研究目的
To develop an ultrasensitive single-antibody MIP-ECL immunosensor for the detection of diethylstilbestrol (DES) using MMIPs as alternatives for biometric molecules and CdTe@ZnS-Ru@SiO2 luminescence probes for signal amplification.
研究成果
The developed MIP-ECL immunosensor demonstrates high sensitivity, specificity, and stability for DES detection, with a detection limit of 0.025 pM. The use of MMIPs as capture probes and CdTe@ZnS-Ru@SiO2 luminescence probes represents a novel approach to biosensor construction, offering advantages in terms of cost, stability, and operational simplicity.
研究不足
The study does not explicitly mention limitations, but potential areas for optimization could include further improving the sensor's specificity and stability under various environmental conditions.
