The research on magnetically activated and controlled microbots for drug delivery and biopsies continue. The latest research from South Korea has designed ‘cages’ to carry drugs that are effectively the closest microbots have to a delivery truck form factor for delivery to the brain or eyes. The tradeoff is tininess versus more capacity; more drugs, more effectiveness. Published in Advanced Materials (link to full text PDF), short summary in PopSci, very long and thoughtful article on how nanobots work in IEEE Spectrum by French scientist-pioneer Sylvain Martel of École Polytechnique de Montréal, who projects their first use will be to fight cancer.
