microspheres, metal-organic frameworks, and nanoflowers, has also drawn extensive attention in recent years [5,[16][17][18][19][20][21][22]. A great deal of effort has also been made to design nanostructured supports with a variety of components including noble metal (e.g., Au) [23,24], metal oxides (e.g., Cu 2 O, Fe 3 O 4 , SiO 2 , Ti 8 O 15 , alumina) [16,25-33], polymer (e.g., Cu 2+ /PAA/PPEGA matrix, aldehyde-derived Pluronic polymer, polycaprolactone) [34-36], metal-organic frameworks (e.g., zeolitic imidazolate framework) [37-39], carbon based (e.g., carbon dots, carbon nanotubes) [40-44], and complex compounds (e.g., Cu 3 (PO 4 ) 2 ·3H 2 O, Ca 3 (PO 4 ) 2 , Co 3 (PO 4 ) 2 ·8H 2 O, Mn 3 (PO 4 ) 2 , Ca 8 H 2 (PO 4 ) 6 , Cu 4 (OH) 6 )SO 4 , CaHPO 4 , Zn 3 (PO 4 ) 2 , Mg-Al layered double hydroxide, CdSe/ZnS quantum dots) [17,[45][46][47][48][49][50][51][52][53][54][55][56][57][58][59]. These representative supports, which possess unique chemical and physical properties, such as controllable release of ion activator and synergic catalysts and response to external stimuli, are able to regulate the enzyme-support interaction and eventually lead to an unprecedented enhancement in immobilized enzyme activity [7,60,61].Overall, recent years have witnessed great success in the interactions between artificial nanostructured supports and natural enzymes for enhanced activity. This review will focus on recent advances in this field in the past 10 years, with an emphasis on various mechanisms behind the boosted catalytic activities, including reduced mass transfer limitation, interfacial ion activation, local heating effect, synergistic effects, conformational changes, substrate channeling and so on. A better understanding of the relationship between the characteristics of the nanostructured supports and the enhanced activities of nanobiocatalysts, may provide new insights in designing efficient nanobiocatalysts for various applications.

Bioinspired nanochannels for smart mass transport control have shown great potential for various applications in nanofluids, biosensing, and separation. Here, a nanochannel-based smart responsive platform exhibiting high formaldehyde (HCHO) sensitivity is designed and successfully fabricated by functionalizing the inner pore surface with ethylenediamine (EDA). By employing the nucleophilic addition reaction between HCHO and EDA immobilized on the nanochannels, the artificial nanochannels can switch from an open state to a closed state with the increase in HCHO. This is because the surface charge density and the wettability of the nanochannels change along with the HCHO immobilization. Meanwhile, the EDA-functionalized platform can hold a large amount of HCHO due to the abundant nanochannels of the membrane, so it presents a significant ability to remove HCHO in complex matrices. Also, the cultivation of mesenchymal stem cells in media containing HCHO can achieve excellent vitality in the presence of the EDA-functionalized nanochannels materials. This work paves an avenue for designing and developing bioinspired nanochannel based platform for harmful compounds detection and removal.
