Shape anisotropic colloidal particle fabrication using 2-photon polymerization

Two-Photon Polymerization Fabrication of Doped Microstructures

Nanocomposite Fabrication Through Particle Surface Initiated Polymerization

Magnetic nanoparticles (NPs) have attracted much interest due to their special physicochemical properties such as enhanced magnetic moment and coercivity different from the bulk and atomic counterparts. Incorporation of the inorganic NPs into a polymer matrix has extended the particle applications such as in high-sensitivity chemical gas sensors due to the advantages of polymeric nanocomposites...

Large-format fabrication by two-photon polymerization in SU-8

Microporous structures are central to many fields of science and engineering, but many of these systems are complex with little or no symmetry and are difficult to fabricate. We applied two-photon polymerization (2PP) and femtosecond laser direct-writing techniques to fabricate broadarea large-format 3D microporous structures (450 μm × 450 μm × 40 μm) in the epoxy-based photoresist SU-8. The ap...

One- and two-photon induced polymerization of methylmethacrylate using colloidal CdS semiconductor quantum dots.

The development of one- and two-photon induced polymerization using CdS semiconductor quantum dots (QDs) and amine co-initiators to promote radical generation and subsequent polymerization is presented. Two-photon absorption (TPA) cross-section measurements, linear absorption, and transmission electron microscopy are used to characterize the QDs. The effectiveness of the co-initiators in increa...

Fabrication and Characterization of Particle-based Inverted Colloidal Crystals

INTRODUCTION Each year, there are about 3 million musculoskeletal surgeries performed in the United States. Two primary therapeutic methods used to repair musculoskeletal damage, specifically concerning bone damage, are autografts and allografts. Autografting, involves removing bone material from a secondary site on the patient for implantation at the damaged site, while allografting encompasse...
