13.4 kHz (you dropped a decimal there), and no, it is far lower than the commercial radio bands. I suspect that newer chips would use a much higher frequency, as that cuts down on the physical size of the oscillator components. The downside is that more power is needed and component placement on the substrate becomes critical due to unintentional reactances.
Your link essentially says what I said but in a more mathematical manner. Classic antenna design is useless for such small devices, so inductance antenna design is used (this is a miniaturized version of the classic coil antenna design). However, it is not correct to say that it is an inductor instead of an antenna... the two are actually related. It is an inductive antenna design that allows for transmission over very short distances.
Understand that, where possible, I try to keep any explanations on this forum in layman's terms or at least give a superficial explanation when I cannot. My purpose is to promote understanding, not to wow someone with big words.

All that for what is clearly BS?
You owe me 5 mins...for the magnetism BS, not your thread..lol

Here lately I have been seeing several reports about magnets sticking to one's body, apparently attracted by an RFID chip. I have been hearing that the RFID chips are being included in vaccines.
I was actually under the impression that the QDs were a barcode and that they were not necessarily truly "quantum." More of just a mix of "stuff" that can be implanted to create something akin to a QR code.
Im also not too sure the QD would be particularly easy to fabricate, however, that centralized database inherent to the RFID tech would be advantageous in some respects. But, that central database also means many points of social vulnerability. With security specifically, I think it would be a toss up. I wouldnt be surprised to see both of them in action simultaneously, if we take the conversation outside of the framework of this fun debate
The specific individual is actually very effectively addressed through social pressure to comply, using "community policing" hotlines for tips, etc.

Abstract
Magnetic nanosensors have become attractive instruments for the diagnosis and treatment of diferent diseases. They represent an efcient carrier system in drug delivery or in transporting contrast agents. For such purposes, magnetic nanosensors are used in vivo (intracorporeal application). To remove specifc compounds from blood, magnetic nanosensors act as elimination system, which represents an extracorporeal approach. This review discusses principles, advantages and risks on recent advances in the feld of magnetic nanosensors. First, synthesis methods for magnetic nanosensors and possibilities for enhancement of biocompatibility with diferent coating materials are addressed. Then, attention is devoted to clinical applications, in which nanosensors are or may be used as carrier- and elimination systems in the near future. Finally, risk considerations and possible efects of nanomaterials are discussed when working towards clinical applications with magnetic nanosensors.

Drug delivery
Magnetic nanoparticles are considered ideal candidates for drug delivery for several reasons. Their large surface-to volume ratio allows for a high loading with active substances. Moreover, these MNPs can be directed by a magnet and facilitate targeted delivery of drugs. Finally, stable dispersions and fast transportation in fluids can be realized due to the small size of the MNPs/b][.
