Scientists have discovered that the internal shape of tiny drug-delivery particles—called lipid nanoparticles—has a big impact on how well our cells absorb them, paving the way to more efficient ...

A simple, chemical materials model may lead to a better understanding of the structure and organization of the cell according to a Penn State researcher. "Cells are interesting because they show ...

To create A1 lipid nanoparticles for delivering mRNA to target cells, scientists at the University of Pennsylvania used A3 coupling. A3 refers to the amine–aldehyde–alkyne coupling reaction, which the ...

All the information about a person’s health (e.g., their exposure to chemicals, their inherited risks, their current illnesses) lies within their molecules, according to scientists. Thus, a team of ...

As anyone who has experienced an annoying alternation between dry and watery eyes can confirm, tears alone aren't enough to keep the eye from drying out. A microscopically thin film of oils known as ...
