Bioinspired Microactuators Fabricated via One-step Meniscus-guided 3D Nanoprinting
Seong-Jae Eom, Vasanthan Devaraj, Sunghyun Kwak +4
We introduce a bioinspired microactuator fabricated via a one-step meniscus guided 3D nanoprinting technique. This technique directly produces a freestanding three dimensional comp…

Spatially Uniform and Defect-Tolerant Plasmonic Responses in 3D printed Gold Nanoparticle Assemblies
Vasanthan Devaraj, Sunghyun Kwak, Hyeongjip Kim +4
Three-dimensional (3D) assemblies of gold nanoparticles (AuNPs) offer a rich platform for plasmonic coupling and near-field engineering, yet their optical behavior is often complex…
