The interest in micro- and nano-devices based on biodegradable polymers for in vivo applications is growing rapidly and the key to these applications lies in the fashioning of features analogous to the size of cells. This paper presents fabrication techniques for leveraging micro- and nanostructures on biodegradable polymers. Innovative approaches such as replication molding, laser interference...

In order to keep up with the advances in nano-fabrication, alternative, cost-efficient lithography techniques need to be implemented. Two of the most promising are nanoimprint lithography (NIL) and stencil lithography. We explore here the possibility of fabricating the stamp using stencil lithography, which has the potential for a cost reduction in some fabrication facilities. We show that the ...

Abstract Nano-kirigami method enables rich diversity of structural geometries that significantly broaden the functionalities optical micro/nano-devices. However, methodologies various nano-kirigami are still limited and as a result, chiral structure has yet been pushed to limit for operation at visible wavelength region. Here, merits strategies comprehensively explored bio-inspired nano-cilia m...

A self aligned nano scale gap between multiple metal layers has been fabricated using a newly developed technique of controlled undercut and metallization (CUM), and applied for the assembly of an individual carbon nanotube (CNT). The new method enables conventional optical lithography to fabricate nano-gap electrodes and self aligned patterns with nano scale precision. Individual CNTs were ass...

Microand nano-scale manufacturing has been the subject of an increasing amount of interest and research effort worldwide in both academia and industry over the past 10 years. Traditional lithography-based technology forms the basis of silicon-based micro-electro-mechanical systems (MEMS) manufacturing, but also precision manufacturing technologies have been developed to cover micro-scale dimens...

The authors present the design and fabrication of a nanophotonic waveguide and photodetector integrated device by molecular self-assembly of nanocrystal quantum dots (QD) and two different nano-gap formation techniques, namely electromigration-induced break-junction technique and electron beam lithography nano-gap patterning. A QD waveguide with 50 nm width integrated with a nano-scale QD photo...

We have attempted to clarify possible domain-wall processes present in the recently reported large ballistic magnetoresistance effects in nano-contacts. To that effect we have used e-beam lithography applied to epitaxial Ni films to fabricate nano-bridges in more controlled geometry than electrochemical deposition. Our preliminary results indicate that magnetic domains do play a role in the mag...
