研究目的
To develop a novel photo-controlled thermosensitive electrochemiluminescence hydrogel (PT-ECL hydrogel) sensing platform for the detection of isocarbophos (ICP) with specificity, simplicity, and precise controllability.
研究成果
The PT-ECL hydrogel sensing platform demonstrated high sensitivity and specificity for ICP detection, with a low detection limit and wide linear range. The integration of AuNRs as photothermal converters enabled precise control over the hydrogel's phase change, offering a novel approach for hydrogel-based assays.
研究不足
The study is limited by the specificity of the split aptamers to ICP and the dependency on the photothermal effect of AuNRs for signal amplification. Potential areas for optimization include the expansion of target analytes and improvement of hydrogel stability under varying conditions.
1：Experimental Design and Method Selection:
The PT-ECL hydrogel was designed by integrating Ru(bpy)3 2+ derivatives, split aptamers, and Au nanorods into a pNIPAM matrix. The methodology involved free radical polymerization for hydrogel synthesis and the use of AuNRs as photothermal converters.
2：Sample Selection and Data Sources:
The model target was isocarbophos (ICP), and the study utilized synthesized hydrogels and AuNRs for experiments.
3：List of Experimental Equipment and Materials:
Materials included N-isopropylacrylamide, ammonium persulfate, N,N'-Methylenebis acrylamide, chloroauric acid, sodium borohydride, and oligonucleotides. Equipment included SEM, TEM, UV-vis spectrometer, FT-IR spectrometer, and ECL emitter.
4：Experimental Procedures and Operational Workflow:
The synthesis of T-ECL hydrogel, preparation of Apt2 modified AuNRs, fabrication of different hydrogel modified electrodes, and ECL measurements were conducted under optimized conditions.
5：Data Analysis Methods:
ECL intensity changes were analyzed to determine ICP concentration, with statistical techniques applied for sensitivity and specificity evaluation.
