Research:
Diagnostic Technology has a history in secondary metabolite research and cyanobacterial biotechnology spanning two decades. In collaboration with Professor Brett Neilan, Diagnostic Technology has been awarded 8 grants by the Australian Research Council (ARC) that have advanced the understanding of cyanobacterial secondary metabolites, developed molecular detection methods for cyanotoxins, and produced complex secondary metabolites in heterologous systems. Diagnostic Technology continues to support the advancements of secondary metabolite research through collaborations with external research groups.
The start of 2020 has seen the establishment of an inhouse research lab within the Belrose site. Current research conducted at the newly fitted lab aims to develop a reliable production source for cyanotoxins and their intermediates as analytical standards.
