Summary: This work presents a PRET-based sensing strategy for ultrasensitive detection of nitric oxide (NO) in living cells. The supramolecular cyclodextrin modified on gold nanoparticles (GNPs) served as the PRET nanosensors, where NO-reactive molecules were inserted into the cyclodextrin cavity to form host-guest structures. The presence of NO triggered a reaction that generated rhodamine, causing a decrease in the scattering intensity of the GNPs and providing a sensitive detection of NO concentration. This sensing platform allows quantitative detection of NO and single-particle imaging analysis in living cells, providing great potential for in vivo sensing of biomolecules and metabolic processes.

Summary: This study experimentally investigated the growth of one-dimensional fiber-like structures and found that there was no significant correlation between fiber length and growth rate. This suggests that the low size dispersities characteristic of living crystallization-driven self-assembly processes do not result from a gradual reduction in growth rate with fiber length, supporting the previously proposed explanation based on an analogy with living covalent polymerizations of molecular monomers.

Summary: Living crystallization-driven self-assembly (CDSA) enables the formation of uniform fiber-like micelles with precise length/composition. The kinetic stability of formed micelles is crucial for realizing the living characteristic of CDSA. In this study, a series of block copolymers with different chain lengths were synthesized to investigate the influence of chain length and solvent on the kinetic stability and self-seeding behaviors of micelles. The results showed that the micelles could be kinetically frozen and the elongation mechanism varied depending on the chain length and solvent polarity.

Summary: In this study, a novel nanometal surface energy transfer (NSET) nanoruler with a single-nucleobase resolution was proposed for in situ identification of aptamer-binding targets on living cell membrane surfaces. The nanoruler consisted of FAM-labeled aptamers and single-sized gold nanoparticle (GNP) antibody conjugates as a donor and an acceptor, respectively. Experimental evidence demonstrated the single nucleobase resolution of the nanoruler by molecular size, orientation, quenching nature, and other dye-GNP pairs. The nanoruler showed high reproducibility and precision for measuring molecule distance on living cell membranes at the nanometer level due to the use of only single-sized antibody-capped GNPs. The proposed strategy represents a solid step towards the wider application of optical-based rulers for observing molecular structural configuration and dynamic transitions on the membrane surface of living cells.

Summary: Nanoporous silver films (npAgF) can be fabricated using plasma treatments, which offer a simpler and greener approach compared to traditional methods. A wrinkled npAgF (w-npAgF) was successfully prepared using a thermally contractible polystyrene substrate, and it showed significantly higher SERS enhancement compared to flat npAgF. The w-npAgF could be reused for multiple SERS measurements after mild plasma treatments, demonstrating its potential as a low-cost and reusable 3D SERS substrate.

Summary: The magnetization of Zn1-xCoxO (0.0055 <= x <= 0.073) nanoparticles was measured as a function of temperature and magnetic field. The magnetic properties were found to be derived from the antiferromagnetic spin clustering of Co2+ nearest-neighbors. The magnetization curves showed a deviation from the expected behavior below 6 K, which was successfully explained by a model based on single-ion anisotropy and randomly oriented nanoparticles.

Summary: This study aims to evaluate the transport properties and CBZ adsorption capacities of PES/mesoparticles-based MMMs in aqueous solutions with different physicochemical characteristics. The results show that PES/SH-MCM-41-based MMMs have the highest potential for CBZ adsorption. The multivariate design results indicate that contact time, initial CBZ concentration, and the amount of SH-MCM-41 incorporated in MMM significantly influence the adsorption capacity, while pH does not affect it. Water permeability tests show a correlation between the H2O permeability and the porosity of the synthesized membranes. PES/SH-MCM-41-based MMMs exhibit high porosity and good ability to remove CBZ from water, regardless of the pH of the aqueous solutions.

Summary: An experimental setup was designed and assembled to evaluate the permeation of gaseous species and collect electrochemical impedance spectroscopy data in disk-shaped ceramic membranes. The setup consisted of an alumina sample holder with thermocouple tips and platinum electrodes located close to both sides of the sample. Gas permeation through a ceramic membrane was monitored using mass flow controllers, a mass spectrometer, and an electrochemical impedance analyzer. Ceramic composite membranes were prepared with the infiltration of molten eutectic compositions of alkali salts into porous gadolinia-doped ceria for testing and data validation. Values of the alkali salt melting points and the permeation rates of carbon dioxide, in agreement with reported data, were successfully collected.
