Photoinduced surface potential change of bacteriorhodopsin mutant D96N measured by scanning surface potential microscopy
Article Abstract:
Atomic force microscopy (AFM) and scanning surface potential microscopy (SSPM) are used to measure the photoinduced surface potential differences of wild-type (WT) and mutant D96N bacteriorhodopsin (BR) membranes. The results have shown that the surface potentials are generated by photoformation of surface charges on the extracellular side of the membrane and higher surface potential correlated with a longer lifetime of the charges.

Finite element method simulation of the field distribution for AFM tip-enhanced surface-enhanced Raman scanning microscopy
Article Abstract:
The electric filed enhancement distributions encountered in atomic force microscopy tip-enhanced surface-enhanced Raman spectroscopy are simulated using a frequency-domain three-dimensional finite element method. The results of the simulation lead to the conclusion that the field enhancement changes by only a factor of two when the nanoparticle size changes from 10 to 80 nm.

Observation of single dinuclear metal-complex molecules using scanning tunneling microscopy
Article Abstract:
The use of a pulse-injection technique is reported to deposit the quantum-dot cellular automata (QCA) candidate molecule trans-[Cl(dppe)2Ru[C(triple bond)C]6Ru(dppe)2Cl] on a Au(111) surface. The isolated molecules are clearly observed with a submolecular 'dumbbell'-like structure in high-resolution scanning tunneling microscopy (STM) images.
