Clear sinus blockages with micro robots .
Inspired by a recent article Biologically inspired micro-
robotic swimmers remotely controlled by ultrasound
waves (linked) - I envision a doctor filling a syringe with
a whole fleet of these in a saline solution, then
injecting them into a patients nostril(s). The doctor
could direct them
through the sinuses and eustachian
tubes to clear blockages. Could be much faster and
more thorough than nasal lavage.

||Little snot-salmon swimming upstream: I had a similar thought,
about using such botlets to deliver biocides to infection sites in
the nose. [+]
||Absolutely. Drug delivery was also in my original
writeup but I decided to keep it short and focus on
clearing blockages. Even there, they might need
to apply short acting anesthetics or paralytic
agents to keep the patient from sneezing them out
during the procedure.
||Theyll have to be very precisely controlled, and
probably designed to disintegrate into something
harmless after a short time also. Not sure if its
possible to get them all out when the job is done,
or to keep any from going astray while theyre
working. Wouldnt want a rogue Nasal Bot picking
away in the lungs or the brain.
||Thats the sort of thing you only read about on HB,
but it could happen!
