Abstract
We have examined real-time,in situhybridization detection of target DNA (tDNA) in a buffer solution and in urine using 8 μm-thick lead magnesium niobate–lead titanate (PMN–PT) piezoelectric plate sensors (PEPSs) with improved 3-mercaptopropyltrimethoxysilane (MPS) insulation and a new multiple-parabola (>50) resonance peak position fitting algorithm.
