When you don't know the answer to a question, ask an expert. If the question is really big, ask more experts. If you have a collection of difficult questions, run a poll of many experts. That, in effect, was the impetus for Eden Biodesign to survey 670 BioPharm International subscribers with questions as to what will be the development mechanism to achieve safe, effective, and cheap new medicines.

Disposable products and systems have come a long way since they first entered the small-lab market in the 1970s. Today they are available for practically every aspect of biopharmaceutical manufacturing. Disposable systems are used for filtration, clarification, purification, and separation applications used in the production of vaccines, monoclonal antibodies, and other therapies. As the use of disposable systems grows, the concept of a completely disposable manufacturing process is becoming a reality.

A profusion of present-day bioreactor and fermentor systems offers remarkably diverse capabilities, ranging from microfluidics to bulk production vats, simple petri dishes to complex artificial organ cultivators, and suspension, adhesion, perfusion, and many other culture management methods. Each of these systems is well suited to address specific research problems, but few are widely adaptable to diverse experiment demands - such as those conducted in space.
