DNA nanobots are microscopic structures that assemble themselves from DNA components. Recent research in DNA nanotechnology has brought self-assembling nanorobots a step closer to reality, but getting them to build into large objects is still challenging. Although, UNSW researchers, with colleagues in the UK, have figured out a piece of the puzzle and are a step closer to controlling self-assembling DNA nanobots’ dimensions.
Nanobots can already build themselves on a tiny scale, and scientists can program pre-made ones to do minimal and straightforward tasks. Medical researchers have used them to deliver drugs to cancer cells or position small electrical components.
Medical researchers are already able to build nano-scale robots that can be programmed to do very small tasks, like position tiny electrical components or deliver drugs to cancer cells.
Recent strides in micro- and nanomanufacturing technologies have sparked the development of micro-/nanorobots with enhanced power and functionality. Due to the advantages of on-demand motion control, long lifetime, and great biocompatibility, magnetic propelled micro-/nanorobots have exhibited considerable promise in the fields of drug delivery, biosensing, bioimaging, and environmental remediation. The magnetic fields which provide energy for propulsion can be categorized into rotating and oscillating magnetic fields. In this review, recent developments in oscillating magnetic propelled micro-/nanorobot fabrication techniques (such as electrodeposition, self-assembly, electron beam evaporation, and three-dimensional (3D) direct laser writing) are summarized. The motion mechanism of oscillating magnetic propelled micro-/nanorobots are also discussed, including wagging propulsion, surface walker propulsion, and scallop propulsion. With continuous innovation, micro-/nanorobots can become a promising candidate for future applications in the biomedical field. As a step toward designing and building such micro-/nanorobots, several types of common fabrication techniques are briefly introduced. Then, we focus on three propulsion mechanisms of micro-/nanorobots in oscillation magnetic fields: (1) wagging propulsion; (2) surface walker; and (3) scallop propulsion. Finally, a summary table is provided to compare the abilities of different micro-/nanorobots driven by oscillating magnetic fields.

As I have not had the vaccination (and have no intention to), I will ask others: is there a record showing which syringe is being used? Or do they simply pull out a syringe, fill it with vaccine, toss it in the waste, and move on?
Chips could be programmed to the individual after injection.
Or perhaps the need to wear a mask after vaccination is because it takes weeks to produce immunity? It's not instant, you know.
I just wonder what would happen if thw people who can stick a magnet to their arm can go into an MRI?
First, we have the idea that RFID isnt really the tech they would be looking at for tracking this sort of thing. I suspect quantum dots would be a much more likely scenario.
