Summary: A new chemosensor RBA-IMS has been synthesized as a turn-on sensor for selective sensing of Al3+, Cr3+ and Fe3+. The replacement of hydrazine with ethylenediamine has been observed to significantly alter the sensing behavior. The probe does not exhibit any color or fluorescence in the absence of most cations, except for Al3+, Cr3+ and Fe3+. RBA-IMS turns pink when combined with these cations, showing strong absorption and fluorescence signals at specific wavelengths.

Summary: A novel colorimetric/fluorescent probe (AgNPs-GSH-Rh6G2) was prepared by linking silver nanoparticles (AgNPs) with rhodamine 6G derivative (Rh6G2) using glutathione (GSH) as a linker molecule. The probe exhibited significant fluorescence change and colorimetric response upon addition of copper ions. A colorimetric/fluorescence dual-mode detection method was developed based on this phenomenon to selectively detect copper ions. The probe showed good sensitivity with linear ranges of 0.10-0.45 mM for fluorescence detection and 0.15-0.65 mM for colorimetric detection, and the detection limits were 0.18 μM and 24.90 μM, respectively. The dual-mode probe also demonstrated satisfactory results in detecting copper ions in sediment samples.

Summary: This study presents a proof-of-concept for molecularly imprinted polymer (MIP) functionalized Bi2S(3)/Ti3C2TX MXene nanocomposites for dual-mode sensing of chlorogenic acid (CGA) using photoelectrochemical (PEC) and electrochemical (EC) techniques. The dual-mode sensor showed good selectivity, stability, and reproducibility, with low detection limits for both PEC and EC signals. The use of two different transduction mechanisms in the dual-response mode significantly improved the reliability and accuracy of detection compared to single-mode sensors.

Summary: In this study, conductive polymers (CPs) were coated on different MEMS lateral comb-drive resonator designs using an electrochemical polymerization technique for the first time in the literature. The integration of CPs with MEMS not only benefited the mechanical advantages of the lateral resonator but also utilized the optical, electrical, and functional properties of the CPs. The designed resonators were used to detect volatile organic compounds in open-air conditions, even in uncontrolled air conditions due to the differences in intermolecular interaction according to the polymer and VOCs structure.

Summary: A facile amperometric biosensor was developed using a Co/2Fe metal-organic framework (MOF) with oxidase mimicking properties for the detection of sialic acid (SA). The biosensor was constructed by immobilizing Co/2Fe MOF and N-acetylneuraminic Acid Aldolase (NANA-Aldolase) enzyme on a gold screen-printed electrode. The sensor showed a linear range of 0.02 mM-1.00 mM for SA concentration and a limit of detection of 0.026 mM. The developed biosensor was successfully applied for the detection of SA in GD3 ganglioside and HeLa cancer cell lines, providing a more practical and accurate system.

Summary: Minimally invasive approaches in cancer diagnosis, such as liquid biopsies using blood samples, provide valuable information about the tumor and its state. However, isolating and detecting markers in complex matrices is challenging. Advances in polymer synthesis have led to enhanced platforms for liquid biopsies analysis, improving biosensor performance through increased sensitivity, improved binding, and avoidance of non-specific interactions. Additionally, polymer-based materials aid in signal amplification for low-concentration targets. This technology plays an essential role in oncology and clinical biomedicine, as shown by its critical application in liquid biopsies diagnosis.

Summary: In this study, new multifunctional carbazole derivatives containing pyrene (PrCz) or dansyl (DnCz) moieties were synthesized and characterized. The optical and electrochemical properties of the conducting polymers P(PrCz) and P(DnCz) were investigated after electropolymerization. Spectroelectrochemical measurements showed that both polymer films exhibited transparent to green electrochromic behavior, with P(DnCz) film having higher optical contrast value and faster response time than P(PrCz) film. SEM analysis revealed that the surface of P(DnCz) film consisted of many spherical clusters on a rough structure.

Summary: Solar thermal fuels (STFs) have potential for clean and renewable solar energy utilization, with solid state STFs showing high potential for thermal applications. In this study, a photoactive monomer (Cz-AzoCN) containing azobenzene and carbazole was designed, and its thermal storage properties were investigated. The results showed that polycarbazoles with azobenzene pendant groups can serve as an effective thermal storage platform due to their functionality, light absorption, and rigid conjugated chain structure. Electropolymerization was used to quickly synthesize polymer films for radiation, and the synthesized polymer exhibited a higher energy storage density than the monomer due to enhanced light harvesting.
