Summary: A dual-mode DNA logic gate based on gas pressure biosensing and lateral flow assay was developed for the intelligent detection of multiple microRNAs. The gate utilized platinum-coated gold nanoparticles as a signal reporter for dual-signal readout. The miRNAs initiated the cyclic strand displacement reaction to enrich a large amount of nanoparticles, which could be visually detected on a lateral flow strip. Additionally, the nanoparticles catalyzed the decomposition of H2O2 to generate gas pressure, which could be measured by a handheld gas pressure meter.

The biosensor relies on the color change of gold nanoparticles induced by NaCl after incubation with bacteria and aptamer binding. The optimized conditions for detection were found to be 5 μM aptamer concentration and 200 mM of NaCl. The detection limit for P. aeruginosa was 10(5) CFU mL(-1) by the naked eye and 10(4) CFU mL(-1) by UV-Vis spectrometry.

Summary: In this study, CdS/TiO2:Cu hollow spheres with highly dispersed heterointerfaces were successfully constructed for photoreduction of CO2 in the presence of in situ generated H2S. The production rates of CO and H2 significantly increased due to the consumption of photo-generated holes and large production of protons by H2S decomposition. Moreover, the remediation of photocorroded CdS by H2S extended the service life of the heterojunction.

Summary: Revealing multiple biomolecules simultaneously in biological and biomedical research is challenging due to their low abundance and poor ionization efficiency. Mass spectrometry (MS) offers unique advantages in multiplexed and label-free analyses, but direct MS profiling of these biomolecules remains difficult. A potential solution to this issue is the use of mass tag (MT)-encoded nanointerfaces, which convert the abundance or activity of biomolecules into amplified ion signals, enabling synchronous MS analysis of multiple targets. This review provides a comprehensive overview of recent advances in MT-encoded nanointerfaces for multiplexed MS bioanalysis and biomedical research, covering their structural characteristics, applications in biomarker assays, cell analysis, and tissue imaging, as well as future prospects.

Summary: We prepared self-assembled DNA nanowires with lengths of 30-120 nm using structural DNA nanotechnology and measured the transport current in these nanowires by plugging individual gold nanoparticles into a circuit. Contrary to previous reports, we observed a significant current attenuation with increasing nanowire length, confirming the prediction of the incoherent hopping model. We also proposed a mechanism for the reversible regulation of charge transport in DNA nanowires involving dynamic transitions in steric conformation.
