What to know about Scientific Innovation

Researchers at Purdue University have developed a high-throughput mass spectrometry platform using desorption electrospray ionization (DESI) to both analyze and synthesize chemical compounds. The system utilizes fast-moving microdroplets to accelerate reactions at room temperature without the need for catalysts or high heat, potentially speeding up drug and agricultural product development.

What happened

Fast-moving droplets synthesize key drug compounds at room temperature, no catalysts needed Lisa Lock Scientific Editor Robert Egan Associate Editor Chemical reactions are the backbone to nearly all biological processes, including those used to make new…

Why it matters

However, these reactions can often take considerable time and require harsh conditions or materials—potentially inhibiting the timely development of life-changing drugs.

Common ground

Purdue University researcher Graham Cooks and his team at Aston Labs have developed a method that uses tiny, fast-moving droplets to speed up chemical reactions without the use of high temperatures or catalysts—substances that are typically needed to…
