Question: How can foliar iron be stabilized and retained under rainfall?

Design and findings: Mesoporous silica co-loads ferrous ions and carbon dots, while an outer tannic-acid/iron gate combines iron stabilization, pH-responsive transport and foliar retention.

Scope: The findings concern iron stability, release and leaf interactions under the tested conditions, rather than demonstrated performance across all crops and climates.

Question: How can materials, DNA assembly and nanoprobes amplify analytical signals?

Design and findings: Amino-functionalized cobalt MOF nanosheets, DNA catalytic hairpin assembly and thionine-labeled gold nanoprobes provide multilevel signal amplification. Under optimized conditions, chloramphenicol detection reaches 3.33 pM across a 10 pM–50 nM linear range.
