Abstract

Abstract

En 中文
• A fluorescent aptasensor was developed for sensitive Aβ oligomer detection. • Apt-Ini@MBs enabled target recognition and matrix interference removal. • CHA enabled enzyme-free signal amplification with a detection limit of 4.1 pg mL-1. • The proposed platform was successfully applied to plasma sample analysis.
