Phased array antennas?
Oh I get it alright!
researchgate.net/figure/A-quant…

We are constructing optically coupled biosensors from microspheres and semiconductor quantum dots (QDs).
Detection will be accomplished through the resonance shift of whispering gallery modes (WGMs) in the microspheres as an analyte is adsorbed to the surface of the microsphere.
The use of QDs in such a system allows us to remotely couple to the biosensors with an external optical system. Because the QDs have a high quantum yield and a broad absorption band, the biosensors may be excited with a low light flux well outside the spectral detection region.
The resonant effect will permit sensitive detection due both to the WGM's narrow spectral linewidths as well as to multiple sampling as light circulates in the resonant cavity.
Detection is local to the microsphere surface as changes in index are sampled via the WGM's evanescent field outside the microcavity. Since the microspheres are smaller than many cells, we anticipate that the system will be useful in both in vitro and in vivo environments
In photometry, luminous flux or luminous power is the measure of the perceived power of light.
It differs from radiant flux, the measure of the total power of electromagnetic radiation (including infrared, ultraviolet, and visible light), in that luminous flux is adjusted to reflect the varying sensitivity of the human eye to different wavelengths of light.
Scotopic vision is the vision of the eye under low-light levels. The term comes from Greek skotos, meaning "darkness", and -opia, meaning "a condition of sight".
In the human eye, cone cells are nonfunctional in low visible light.
Scotopic vision is produced exclusively through rod cells, which are most sensitive to wavelengths of around 498 nm (green–blue) and are insensitive to wavelengths longer than about 640 nm (reddish orange). This condition is called the Purkinje effect.
The wavelengths that coincidentally match Quantum Dots?
Matching the band gaps?

Band gap; circular array, quantum ring computer, optical ring resonator, ultrasonic phased array antenna (5G), triggered (sunlight-solar cells) controlled release of virus like nanoparticles, encapsulated in liposomes... flu vaccines?

Holman's nanoparticle coating tool works like an aerosol can of spray paint. But instead of spraying liquid droplets of paint, it sprays nanoparticle dust 😉
In 2016, Holman had the idea to use coatings of nanoparticle dust to enhance the efficiency of tandem solar cells. Soon after, he and his research team realized other industries could improve their products by applying nanoparticles to their surfaces.
“The more we look, the more we find,” Holman said.
