Exciting change is on the way! Please join us at nsf.gov for the latest news on NSF-funded research. While the NSF Science360 page and daily newsletter have now been retired, there’s much happening at nsf.gov. You’ll find current research news on the homepage and much more to explore throughout the site. Best of all, we’ve begun to build a brand-new website that will bring together news, social media, multimedia and more in a way that offers visitors a rich, rewarding, user-friendly experience.

Want to continue to receive email updates on the latest NSF research news and multimedia content? On September 23rd we’ll begin sending those updates via GovDelivery. If you’d prefer not to receive them, please unsubscribe now from Science360 News and your email address will not be moved into the new system.

Thanks so much for being part of the NSF Science360 News Service community. We hope you’ll stay with us during this transition so that we can continue to share the many ways NSF-funded research is advancing knowledge that transforms our future.

Detecting biological contaminants in water and pharmaceuticals

Spheryx Inc., a small business funded by the National Science Foundation (NSF), created a technology to monitor, count and characterize microscopic particles in a variety of fluids, such as water, chemicals or even pharmaceuticals. The Food and Drug Administration has identified groupings of proteins, called protein aggregates, as a significant safety hazard for biologic pharmaceuticals, which are widely considered the most promising class of new drugs. Protein aggregates are very hard to detect, and ingesting them can lead to severe immune reactions, sometimes even to death. Spheryx's technology can detect, monitor and characterize protein aggregates suspended within pharmaceutical products, leading to safer products for the consumer and reduced manufacturing cost for the manufacturers. The technology is based on holographic video microscopy, which uses a microscope with laser light to create holograms of particles within cells. The holograms encode the 3-D information about the particles, and Spheryx extracts information to determine whether there are protein aggregates in the sample. Spheryx is supported by America's Seed Fund powered by NSF, a $200-million program that awards research and development grants to small businesses and startups, transforming scientific discovery into products and services with commercial and societal impact.
