Summary: A label-free electrogenerated chemiluminescence (ECL) aptasensing method was developed for highly sensitive determination of dopamine (DA) based on target-induced DNA conformational change. The method utilizes the hybridization of an anti-DA specific aptamer with a capture ss-DNA to form a self-assembled ds-DNA on a gold electrode, which acts as an ECL biosensing platform. The presence of DA induces DNA conformational change, resulting in the release of intercalated Ru(phen)32+ and a decrease in ECL intensity. By combining specific recognition and amplification with ds-DNA, this method provides a promising strategy for simple, sensitive, and selective DA assay.

Summary: A flexible electrochemiluminescence (ECL) hydrogel sensor with good self-healing was developed using a transparent self-healing oxidized sodium alginate/hydrazide polyethylene glycol (OSA/PEG-DH) hydrogel. The hydrogel was created through crosslinking acylhydrazone bond and was catalyzed by 4-amino-DL-phenylalanine to enable rapid gelation and self-healing. The ABEI/IL/OSA/PEG-DH hydrogel, obtained by immobilizing 2-hydroxy-N,N,N-trimethylethanaminium chloride and N-(aminobutyl)-N-(ethylisoluminol) (ABEI) in the OSA/PEG-DH hydrogel, was used as a semi-solid electrolyte for the flexible ECL hydrogel sensor. This research provides new insights into the development of flexible ECL sensors for bioanalytical applications.

Summary: This study reports a simple, low-cost, green, and mild method for preparing three-dimensional nanocomposite materials of gold nanorods (Au NRs)@TiO2. The Au NRs were coated with TiO2 through in situ reduction at room temperature without complicated operations. The synthesized Au NRs@TiO2 nanocomposites were used as surface-enhanced Raman spectroscopy (SERS) active substrates for sensitive and reusable detection of environmental pollutants. The results showed that the pollutants on Au NRs@TiO2 nanocomposites exhibited higher SERS activity and reproducibility compared to those on Au NR substrates without TiO2. In addition, the SERS substrate could be easily recycled by UV-assisted self-cleaning to remove residual analyte molecules. Malachite green (MG) and crystal violet (CV) were used as examples to demonstrate the feasibility of the proposed sensor for sensitive detection of environmental pollutants. The results showed that the limit of detections (LODs) for MG and CV were 0.75 μg/L and 0.50 μg/L, respectively, with recoveries ranging from 86.67% to 91.20% and 83.70% to 89.00%. Furthermore, the SERS substrate maintained its high SERS enhancement effect even after three cycles of use, indicating the potential of the method for detecting MG and CV in complex samples. The proposed sensor, with its high sensitivity, reusability, portability, and rapid detection capability, could have potential applications in on-site detection of environmental pollutants in complex sample matrices.
