Peptide nucleic acid containing azobenzene (N-PNA) was covalently bound on chip surfaces. Complementary DNA probes labeled by gold nanoparticles hybridizated with PNA on chip surfaces. The hybridization was successful...
Adsorption of 4-(4-nitrophenylazo)-1-naphthol (NPAN), an azobenzene derivative, on Au(111) has been in-vestigated in aqueous HClO4 solution by using the cyclic voltammetry and scanning tunneling microscopy (STM). The ...

The micropattern observed in the amorphous azobenzene polymer film by degenerated four-wave mixing has been reported. Patterns with well-defined structures are examined with the scanning electron microscopy and the po...
THE electrochemical and/or photochemical active organic molecules have attracted much atten-.tion due to their potential applications in the field of molecular electronics. The azobenzenederivatives have been widely s...
THE self-assembled monolayers (SAMs) emerged in the last decade as one of the most convenient and useful methods of preparing molecularly tailored interfaces with controlled spatial and geometric constraints, and have...
Optical phase conjugation is a technique that employs nonlinear optical effects to precisely reverse both the direction of the propagation and the overall phase of a wavefront. It may be used in a variety of spheres, ...
