<abstract abstract-type="toc"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <graphic position="anchor" id="ga" xlink:href="ark:/27927/pgj1zkbnphw" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" />A novel spiro-rhodamine B lactam derivative, which can be coupled to Fe₃O₄ NPs and act as a Cu²⁺-selective visual sensor is reported. It can be used to directly detect as little as 50 nM of Cu²⁺ in river or tap water by only naked-eye observation.</p> </abstract>
