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.

Chemists make Play-Doh/Lego-like hybrid to create tiny building blocks

Play-Doh and Legos are among the most popular childhood building blocks. But what could you use if you wanted to create something really small—a structure less than the width of a human hair? A team of chemists has found that this can be achieved by creating particles that have both Play-Doh and Lego traits. These "patchy particles" are 1/200th the width of a human hair and can form endless architectures from a handful of basic pieces. And unlike their larger counterparts, these particles can self-assemble. This process—self-assembly of predetermined micro-architectures—is similar to the way atomic crystals self-assemble from a specific mixture of atomic building blocks.
