Interfacing artificial devices with the human brain is central goal of neurotechnology. Yet, our imaginations are often limited by currently available paradigms and technologies. Suggestions for brain-machine interfaces have changed over time, along technology. Mechanical levers cable winches were used to move parts during mechanical age. Sophisticated electronic wiring remote control arisen age, ultimately leading plug-and-play computer interfaces. Nonetheless, brains so complex that these visions, until recently, largely remained unreachable dreams. The general problem, thus far, most technology mechanically and/or electrically engineered, whereas a living, dynamic entity. As result, worlds difficult interface one another. Nanotechnology, which encompasses engineered solid-state objects integrated circuits, excels at small length scales single few hundred nanometers and, thus, matches sizes biomolecules, biomolecular assemblies, cells. Consequently, we envision nanomaterials nanotools as opportunities in alternative ways.

Genetic analysis methods are foundational to advancing personalized and preventative medicine, accelerating disease diagnostics, monitoring the health of organisms ecosystems. Current nucleic acid technologies such as polymerase chain reaction (PCR), next-generation sequencing (NGS), DNA microarrays rely on fluorescence absorbance, necessitating sample amplification or replication leading increased processing time cost.

We use fluorescence-detected spectroscopy measure indirectly differential absorption circularly polarized light monolayer optically active molecules functionalized nanodisk arrays. Importantly, antennas have spectrally-coincident resonances, our fluorescence technique allows us deconvolute from molecules. find enhanced signals depend on nanophotonic resonances good agreement with simulated density, while no signal is detected adsorbed featureless surfaces.
