Australian Patent 2021903898 Detection and quantification of nucleic acids, page-8

Thanks for finding this @flammo. I believe you and others here have found the connection and it is GRAPHENE.

The properties of graphene have been well researched over the years and now AXE is implementing some of these properties in building sensors and chips.
So as I understand it, there are the graphene-based chemical sensors ( A1 biochip applications) that can detect minute quantities of whatever needs to be measured. Then the information is converted to electric pulses and this is where Silicon plays a part. Graphene sheet suspended in a silicon dioxide substrate ( The integration of graphene and silicon that yesterday's announcement may be about).

Additionally, we know how graphene can produce useful quantum effects at room temperature for the 12CQ. In Archer's case the CEO himself has produced synthetic graphene in a lab and knows the structure of graphene inside out.

And the real clincher is that the planar nature of graphene lends itself to the current fabrication process of CMOS semiconductor chips.

Amazes me how all this combines to make both chips a viable product. All with the magic of graphene.
