  • Understanding molecular recognition is essential to biological and material applications. Surface-specific techniques based on second order nonlinear optical processes such as second harmonic generation (SHG) and sum frequency generation (SFG) are able to selectively study biological events occurring at the interface. We used SFG to probe the Phospholipase D induced hydrolysis reaction of symmetric lipid bilayer supported on a planar silica surface. The χ(3) SHG technique was used as a complementary technique to monitor the reaction due to changes in interfacial potential of the bilayer after hydrolysis.
    Based on our group’s previous work, isothermal turnover can be achieved in DNA-templated ligation reactions using destabilizing modifications to the DNA. This system was applied to the detection of target sequences specific to the Hepatitis B virus. The generality of lesion-induced isothermal DNA amplification was also expanded to RNA detection.
