Overcoming charge screening via porous nanostructures for attomolar microRNA detection

2025-09-05

Abstract excerpt

<title>Abstract</title> <p>Electronic biosensors offer a compact, integrable platform for real-time biomolecular detection, yet their performance is often limited by charge screening in physiological environments. Here, we report a porous ZnO/Al2O3 biosensor with grain boundary-engineered nanostructures that enables attomolar-level (0.5 aM) detection of microRNAs (miRNAs). The porous architecture forms spontaneou...
