Single-Use Technology: The Next 5 Challenges to Conquer

Now that single-use technology plays a part in nearly all bio-production processes, what is next? Several challenges remain that are still serious enough to delay or even stop the use of single-use technology, which in turn can extend the time to market and increase the cost of lifesaving biopharmaceutical products. Of the existing difficulties, which five are the most critical?
