It's great to get confirmation that they already have interested parties. Its obvious that the PR is meant to accelerate the spread of news of this opportunity with Nanologix to the diagnostic community. The two companies that have already signed confidentiality agreements have a head start and hopefully will feel pressure to lock up an agreement with Nanologix quickly before others come knocking.
ANY deal (limited to detecting SARS-CoV-2) that doesn't cost the Company money would be great for Nanologix as the exposure itself would be worth $$$ in free advertising. This Company's greatest hurdle has been gaining legitimacy with the diagnostic community. Validation would open the floodgates for the N-Assay as well.
