Accurate and sensitive detection of Pax-5a gene is the basis of early diagnosis and prediction of acute leukemia. This research aims to develop a universal dual-mode sensing method enables ultrasensitive gene detection based on smart control of DNA amplification by nucleic acid beacons e to form programmed dendrimer. The Pax-5a target gene triggers the opening of smart gate hairpin probe (Hp), exposing the stem sequence as the primer to bind with padlock probe for rolling circle amplification (RCA).

The transition from insulator to electro-responsive has been successfully achieved by earlier studies for some inorganic materials by applying external stimuli that modify their 3D and/or electronic structures. In the case of insulating polymers, this transition is frequently accomplished by mixing them with other electroactive materials, even though a few physical treatments that induce suitable chemical modifications have also been reported. In this work, a smart approach based on the application of an electro-thermal reorientation process followed by a charged gas activation treatment has been developed for transforming insulating 3D printed polymers into electro-responsive materials.

By integrating iron-cobalt squarate bimetallic metal-organic framework (Fe-Co-SqBMoF) based smart material (SM) with functional DNA (fDNA), we designed a target responsive fDNA@Fe-Co-SqBMoF bioelectrode that exhibits recognition induced switchable response to serve as a reagentless single step electrochemical apta-switch (REA). The construct takes advantage of fDNA ability to bind and concentrate target on the receptor interface, while Fe-Co-SqBMoF@SM multifeatures to serve as an immobilization matrix and a signal generating electrochemical switch. Fe-Co-SqBMoF was introduced to prepare a redox active pencil graphite electrode (PGE), while fDNA (aptamer) was decorated on the receptor PGE to impart specificity and selectivity.

The electrochemical conversion of carbon dioxide (CO) into hydrocarbon products emerges as a pivotal sustainable strategy for carbon utilization. Cu-based catalysts are currently prioritized as the most effective means for this process, yet it remains a long-term goal to achieve high product selectivity at elevated current densities. This study delved into exploring the influence of a topological poly(2-aminoazulene) with a substantial dipole moment on modulating the Cu surface dipole field to augment the catalytic activity involved in CO reduction.

With increasing awareness of environmental protection, additional attention has been given to environmentally friendly metal anticorrosion research. In this paper, the green organic corrosion inhibitor sodium lignosulfonate (SLS) was extracted from bagasse waste, and a Ce-MOF@SLS smart anticorrosive film containing the inhibitor was prepared on the surface of an aluminum alloy by in situ electrodeposition. The material was characterized by SEM, EDS, FT-IR, XRD and XPS, and its corrosion resistance was tested with EIS and neutral salt spray tests.
