Scientists suggest increasing what is understood about exocytosis could one day inform many fields of applied science.

Custom polymer structures can now be 3D printed inside living cells using laser-based fabrication, opening paths to intracellular sensors, cell tracking tags, and embedded microlasers.

Lysosomes are the recycling centers of human cells. Larger molecules are broken down inside the membrane-enclosed vesicles. Malfunctions can lead to neurodegenerative diseases such as Parkinson's.
