Nanodx, IBM partner on cost-effective diagnostics platform for various diseases, page-6

"The COVID-19 pandemic drove the unique collaboration between Southborough, Mass.-based Nanodx and Armonk, N.Y.-based IBM, with the increased awareness and demand for rapid point-of-care (POC) testing. It was largely what made Nanodx reach back out to IBM to close the deal after the two companies had had initial discussions – and did some coding – around licensing IBM’s metal-oxide semi-conductive (CMOS)-compatible nano biosensors a few years ago. This technology has been known to enable cost-effective, rapid, and high-volume production."

“To be able to combine Nanodx’s technology and biosensing with that of the CMOS technology from IBM is really a massive gamechanger,” said Joshi. “It's extremely rare for two companies of very different sizes to collaborate on something like this that could really transform a major marketplace,” he added.The collaboration was also made possible thanks to the $18 million in financing Nanodx recently raised.

Having read this again, I think IBM are providing the nanoscale semiconductors to enable the system to operate. They are licensing out an aspect of the hardware and the code to make the platform work. They are not creating the nanowire sensor - which is what Sensera is doing.

"CMOS technology" and "coding" refers to the actual hardware of the measuring unit, not the disposable sensor in the testing chip - .
Sensera are not aware of IBMs involvement as its none of their business who writes the code for the platform and what memory / CPU it uses. Obviously the interpretation of results at a nanoscale requires hardware hard to create, and this was outsourced by Nanodx to IBM.

Well, I just bought some more - EUA approval within 2 months.
