We explore the potential applications of localized surface plasmon resonances (LSPRs) to investigate mid-infrared chiroptical response of Al-doped ZnO (AZO)-based nanostructures embedding layers of chiral pharmaceutical drug solutions to develop novel chir ...

We investigate the mid-infrared chiroptical response of plasmonic nanostructures based on Al-doped ZnO and layers of an aqueous solution of Ladarixin, a chiral pharmaceutical currently under clinical trial for the treatment of type 1 diabetes. We explore t ...

The demand for continuous monitoring of biochemical markers for diagnostic purposes is increasing as it overcomes the limitations of traditional intermittent measurements. This study introduces a method for long-term, continuous plasmonic biosensing of oli ...

Biosensors are indispensable tools for public, global, and personalized healthcare as they provide tests that can be used from early disease detection and treatment monitoring to preventing pandemics. We introduce single-wavelength imaging biosensors capab ...

The present invention relates to a plasmonic biosensor system. The system includes a nano-hole array device comprising at least one nano-hole array (NHA) including at least one or a plurality of nano holes (NH), an image sensor (A3) for capturing light pro ...

An innovative nanoplasmonic biosensor was presented for real-time label-free monitoring of cytokine secretion at single-cell resolution. This biosensor is integrated with a uniquely designed microfluidic device that provides a microchamber for cell incubat ...

We demonstrate a handheld on-chip biosensing technology that employs plasmonic microarrays coupled with a lens-free computational imaging system towards multiplexed and high-throughput screening of biomolecular interactions for point-of-care applications a ...

We analyze surface plasmon polaritons at noble metal interfaces for enhancing chiroptical sensing of dilute chiral drug solutions. Circular dichroism is amplified by plasmonic resonances to attain sensitivity to nano-scale drug volumes, demonstrating great ...

We present a nanophotonic method capable of detecting mid-infrared molecular fingerprints without the need for spectrometry, frequency scanning, or moving mechanical parts. We leverage dielectric metasurfaces featuring ultra-sharp resonances each tuned to ...

The misfolding of proteins from native monomers into β-sheet-rich fibrils via oligomers is a key hallmark of neurodegenerative diseases (NDDs). Identifying and screening drugs that inhibit protein aggregation for early disease intervention remains challeng ...

Nature Photonics spoke with Hatice Altug, from the & Eacute;cole Polytechnique F & eacute;d & eacute;rale de Lausanne (EPFL), Thomas Krauss, from the University of York, and Malini Olivo from the Agency for Science, Technology and Research (A*STAR) about o ...

We investigate plasmon-enhanced optical rotation and circular dichroism in a near-zero-index metamaterial composed of metallic nanospheres randomly dispersed in a chiral drug solution. ...

The advent of nanotechnology has allowed scientists to study light–matter interactions at the nanoscale. A considerable amount of fundamental knowledge has accumulated in the past two decades and the field of nano-optics may now in fact be on the cusp of d ...
