Information to support DD is available. Much of it is cited on this board but a board is no place to do due diligence. You've raised many question in the past two weeks. All can be answered, to a degree sufficient to earn my investment perhaps you will feel the same, by undertaking a research program. This board is an entertaining virtual playground for technology/bioscience nerds and gadflys. It can be entertaining but is often frustrating. This board is not a research center. It can be very educational. (thanks BK, ZF, NP and others) The board is ideal to discuss research findings or to comment on market activity. It's frightening how many potential NNVC investors appear to base their financial decisions on answers to questions posted here and/or in response to unsolicited opinions. If you are intrigued by the potential, financial or scientific, of NNVC invest your time before you invest you money but in either case invest where the information comes free from attachment to investor's financial ambitions.
