Ann: Appendix 4D and Half-Yearly Report, page-4

Personally, I'm glad it's on hold. At last someone with balls to make a sound commercial decision to focus on the chip that works and mothball the one that's been impossible to fabricate. It's no surprise either as it has been clear for several reporting periods the LumiMEMs was a major headache.
They may well sell the IP to someone who can fabricate it.
It makes the utmost sense to put maximum effort into the spectrometer chip which will lead to earlier commercial ventures.
I would go further, I would cut the connection with the UWA.
Revenue from Hydrix was 1.4 million, not bad considering the takeover was only finalised in mid November, so we've only had 3 months revenue from them.
I would say that a decision has been made to step away from R and D of further sensors, it would seem we are going the route of licensing and purchasing.
The CEO wants to make money, not keep spending it on Research which more often than not ends up a dead end.
We are getting there, a transitional period from research to a commercial design and production establishment.
Apart from the name, the Company has changed.
Now we might get somewhere, I've changed my rating from hold to Buy.
