heres one to watch, page-5

This is definitely a stock to watch in terms of the value of its supercritical fluid technology. Platform technologies such as this are probably the safest bet in a relatively unsafe biotech marketplace. They have a number of contracts to deal with processing of ultrafine formulations but there a number of other uses of the supercritical technology.

I don't have any of these but would probably have bought some recently if I had spare funds...
