Technology Development

2Blades seeks to advance technologies from the initial discovery stage into products.  While in some cases 2Blades has undertaken some level of development work internally, in others this is done through collaborations or licensing of technologies directly to partners with commercial delivery capacity.  For example, our work with the EFR receptor has been carried out through a combination of 2Blades direct support, collaborations and licensing.
