9 ¬RPQ ¬T ¬S P.C N.C R ¬P ST ¬Q (a) (b) The schematic diagram of theorem proving before (a) and after (b) hybridization. The immobilized probe DNA sequences on aldehyde-coated slide glass. Molecular recognition properties by the target molecules between the probe sequences.

10 Experimental Section Preparation of probe DNA
Preparation of Target DNA Hybridization probe & Target DNA Washing Confocal microscope detection

14 Discussion Confocal microscope 457~633 nm
Detection range dye & Non-overlapping emission wavelength Eqipment condition is break down now Microarray scanner (futher exp.) False positive signal ¬P and ¬S: non-complementary sequence Why (?) GC ratio
