Tumor acidity is a key driver of cancer progression and a promising target for early diagnosis and therapy. However, existing approaches remain limited in their ability to sensitively and specifically visualize and quantify tumor acidity in...
Orthogonal Aptamer-Lectin Co-Recognition Enables Sandwich-Type Assays for Glycoproteins [0.03%]
正交型适配体-凝集素协同识别介导糖蛋白的夹心型检测
Dinghui Xiong,Yunyan Ren,Jimmy Gu et al.
Dinghui Xiong et al.
Sandwich assays are widely used for protein detection, but aptamer-based formats are constrained by the difficulty of identifying two high-affinity aptamers that bind distinct, nonoverlapping epitopes on the target. Here, we present an orth...
A pH-Calibrated Multi-Analyte MXene Aerogel Electrochemical Platform Assisted by Interpretable Machine Learning for CSF-Based Prescreening of Postoperative Bacterial Meningitis [0.03%]
