摘要

(Figure Presented) Cocaine cracked: The gel-sol transition of an enzyme-caged hydrogel has been efficiently controlled by target binding events, which trigger release of the enzyme to take part in its catalytic role for signal amplification (see picture). As low as 20 ng of cocaine can be visually detected within 10 min without any aid of sophisticated instrumentation.
