#nanoparticles

1 post1 participant0 posts today

Golden eyes see again. A retinal prosthesis with the potential to restore #vision lost or degraded vision due to age-related macular degeneration using gold #nanoparticles, which allows activation of cells in the eye using an infrared laser. Hope it'll work.
Naturally, the visual of it is got me just as interested as the medical implication. Think of the visuals for a Sci-Fi story, ho #writers - the old person with their eye reflecting in gold.

#SJSU #MossLanding Marine Laboratories has conducted testing for heavy metals:

"...unusually high concentrations of heavy-metal #nanoparticles... at Elkhorn Slough... following the recent fire at the nearby #Vistra Power Plant's li-ion battery storage facility... within a radius of approximately 2 miles... measured a dramatic increase (hundreds to thousand-fold) of the three heavy metals Nickel, Manganese and Cobalt."

#Nanoparticles can focus light way stronger than any lens, and allow us to make light and matter interact in unusual ways. But what is the best shape for a #nanoantenna to enhance light emission from molecules? A cool simulation method called topological optimisation has previously shown that a certain "infinity antenna" shape is best for this enhancement. Here, we fabricate these antennas and show how strongly they enhance light emission.

Nanoplastics Are Entering Our Bodies
socialistproject.ca/2023/07/na

The air is plasticized: minuscule plastic fibers, fragments, foam, & films shed f. plastics are perpetually floating into & free-falling on us f. the atmosphere. Rain flushes micro/nanoplastics back to Earth.

Wind & storms carry microplastic particles through the air for dozens, even 100s of miles before depositing them back on Earth.
