Plasmon-induced near-infrared fluorescence enhancement of single-walled carbon nanotubes
Ardemis Anoush Boghossian, Giulia Tagliabue, Sayyed Hashem Sajjadi, Alessandra Antonucci, Shang-Jung Wu, Theodoros Tsoulos, Amirmostafa Amirjani
Single-walled carbon nanotubes (SWCNTs) emit near-infrared (NIR) fluorescence that is ideal for optical sensing. However, the low quantum yields diminish the sensor’s signal-to-noise ratio and limits the penetration depths for in vivo measurements. In this ...
2022Low-Loss Anisotropic Image Polaritons in van der Waals Crystal alpha-MoO3
Orthorhombic molybdenum trioxide (alpha-MoO3), a newly discovered polaritonic van der Waals crystal, is attracting significant attention due to its strongly anisotropic mid-infrared phonon-polaritons. At the same time, coupling of polariton with its mirror ...
WILEY-V C H VERLAG GMBH2022Nanophotonic biosensors harnessing van der Waals materials
Low-dimensional van der Waals (vdW) materials can harness tightly confined polaritonic waves to deliver unique advantages for nanophotonic biosensing. The reduced dimensionality of vdW materials, as in the case of two-dimensional graphene, can greatly enha ...

Metasurfaces have emerged as a breakthrough platform for manipulating light at the nanoscale and enabling on-demand optical functionalities for next-generation biosensing, imaging, and light-generating photonic devices. However, translating this technology ...
2021Hot carrier-mediated avalanche multiphoton photoluminescence from coupled Au–Al nanoantennas
Avalanche multiphoton photoluminescence (AMPL) is observed from coupled Au–Al nanoantennas under intense laser pumping, which shows more than one order of magnitude emission intensity enhancement and distinct spectral features compared with ordinary metall ...
2021Distinguishing dopamine and calcium responses using XNA-nanotube sensors for improved neurochemical sensing
Ardemis Anoush Boghossian, Melania Reggente, Alice Judith Gillen, Alessandra Antonucci, Daniel Eduardo Morales Garza
To date, the engineering of single-stranded DNA-SWCNT (DNA-SWCNT) optical biosensors have largely focused on creating sensors for new applications with little focus on optimising existing sensors for in vitro and in vivo conditions. Recent studies have sho ...
2021Fabrication of Sub-10-nm Plasmonic Gaps for Ultra-Sensitive Raman Spectroscopy
Hatice Altug, Arif Engin Cetin
The past two decades have witnessed the explosion of activities in the field of surface enhanced Raman spectroscopy (SERS). SERS platforms employ nano-structures that excite plasmonic modes with large local electromagnetic fields localized within small gap ...
SPRINGER2020Polariton relaxation and polariton nonlinearities in nonresonantly cw-pumped III-nitride slab waveguides
Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Gordon Jens Callsen, Joachim Armand Simonne Ciers
Polariton lasers are mostly based on planar cavities. Here we focus on an alternative configuration with slab waveguide modes strongly coupled to excitons confined in GaN/AlGaN quantum wells. We study experimentally and theoretically polariton relaxation a ...
2020Transport of hot carriers in plasmonic nanostructures
Plasmonic hot carrier devices extract excited carriers from metal nanostructures before equilibration and have the potential to surpass semiconductor light absorbers. However their efficiencies have so far remained well below theoretical limits, which nece ...
AMER PHYSICAL SOC2019A Unified View on Nanoscale Packing, Connectivity, and Conductivity of CNT Networks
The design of functional structures from primary building blocks requires a thorough understanding of how size, shape, and particle-particle interactions steer the assembly process. Specifically, for electrically conductive networks build from carbon nanot ...
