Imprint Lithography-Based, Multimodal Contrast Agents and the Effect of Shape and Size on Biodistribution

Herlihy K.P., Merkel T.J., DeSimone J.M., UNC Chapel Hill, US

Polymer research and modern medicine are at a critical juncture. Many state of the art, small molecule therapeutics are difficult to deliver effectively because of poor solubility and rapid elimination by the reticuloendothelial system. In [...]

Utilizing PRINTTM Technology to Create Precision Nanopatterned Films

Denison Rothrock G., Rolland J., Henn R., Liquidia Technologies, US

We describe the use of a new, enabling class of materials for performing precise, nano-scale imprint lithography for patterned film replication. These low surface energy, minimally adhesive, room-temperature photocurable perfluoropolyether (PFPE) elastomers, trademarked as Liquidia’s [...]

Fabrication of Perforated Membranes in Polymers by Imprint Lithography

Roychowdhury A., Park S., Louisiana State University, US

The ability to imitate architecture of naturally existing systems in an economical way is important because this will provide platform for various fundamental and applied research activities. One such structure is a perforated membrane having [...]

FEM Simulation for demolding process in thermal imprint lithography

Song Z., Lee J., Park S., Louisiana State University, US

Thermal imprint lithography is a highly potential technique utilizing molding to produce micro- and nano-structures with high throughput and at low cost. Extensive researches have been performed in understanding polymer flow behavior and cavity filling [...]

Scalable Fabrication of Polymeric and Organic Nanomaterials using Particle Replication in Non-wetting Templates (PRINT) and Imprint Lithography

Maynor B.W., Denison G.M., Rolland J.P., DeSimone J.M., Liquidia Technologies, US

We have developed scalable, “top-down” nanofabrication methodologies for the fabrication of polymeric and organic nanostructures for nanobiotechnology and materials engineering. These techniques use novel perfluoropolyether (PFPE) elastomers that possess superior nanoimprinting properties, including error-free nanoscale [...]
