From meniscus-guided 3D nanoprinting to plasmonic sensing and bio-nano hybrid devices — the research areas of AMGL.
We develop an in-house meniscus-guided 3D nanoprinter that enables rapid and simple fabrication of three-dimensional nanostructures. Using colloidal nanoparticle inks — metals, carbon nanotubes, conducting polymers, and quantum dots — we build composite architectures such as Au nanotips, CNT–QD hybrid structures, and PEDOT:PSS microstructures for next-generation nanodevices.
Plasmonic nanostructures concentrate light into nanometer-scale volumes. We engineer nanogap structures — hole-sphere platforms, nanoparticle-on-mirror cavities, and self-assembled dimers with sub-5 nm gaps — for ultrasensitive, quantitative surface-enhanced Raman scattering (SERS) sensing and reliable on-site molecular analysis.
Semiconductor quantum dots are quantum light sources attracting significant attention for lighting, displays, quantum cryptography, and quantum computing. Combined with engineered nanostructures, quantum dots achieve improved signal quality in reproducibility and directionality, opening routes to high-performance optoelectronic devices.
By merging genetically engineered biological building blocks with semiconductor materials, we create functional structures that neither component could achieve alone. Our current focus is on integrating engineered biomaterials such as the M13 bacteriophage with quantum dots and plasmonic structures.
We develop nano-bio material-based biosensors — colorimetric arrays, electronic noses, and SERS platforms — in collaboration with clinical researchers for medical diagnostics. We also build soft composite microactuators, such as magnetite–PEDOT:PSS structures, via meniscus-assisted 3D printing.
