First: bio + ballistics = biolistics

coated with DNA or RNA

Propelled at tissue using
pressurized helium
What if we use dye instead of DNA?
Lipophilic dyes DiA, DiD, DiI, DiO, …
Second: DiO + Biolistics = Diolistics
(Gan, et al. 2000)

Biolistics
Diolistics
Requires hours to express
Diffuses throughout most neurons (~200 µm diameter) in 30 min
Can severely alter cell metabolism
Does not affect cell health (apparently)
