Gold nanoparticles have been used in biomedical applications since their first colloidal
syntheses more than three centuries ago. However, over the past two decades, their …

Dip-pen nanolithography (DPN) is a nanofabrication technique that can be used to directly
write molecular patterns on substrates with high resolution and registration. Over the past …

The ability to tailor the chemical composition and structure of a surface on the 1–100 nm
length scale is important to researchers studying topics ranging from electronic conduction …

The ability to organize matter on the nanometer scale is one of the major enabling principles
in the field of nanotechnology. Scanning probe microscopy (SPM) has been a key tool in …

Self-assembled monolayers are a unique class of nanostructured materials, with properties
determined by their molecular lattice structures, as well as the interfaces with their substrates …

A novel photochemical method for the synthesis of fluorescent Au nanodots (size≈ 1.2 nm)
is proposed (see image). The results clearly demonstrate that reduced graphene oxide …

Historically, measurements have been made by taking a sample and analyzing it for a single
analyte. When multiple analytes must be measured from a single sample, the sample …

The fabrication of arrays of sub-50-nm gold dots and line structures with deliberately
designed 12− 100-nm gaps is reported. These structures were made by initially using dip …

Tetraphenyl porphyrin substituted deoxyuridine was used as a building block to create
discrete multiporphyrin arrays via site specific incorporation into DNA. The successful …
