Large-Area Silver Nanodimple Arrays for Ultrasensitive Molecular Beacon-Based DNA Sensing

Not Accessible

Your library or personal account may give you access

Abstract

We report a large-area nanoplasmonic device fabricated by nanosphere lithography for enhanced molecular beacon-based biosensing. The device enabled 20-fold fluorescence enhancement that led to ultrasensitive DNA sensing with the detection limit of 10 fM.
