Engineering tiny nano-bots that actively and autonomously act for desired applications is envisioned to be part of future nanotechnology. Mimicking biomotors, scientists use catalytic reaction to power artificial nano-devices and nano-machines. Self-powered micro-nano-bots can be fabricated from multiple materials, shapes and by various methods, and have demonstrated several proof-of-concept applications in robotics, Lab-chip biosensing, nanomedicine, and environmental field [1].
We fabricate nano-bots from mesoporous silica nanoparticles, microcapsules, electrodeposited microtubes and rolled-up thin films into microtubular jets. Very recently, we have found that hybrid micro-bio-bots combine the best from the two worlds, biology and nanomaterials providing very promising bio-related applications [2].
What can nano-microbots do for us? Here, I will present our recent developments in this fascinating field focusing on two applications, i.e. towards nanomedicine [2,3,4] and water remediation[5,6].
Keywords: nanomotors, nanotechnology, drug delivery, active matter, self-propulsion, bots.
