Abstract :
A DNA probe assembly was developed using barium strontium titanate (BST) grown on a gallium arsenide (GaAs) substrate, using pulsed laser deposition (PLD). To verify the binding of probe material to BST, Fourier transform infrared spectroscopy and attenuated total reflectance (FTIR-ATR) techniques were used. The binding of the DNA probe strand was verified using capacitance measurement. Using this probe, the existence of the second strand can be sensed.
