Molecule World

There was a time when molecular models could only be viewed with high-performance computers and complicated software.  

Today, scientists of all ages can use Molecule World™ to explore thousands of fascinating biological and chemical structures easily on an iPad®.

Molecule World puts over a hundred thousand structures of proteins, DNA, RNA, and other chemicals at your fingertips!
