#Tiny pump builds polyrotaxanes with precision
“#Tiny pump builds polyrotaxanes with precision” Northwestern University researchers have developed the most precise way to build polyrotaxanes, a mechanically locked polymer for slide-ring gels, battery electrode materials and drug-delivery platforms. A necklace-like molecule made with rings threaded onto a polymer string, polyrotaxanes are notoriously difficult to construct. A new method from the laboratory of…
