Creation of cadmium sulfide nanostructures using AFM dip-pen nanolithography.
A dip-pen nanolithography (DPN) process capable of depositing nanoscaled structures of semiconducting CdS materials was developed by careful control of the reaction speed between the precursors. The new development expanded the scope of the powerful DPN process and provided more insight in the deposition mechanism. Features ranging from several hundreds of nanometers to sub-50 nanometers were g...

In recent years, SPM-based lithography has attracted great attention because of its simplicity and precise control of the structure and location. Many SPM lithography techniques based on mechanical scratching,1 anodization of Si surfaces,2 electrochemical decomposition of self-assembled monolayers,3 electric field-induced chemical reactions,4 electrochemical reactions in solution using electroc...
متن کاملDip-pen Nanolithography Process Control Using a Dual- Probe Afm
Dip-pen nanolithography (DPN) is a tip-based direct print technique widely used in nanofabrication applications. DPN is typically performed using Atomic force microscopes (AFM). In DPN, the nano-sized tip of the AFM is coated with a layer of ink molecules of interest, and traversed over a suitable substrate to print the desired pattern. Despite developments in recent years, DPN is still perform...
متن کامل"Dip-Pen" nanolithography
A direct-write "dip-pen" nanolithography (DPN) has been developed to deliver collections of molecules in a positive printing mode. An atomic force microscope (AFM) tip is used to write alkanethiols with 30-nanometer linewidth resolution on a gold thin film in a manner analogous to that of a dip pen. Molecules are delivered from the AFM tip to a solid substrate of interest via capillary transpor...
متن کاملProtein nanostructures formed via direct-write dip-pen nanolithography.
We report a tip modification strategy coupled with dip-pen nanolithography for depositing proteins on a surface. This methodology offers patterning capabilities on the scale of 45 nm to many micrometers length. The biorecognition properties of nanofeatures composed of immunoglobulin-gamma (IgG) were confirmed by reacting the array with gold nanoparticles coated with anti-IgG. Furthermore, a two...
